substr_count or count_chars would work.

You missed the point.

Anyway, stop flogging a dead horse. Stupid questions have stupid answers,
unfortunatly mine was one of the stupid answers - in hind site, I agree it
was an inapropriate thing to say.

In test_oben.php I want to insert two strings.
pressing the "Display strings"-button will output them in the button frame.

Only pressing the "Display concatenated strings"-button should output the concatenated string,
but this does not work, and I do not understand why.

Please give me a hint !

$var3 is defined as

$var3 = "$var1$var2";

in the body of the if ($button1) statement !?

I have a class which builds a set of tabs...the class expects an array in
this form

array("Site Info"=>"siteinfo.php","Contact Us"=>"contactus.php")..where Site
Info is a link to siteinfo.php.

The build tabs method of the class then loops through the array outputing a
set of tabbed links on the page.

The problem is I am having trouble generating this array from a database. I
need to pull from my query:

$sql->query("select title, page from links");
while ($sql->nextRecord()){

//build the array

}

I have tried arraypush but can only get it to work with a standard
array...how can I do this?

Thanks,
Eddie

Just curious as to how people handle search engine optimization when most of
the page content is dynically built from the db. Doesn't the bots need to
crawl the static pages and match your keywords to actual words in the file?
Also, is it not a good idea to put all your meta keywords into a
header.inc.php script that is then pulled into each page when it is loaded?

Thanks,
Eddie

Hi Edward,

A few things first:

1) Match keyword to actual words in the file:

Not sure what you are talking about but if you are referring to Meta tag
keyword data... this has been primarily outdated for several years now.
Do SE's read meta data? Yes and no, but rest assured if you are trying
to make it into top page indexes, meta data will do nothing to help
bolster your rank. It's generally considered useless.

2) Doesn't the bots need to crawl the static pages:

Bots can crawl dynamic pages with query strings in the URL. However, how
deep they spider is still in question. If you can create static looking
pages from dynamic content with URL re-writing you're much better off.
Example: after a client came to me to help with their search engine
marketing, we discovered only 200 of their 1500 products were being
indexed. With url-writing we were able to get all 1500 into Google and
Google continually spiders on a daily basis.

3) If you are concerned about search engine optimization for yourself,
or a client, you need to either A) learn the ins and outs yourself (a
lot of time and research) or work with a consultant to help you optimize
code, pages, copy, links, etc.

Good luck.

Aaron

All pages are static once you load them, the letters are not moving
around ;-)

Does not hurt. Even better, use meta keyword and description based on
the main content of the page.

Practically, only Google matters these days as most sites get over 70%
of leads from Google.

For Google, it matters that your pages are served as fast as possible.
If your pages are taking too long to be served, Google assumes it is
causing too much load to your site and slows down giving more time

There is a myth regarding the interpretation of this explanation for
Google not indexing dynamic as many site pages because of the use of URL
with query parameters (?some=thing&this=too).

http://www.google.com/webmasters/2.html#A1

Query parameters is is not the reason why Google does not index so many
pages. I can demonstrate that just by let you see that Google indexes
for 700.000 pages of php.net, many of which have many query parameters:

http://www.google.com/search?q=site%3Aphp.net

So, do not bother with all those bogus advices telling you to use URL
rewriting because that is not what matters. What matters is that your
pages are served as fast as possible cause as less load to your server
as possible.

If your pages are generated with content taken from a database, you
would better use some content caching to avoid spending too much time
making repetitive database queries which is usually your site's bottleneck.

You may want to try caching whole pages or just parts using for instance
this class. It is very robust as it uses file locking to prevent cache
file corruption during updates that may happen during surges of many
simultaneous users accesses:

http://www.phpclasses.org/filecache

If you can, also use some PHP script caching engine, like for instance
Turck, which is free and provides great PHP execution speed up by
avoiding the implicit PHP script compilation step:

Since Yahoo! Dropped their affiliation with Google, many, including

is not the case anymore.

Speed is a factor, page size is a factor but the number of query strings
within a URL is why Google (and other bots) only go so deep into a site
0 for fear of getting caught in a endless loop.

They are getting better, however.

It's definitely not bogus information. I can get a site's pages indexed
a lot quicker with URL rewriting than I can without.

Yes, but if you just keep optimizing for Google you will be optimizing
for most of the others that have significant share because Google always
been the most successful in providing relevant results for the users and
  others tend to imitate Google.

My point is that if your pages are served slowly, URL rewriting does not
matter and only a subset of your pages will be indexed. OTOH, if you
make your pages be served very fast, URL rewriting is not necessary, at
least for Google. I know that for experience. I have seen it several
times Google crawling thousands of pages with no URL rewriting.

As for other search engines, I don't know because it is possible that
they try to copy Google crawling logic the way they understand it, which
may not be the actual way it works as Google does not disclose it .

Try calling ob_end_flush() at the top of your script. Although I believe some
browsers will still buffer a portion of the output before displaying. But if you're
running from the command line it should display in real time. HTH...

Use this at the top of the script:
  ini_set('output_buffer', 0);

Or, as I usually set up for my cli environment (since they ususally
desire no buffering), create a php-cli.ini file that has
output_buffering turned off.

The "output_buffering" setting cannot be controlled via ini_set(), at least
according to the manual. I want to say that I confirmed this a long time ago but I
can't recall for sure.

That's a good idea. But to do it on a per script basis (where it's undesirable to
alter the global buffering setting) I think the only way is to call ob_end_flush()
at the top of the script...

Another alternative is to change settings with shbang:

  #!/usr/local/bin/php -d output_buffering=0
  <?php
  // continue on with no output_buffering.

Of course this will only work when the script is set executable and
is ran like a any other program, instead of 'php script.php`

iirc, by default mysql uses the socket if you connect via
localhost/127.0.0.1 and tcp any other way.

Although a mysql list probably would be more appropriate for this

Hi!

I'm currently developing a nice script that generates OpenOffice SXW files
by filling the content.xml (which is UTF-8 encoded) with database content.
While trying to do this I found out that utf8_encode('"') (charcode 147)
returns 'Â"'. But when I checked the whole result in OffenOffice '"' is
displayed as square (character unknown?!). So I made some tests with UTF-8
conversion (even mb_* functions) and recognized that characters between 128
and 160 returned by utf8_encode() don't seem to match the standard. As
mentioned above '"' is returned as 'Â"' but should be 'â?T' (as you will get
it using UltraEdit for conversion).

Does anyone can give me some explanations here?

I'm not familiar with this UTF-8 / bit-conversion stuff, but I don't think
PHP does what it's supposed to do here. For a first workaround I simply
coded a custom_utf8_encode() that uses an own char map to override this
misbehaviour (see below). Can someone help my out with this strange bug?!

                    140 => 'Å'', 141 => 'Â�', 142 => 'Ž', 143 => 'Â�',

        $chrVal = ord($str[$i]);

You have it backwords.. -333371788 is signed and the 3961595508 is
unsigned.

But...

<?php
$dec = -333371788;
$unsigned = sprintf("%ul", $dec);
print $unsigned; // == 3961595508

Do note that php doesn't have native unsigned numbers so doing
something like this wont work right:

  printf("%d", $unsigned); // == 2147483647

So to convert it back you have to do something like:
  printf("%d", $unsigned+0); // == -333371788

Yes, but once it become a hex string (after dechex()), all that info is
gone. I think the way to handle this situation is to use pack & unpack.

OK, that makes sense. But here's the problem: I receive binary data
from SuperSPARC (big-endian), which I need to unpack according to
certain documented type definitions. For example, let's say that $msg
has the value "3961595508" and is packed as an unsigned long integer
(on the remote SPARC). But when I receive it, and unpack it...

$unpacked = unpack('Nval', $msg); // N for unsigned long integer,
big-endian (SPARC)
echo $unpacked["val"];

...the output value is "-333371788". (???) Which tells me that PHP is
NOT unpacking $msg as an unsigned long integer, but rather as a signed
integer (since unsigned integers cannot be negative).

Now, thanks to your suggestions, I can convert that number back to an
unsigned integer—or at least make it positive. But I shouldn't have to
convert it, should I?

Not necessarily, it mostly due to the limitation that php doesn't
have unsigned integers. I have a patch for php that will return a
unsigned integer as a string, but I havn't gotten it put into php
yet.

2. in PHP can't connect either( $dbconnect=OCILogon($dbuser, $dbpass, $dbname))

So I was wandering if you can help me - either give me some advises or may be point to the source where I can retrieve the info I need.

Hello:

I am just starting to learn php and have been reading tutorials that I
have found on the Internet.

The one I am reading now is:

http://www.freewebmasterhelp.com/tutorials/phpmysql/1

The problem I am having is with these two scripts.

Script 1:

(This script displays some forms to type in Contact information.)

<form action="insert.php" method="post">
First Name: <input type="text" name="first"><br>
Last Name: <input type="text" name="last"><br>
Phone: <input type="text" name="phone"><br>
Mobile: <input type="text" name="mobile"><br>
Fax: <input type="text" name="fax"><br>
E-mail: <input type="text" name="email"><br>
Web: <input type="text" name="web"><br>
<input type="Submit">
</form>

Script 2:

(This script (saved as insert.php) is called by Script 1 after
information has been typed into the above form.)

<?
$username="localuser";
$password="unknown";
$database="Contacts";

mysql_connect(localhost,$username,$password);
mysql_select_db($database) or die( "Unable to select database");
$query="SELECT * FROM Contacts";
$result=mysql_query($query);

$num=mysql_numrows($result);

mysql_close();

echo "<b><center>Database Output</center></b><br><br>";

$i=0;
while ($i < $num) {

$first=mysql_result($result,$i,"first");
$last=mysql_result($result,$i,"last");
$phone=mysql_result($result,$i,"phone");
$mobile=mysql_result($result,$i,"mobile");
$fax=mysql_result($result,$i,"fax");
$email=mysql_result($result,$i,"email");
$web=mysql_result($result,$i,"web");

echo "<b>$first $last</b><br>Phone: $phone<br>Mobile: $mobile<br>Fax:
$fax<br>E-
mail: $email<br>Web: $web<br><hr><br>";

++$i;
}

?>

I have created the database Contacts. It is a MySQL database. I open
the first script and enter my contact data, press Submit, and I believe
the second script is then called.

I go and check my Contacts database and a new record has been added, but
it is empty. I am guessing that the values assigned in the first script
are not being seen by the second script and that the empty variables are
being written to the database.

Is there something that has to be done to php so that it sees these
variables? Is this an operating system issue? Anything else I should be
looking at?

Other data:

Server Machine: Sun Sparc 20 with Solaris 2.6, Apache 2.0.49, MySQL
4.0.17, PHP 4.3.7.
Remote Machine: Homebuilt running MS Windows 2000, Mozilla Firebird 0.7
browser

If there is a better list for beginner questions, please let me know.

Thanks.

register globals is off, so all of your variables are in the POST array

$_POST['first']
$_POST['last']

etc. Replace all your variable references with the appropriate array
references and you'll be off to the races.

Jay:

I edited the insert.php file and changed the $query line from what was
previously posted to that below (all one line):

$query = "INSERT INTO Contacts VALUES ('','$_POST[first]','$_POST
[last]','$_POST [phone]','$_POST[mobile]','$_POST[fax]','$_POST
[email]','$_POST[web]')";

This works like the article says it should.

Thank you for your help.

Hi,

Is it possible to use PHP to detect the type of browser accessing my site.
For example if a PDA is using it I would prefer not to include large
graphics...

Many thanks for your help

you can check the user-agent, no gaurantees what if anything that is
sent is accurate.

$_SERVER['HTTP_USER_AGENT'];

I am trying to send some encrypted data from a php application to be
decoded in a .Net application. Both apps encode/decode a given string
but generate different encrypted results. Anyone have any idea? Code
to follow:

php====>
<?php

// Designate string to be encrypted
$string = "This is a test";

// Encryption/decryption key
$key = pack('H*',md5("mysecretkey"));
echo "PHP:KeySize:";
echo mcrypt_get_key_size('tripledes', 'ecb')*8;
echo "<BR>";
echo "PHP:BlockSize:";
echo mcrypt_get_block_size('tripledes', 'ecb')*8;
echo "<BR>";

// Encryption Algorithm
$cipher_alg = MCRYPT_TRIPLEDES;
#$cipher_alg = ;
#$cipher_alg = ;

// Create the initialization vector for added security.
//$iv = mcrypt_create_iv(mcrypt_get_iv_size($cipher_alg,
MCRYPT_MODE_ECB), MCRYPT_RAND);

$iv = pack("H*","ec787813562c5be0");

// Output original string
echo "PHP:Original string:$string <br>";
echo "PHP:Original Key:". base64_encode($key)."<br>";
echo "PHP:Encryption Method: tripledes <br>";
echo "PHP:IV:".base64_encode($iv)."<br>";

// Encrypt $string
//$encrypted_string = mcrypt_encrypt($cipher_alg, $key, $string,
MCRYPT_MODE_CBC, $iv);
$encrypted_string = mcrypt_encrypt($cipher_alg, $key, $string,
MCRYPT_MODE_CFB, $iv);
$decrypted_string = mcrypt_decrypt($cipher_alg, $key,
$encrypted_string, MCRYPT_MODE_CFB, $iv);
echo "PHP:Encrypted string
Base64:".base64_encode($encrypted_string)."<br>";
echo "PHP:Decrypted string:$decrypted_string";
?>
