I've been running Apache on 98SE (I agree - DON'T ASK!) for most of this
year without ny issues at all. Win98needs reboots a few times a week, but
it's not Apache's problem. I also run PHP4.0.6 and 4.0.8-dev and MySQL
3.23.43 and they all work and play well together. Just to keep my sanity, I
also run a linux server too :). It helps me knowing that computers aren't
supposed to have to be rebooted to keep them stable!
-- Gaylen gfraley5"Richard S. Crawford" <rscrawford
I would agree with trying Apache on your Win98 box; but be warned that the current Apache release is only supposed to be stable on NT platforms. Since I have win2k it's not an issue for me, but it might now work on Windows 98.

Jeez michael, i'm sorry but i am not going to go through all of your code.
I do have a suggestion for you, without looking at the code.
As you know. php has flexible variables. I mean, if you say $a=1 then $a is an integer, if you say $b='i' then $b is a string. Very easy to make code quickly, but for the larger scripts it can be a pit trap.
I think that while you intended the variables to be numbers, they somehow turned into strings. Maybe you added a (empty) string somewhere ($a .='').
Several ways to deal with it. First have a look at what is in the variable:
echo '<hr>string "a" is ['.$a.']'; i always add something around the string to see spaces.
Another thing you can try is to force the value into an integer. I think something like
$c= intval($a) - intval ($b);
but have a look around the manual to be sure.
hth, let me know at my own email if it helped?

I think you have things mistaken. What you want is to EXTEND an existing object with new variables and functions. See class CLASS_NAME EXTENDS OLD_CLASS.
This is inheritence, a very good thing that OOP has. It means that the new clase will have all the properties that OLD_CLASS had, plus the new ones you add to it.

No problem, that's what snip is for. ;-)

<checking OOP books> I think that's not how Objects work in a real OOP aplication, and I think yu should think about using EXTENDS. </checking OOP books>
You can create new classes that extend the same OLD_CLASS, so I can't imaging why you don't want to extend it?
P.D.: Maybe you need something even more powerfull, that PHP doesn't have at this moment. Multiple extends (create a new class that extends more then one class).

Sorry for the TOO FAST RESPONCE! :-) $Core is one object, and Error and DB are properties of the object.
Let me put it clearer. You have an Error object, and you now want to make a DB object, with the same properties of the Error object. Just extend it.
Personally I have never made an object that ha other objects definied inside it, but who knows....

Hi,
Would someone please give me a few pointers on how to generate a simple PHP to check for user's name and password before directing to a directory?
e.g., I have a index.php with a form where I have action="login.php". How would I write login.php to check username and password if I have them hard coded in login.php and if authentication fails the user is directed back to index.php? Is this safe?

Looks like the variables are not passed correctly or are not being coded to PHP variables (I know there is a PHP option to do this, but can't remember it). Check: magic_quotes_gpc, register_argc_argv and register_globals (I have them all ON).
> What in the world? Did I forget everything PHP taught me? What the heck > are those weird commas from and I could swear a form element named > "xname" is called in php via $xname ???
The comas are what you have in the $message_raw variable, but the variables you are passing it ($fname for example) are empty
Use var_dump($fname) to see if the variable is set and to which value.

Hey.
Anoyone know how i would go about using one of the internal variables, such as phpinfo() or phpcredits() to send through a socket.
like for: write ($msgsock, ":RWorld PRIVMSG $pnum :phpcredits()\n", strlen (":RWorld PRIVMSG $pnum :phpcredits()\n"));
so it sends the actual information instead of just "phpcredits()". I have tried with $credits = phpcredits(); and placed the $credits in the line above, but that seemed to echo it to my console then send the number 1 through the socket.
Any help on this would be greatly appreciated :)
Tim
attached mail follows:
There is some source code on the php.net site which captures the credits with output buffering and then uses then in the page. Once you have the data in a variable you can do what you like to it.
if (function_exists('ob_start')) { ob_start(); phpcredits(); $credits = ob_get_contents(); ob_end_clean(); }
Maybe that will do the trick.
attached mail follows:
That seems to just give me the first line, of: <html><head><title>PHP Credits</title></head><body> but nothing else after that. Any ideas? :)

I've found this too .. MS-SQL probably ceil()s the parameter in the table create statement to 255 without throwing an error.
Have a quick look at the column you've created and you'll probably find it's a char(255).
> To get larger than that you have to use 'text'
Sounds right to me.

look at http://24.5.29.77:10080/phpinfo.html That's a phpinfo() from a machine that supports pdflib

Thanks! What would people reccommend?
1) just using safe mode
2) using open_basedir and disable_functions

4) Just shutoff the server :)
If (2) or (3) what functions are most at risk? I understand that safe_mode limits quite a few already.

Hello all. I have a problem to solve, but have no idea where to start..
I am writing a site right now that needs to read information from many other web pages on different domains (using fopen). However a few sites have given me the error: "you need to have cookies enabled to view this page". This is because it is the PHP engine that is hitting the web page, and not my browser directly. The PHP engine does not support cookies as my browser does, thus I get this 'no cookies' error.
Is there any way to make these web sites think I have cookies enabled? Can I send specific message headders that would mimic having cookies present? Or can I encode the cookies into the URL in some way? Or better yet, is there a way to allow PHP to accept cookies and send these back to the server every time I request a page?

Hello Robin,
Very simple. :)

$qty is string, so PHP compares "0" with "test" char by char. chr("0") isn't equal "t".
RC> <? $qty = 0 ; if ($qty != "test") print "qty is not test"; ?>
In this case $qty is integer value, so PHP tries to convert "test" to integer value [ integer("test") == 0], so last condition result is FALSE. Is it clear?

The only reason I could see that not working is if PHP is typecasting "test" to (int) in the second example...
$qty = "0"; (string) "test" = "test"; (string) "0" != "test" (evaluates true)
$qty = 0; (int) "test" = 0; (when cast to int) 0 != 0 (evaluates false)
e.g. By comparing an int to a string in the 2nd example, the string is casted to int, and the int cast of "test" is 0.

I just tested those two lines with php 4.0.6 and they both work.
There is a difference though. If you set $qty=0; then $qty has no value. But if you set $qty="0", it has a value.
Type casting is irrelevant in php.
attached mail follows:
> If you set $qty=0; then $qty has no value.
Of course it has a value. The value is 0. Quite distinct from not having a value, or in proper terms, not being set. Try this:
var_dump($qty); $qty = 0; var_dump($qty);
Well, I will save you the trouble, it outputs:
NULL int(0)
> Type casting is irrelevant in php.
No they aren't. Try this:
$qty = 0; if($qty=="test") echo "foo"; if((string)$qty=="test") echo "bar";
This will only output "foo". Not "bar". You could also use the === operator to force PHP to check not only the value but also the type.

No it doesn't have a value. PHP interprets 0 as null.
A very easy way for you to check:
$value=0;
if(!$value) printf("$value doesn't have a value (it didn't even print 0)<br>\n");
$value="0" if($value) printf("$value does have a value if I put "0" instead of 0<br>\n");

Thank you, that was it. I needed to test the variable against both an integer and a string, so I ended up using (string) when I need to compare a string. Rest of the time, it's an integer.

Completely incorrect.

if() doesn't check for null, it checks for a boolean false condition. Does 0 evaluate to false? Sure it does. So does "" and "0". That doesn't mean they are null.
> $value="0" > if($value) printf("$value does have a value if I put "0" instead of 0<br>\n");
That is completely wrong as well. You obviously didn't try your own example. The following all evaluate to false:
if(0) if(false) if(null) if("0") if("")
But the fact that they all evaluate to false says nothing about whether they are values or not. Just like all of these all evaluate to true:
if(1) if(true) if("abc") if(-1)
That doesn't mean that 0 == null anymore than it means that 1 == -1. Just because two values both evaluate to the same boolean state does not mean they are one and the same.

Not quite true. 0 evaluates to false. They are not equal. Try this:
if(0==false) echo "1"; if(0===false) echo "2";
You will find that this only prints "1". 0 and false are distinct and separate values. This is something that confuses a lot of people, especially in conjunction with something like the strpos() function which will return 0 when it matches something at position 0 in the string, but it returns false when there is no match. A lot of people will mistakenly do:
if(strpos("abcdef","abc")) { ... }
and then be confused that the condition appeared not to be met. What they actually should have done was:
if(strpos("abcdef","abc")!==false) { ... }
So be careful and try to think of 0 and false as distinct and separate entities and you will avoid coding mistakes like this.

I don't mean to pick on you, but no, you are wrong. And I am only doing this because so many people get confused on this point and I always see questions related to it.
His lines were:
$qty = "0" ; if ($qty != "test") print "qty is not test"; $qty = 0 ; if ($qty != "test") print "qty is not test";
So his two conditions can be simplified to:
if("0"!="test") echo 1; if(0!="test") echo 2;
Try this code yourself, or his original code if you want. Only the first condition is met and you will only see it print 1.
When you are comparing an integer to a string, the string will get converted to its integer representation. The integer representation of "test" is 0. So the second condition becomes:
if(0!=0)
which is obviously false. Therefore if you cast it:
if((string)0!="test")
You are again comparing a string to a string and PHP will not try to convert "test" to an integer.

Check the link I posted. http://24.234.52.166 There is the code I wrote and it's output. The two lines print. You can explain me why tomorrow they print on my server and not yours.
Good night

try adding the mysql_telepathy extension
(seriously - how should the data get to and from mysql without a connection?)

I you don't open a connection, how is mysql supposed to know which db you are talking to?

poll or pool?
if pool: simply use persistent connections

You get both values as strings from the form. is_numeric checks if the variable is in some was a number (and returns true because it actually is a string representation of a number). is_int and is_double check whether the variable's current datatype actually is "int" or "double" See the manual.
Possible solution: if (is_numeric ($a)) { $a = (double) $a; if (intval ($a) == $a) echo "'$a' is integer"; else echo "'$a' is double"; }

Try again:
$myArray = array('100'=>'jibberjabber','200'=>'morejibberjabber','0'=>'----');
var_dump ($myArray); echo "<br>"; if(isset($myArray[0])) { unset ($myArray [0]); }
var_dump ($myArray);
Outputs:
array(3) { [100]=> string(12) "jibberjabber" [200]=> string(16) "morejibberjabber" [0]=> string(4) "----" } array(2) { [100]=> string(12) "jibberjabber" [200]=> string(16) "morejibberjabber" }
-> index 0 is gone.
