Hi,

Could anyone help me with a reugular expression for a UK mobile phone
number?

So far I have tried this but with no success

<snip>
$regexp = "/^447[0-9]{9}$/";
if(!preg_match( $regexp, $_POST[mobile_number] )){
$error = "Invalid Mobile Number";
</snip>

The number nust be 11 numbers long, be all numbers, have no spaces and begin
with 447.

Any help would be greatly appreciated...

attached mail follows:

Do you even need a regex?

What about

if (strlen($_POST['mobile_number']) != 11 &&
substr($_POST['mobile_number'],0,3) != 447)
{
$error="Invalid Number";
}

This doesn't verify that the portion following 447 is also a number.

eg. 4474567X901

11 minus 3 = 8?

You're matching 447, then 9 numbers after that...bringing the total
numbers to 12, not 11.

$regexp = "/^447\d{8}$/";

That expression looks perfectly valid for the conditions you have stated
(given that you meant 12 digits, not 11, which would be correct for UK
mobiles). There must be some other kind of error.

As a first step, I suggest you do a var_dump($_POST['mobile_number']) to
make sure it's exactly what you think it should be. (And, yes, you should
be quoting the index to the $_POST[] array.)

However, if you mean genuine mobiles, and not pagers or other follow-me type
numbers in the UK 07 range (or even completely unallocated parts of it!),
then you need to refine that pattern a bit; this should do:

$regexp = "/^447[7-9][0-9]{8}$/";

Hi,

Does anybody have any depthful knowledge of the SimpleXML extension in
PHP5?..

More accurately, do you know if the simpleXml->xpath() method uses DOM,
SAX or some other method of parsing a loaded XML document?

I ask because I am trying to parse arbitrary XML documents as efficiently
as possible (avoiding DOM).

SimpleXML uses the same stuff as DOM in the backend. So you won't gain
any efficency using SimpleXML

Hi,

How can i add new items to an array without using an index.
Normally (single dimension) you can do: Arr[]="xxxxx" and this item is
added to the array, but what if i have subitems like:
Arr[]['name']="arnold"; Arr[]['address']="street".
This last example doesnt work and i think there will be an easy solution but
who can tell me this?

You mean like this...

    $sub = array
    (
        'name' => 'Ahhhhhnold',
        'address' => '123 Someplace Nice',
    );

$bigArray[] = $sub;

try $Arr[] = array('name' => 'arnold', 'address' => 'street');

Something else that will work is the following:

$arrPt =& $Arr[];
$arrPt['name'] = 'bob';
$arrPt['address'] = 'wherever';

thnx,
Chris

attached mail follows:

How come you guys always go for the simplest answer? why not do something like,

$num = count($arrPt);
$arrPt[$num]['name'] = "Figntin' Bob";
$arrPt[$num]['address'] = "Under the Broad Street Bridge";

Live a little...

Hi!
I need someone who is very good with maths to help me
with this, unfortunatly I suck at maths so that
someone can not be me. Ironically before I started my
first computer course years back I asked the
instructer if "learning computers needed a lot of
maths...she said 'no, just basics'"..that aint really
true is it? :-D

Anyway, I have 2 scripts, one that resizes an image
according to the height and width i specify and
another that cuts a w=90 h=120 thumb from *within* an
image according to the x and y parameters I send it.
This functionality is distributed in 2 scripts.

Heres my maths problems in 2 parts:

Problem 1)
I need to scale down an image (eg: example.jpg) to
height of 120 pixels while maintaining the images
proportions.

eg:
if i have an image of (height and width) 800x600 what
would the dimensions be if the height was 120?

usually for resizeing I just do something like this:

if($image_height > 400)
{$image_height=$image_height / 2;
$image_width=$image_width / 2;}

which gets me a pretty decent image....but now I need
an image no more than 120px in height with a
proportionate width.

Problem 2)
After getting the above image now I need the x and y
parameters to cut a h120 x w90 thumb *from the center
of the image*

eg: if from problem 1 the result is an image of 120 x
160 then x=35 and y=125 (I think, i told you i suck at
maths.. :-D )

Anyone up to the challenge? or just want to help a
poor person with some maths?

Thanks in advance,
Mag

Problem 1)

$h_1 = 600;
$w_1 = 800;

$h_2 = 120;
$w_2 = $w_1 * ($h_2 / $h_1);

Problem 2 a)

Assuming you're wanting the central portion of the original image (which
I think you are from what you've written)

$h_1 = 600;
$w_1 = 800;

$h_2 = 120;
$w_2 = 90;

$x = ($h_1 - $h_2) / 2;
$y = ($w_1 - $w_2) / 2;

Problem 2 b)

If you're in fact trying to get the central portion of the new thumbnail

$h_1 = 600;
$w_1 = 800;

$h_2 = 120;
$w_2 = $w_1 * ($h_2 / $h_1); // need to have the correct thumbnail
width to start from

$x = ($w_2 - 90) / 2;
$y = 0; // because the image is only 120px high

Hope this helps

Cheers

Good questions.. Here's some stuff to play with:

Proportions can be figured out by doing cross multiplication. Say
you're trying to figure out percentages, do something like this:

x 75
----- x -------
100 185

Multiple cross ways and you get:

185x = 7500

Divide both sides by 185 to get just an "x = " and you get 40.54. 75
is 40.54% of 185.

You can use this to get your proportions for images too. It doesn't
have to be 100 at the bottom of that one side. Say you have an image
that's 1275 x 852 and you want to create a 120 x ???? Thumbnail.

1275 w 120 w
------ x -------
852 h x h

1275x = 102240 (1275 times x = 120 times 852)

Divide both sides by 1275 and you get:

X = 80.19.... Which you might round to 80.

So a 1275 x 852 image scale down to 120 x 80.

Easy, right? :)

This one's even easier. Using the same 1275 x 852 image:

1275 w - 120 w = 1155 (difference in widths)

1155 / 2 = 577.5 (578 rounded let's say). That's how much space you'll
have on either wide width-wise. That'll give you a 120w "center cut"

Do the same with the height:

852 - 90 = 762

762 / 2 = 381

So your top-left pixel to start cutting would be at 578 x 381.

Try it out and let us know how it worked.

Very helpful indeed. Until today I had used softwares like Photoshop
to get the exact proportion rate. This really works, thank you guys.

Hi.

I'm setting up a credit card payment app. When I send the information
through the form I get a result similar to this:

NOT CAPTURED:000000:428930479495:NA:1015:9755676331042890:1:1::::

This is the only data in the result page.

I have never done parsing, and I have no idea of how to get this
information inerted into variables.

The result data is a series of data separated by ':'

Could anyone please give me a hint as of where to look for information
on how to do the parsing, or a short sample script?

And if also someone knows of a good reference manual on scraping and
parsing with PHP, I'd appreciate it.

Thx

Carlos.

Hi again guys, :-)
Thanks to the educated (and excellient) help of Chris
and trevor I am now getting proportionate thumbs
(which was "problem 1", remember? )

Heres the code that i am using, if it may help anyone
else:

** code start **
$src_img = imagecreatefromjpeg("tgp1.jpg");
$img_dim = getimagesize("tgp1.jpg");

$h_1 = $img_dim[1];
$w_1 = $img_dim[0];

$dst_h = 120;
$dst_w = $w_1 * ($dst_h / $h_1);

$dst_img = imagecreatetruecolor($dst_w,$dst_h);
$src_w = imagesx($src_img);
$src_h = imagesy($src_img);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$dst_w,$dst_h,$src_w,$src_h);
// problem 1 solved till here
** code end **

Then i am trying to work with problem 2, instead of
starting all over again from the beginning of getting
the images dimensions etc I am continueing and trying
to get it straight from the above like so:

** code start problem 2**
$dst_w = ($dst_w - 90) / 2;
$dst_h = 0; // because the image is only 120px high

imagecopyresampled($dst_img,$src_img,0,0,0,0,$dst_w,$dst_h,$src_w,$src_h);

ImageJPEG($dst_img,'test.jpg');
echo "<img src=test.jpg><br>The bitch works!";
** code end problem 2 **

When i check the output I am only getting the first
parts output... is what i am doing even possible? or
do I have to do everything from the start for problem
2 (eg: read from disk, calculate dimensions etc)

Thanks,
Mag

My interpretation of Problem 2 before was that you wanted to get a 120w

You seem to be working off of the adjusted height.

Sorry, I didn't noodle all the way through this one, what I am missing?

Hi Trevor,

Sorry, am just a bit confused myself mostly because I
am using a third party script to clip the 120x90 part
out of the image...understanding the way the script is
written is a little frustrating as it was written for
something else and I am trying to adopt it.

if you want to try your hand at it tell me and i'll
zip up the script and send it to you.

Thanks,
Mag

No worries. But here's my thought:

1. You start with an image, getting it's current (original) proportions
2. You figure out the width and height proportions to resize it down to
something small
3. Resize image (creating a new image.. At least to send to the browser
if not in a file separate from the original..whichever works for you)
4. Take the original image (not the resized one) and clip a little
section out of the middle of it to use as a thumbnail as well (or
whatever).

I think this is what you are aiming for because there are two theories
regarding thumbnails:

A. Take the original and scale it down.. But this can create an image
that doesn't look like anything (if the original had a lot of detail
and/or was huge)
B. Take a portion of the original (like someone's face out of a scene
that really shows their whole body). This can sometimes be fun because
it shows a small portion of an image that can make people curious.. Like
"What the heck is that I'm seeing? I have to see more!"

I'm not sure if that's what you were planning to do or not. Why don't
you detail your intentions and then maybe we can figure out how to best
do that.

I think you've a couple of problems with your second problem (problem
problem problem).

First of all, you're setting $dst_h to 0, which gives you a height of 0
- IIRC that's not what you wanted :)

You should be setting that $dst_h = 120 as you always want it to be 120px

I reckon that your code should look more like this:

<?php

// assuming that we're creating two thumbnails, one has h=120, w=?, the
second has h=120, w=90
// we'll also assume that the original has h=600, w=800

$src_img = imagecreatefromjpeg("tgp1.jpg");

$src_h = imagesy($src_img); // 600
$src_w = imagesx($src_img); // 800

$dst_h = 120;
$dst_w = $src_w * ($dst_h / $src_h);

$dst_img = imagecreatetruecolor($dst_w,$dst_h);

imagecopyresampled ($dst_img, $srcImage, 0, 0, 0, 0, $dst_w, $dst_h, $src_w, $src_h);

// so far so good, now, lets save the file
imagejpeg($dst_img, 'test.jpg');

unset($dst_img);

// time for problem 2

// first we need a h=120, w=90 image

// image size for h=120, w=90 thumbnail
$dst_h = 120;
$dst_w = 90;

$dst_img = imagecreatetruecolor($dst_w, $dst_h);

// we will be copying to the top left corner of the new thumbnail
$dst_x = 0;
$dst_y = 0;

// now, let's find the top-left offset from the larger original image
$src_x = ($src_h - $dst_h) / 2;
$src_y = ($src_w - $dst_w) / 2;

// no need for imagecopyresampled as we'll be doing 1-1 pixel copying here

imagecopy ($dst_img, $src_img, $dst_x, $dst_y, $src_x, $src_y, $src_w,
$src_h);

// so far so good, now, lets save the file
imagejpeg($dst_img, 'test2.jpg');

unset($dst_img);

?>
<img src="test.jpg" /><img src="test2.jpg" />

------------

Hope this helps (although I haven't tested it)

Cheers

Hey Chris,
Thanks for replying.

Dont worry about it, I got so p*ssed that I just
striped the whole thing down to pretty much just the
imagecopyresized() function, fiddled around with it to
see how it works and got the sh*t working. The good
thing now is I understand a bit better how the
function works and thanks to you and Trever I learnt
how the first problem works too, not a bad day at all
if I say so myself.

Working on other parts of the scripts now so have not
uploaded the working parts but if you would like to
see it working, just reply.

Cheers,
Mag

I am also trying to do this. Dovecot is the default IMAP server on
FC2. I haven't had time to try it yet, but here is a link I found
about compiling PHP with dovecot:

http://www.dovecot.org/list/dovecot/2004-July/004282.html

I should have a chance to try later today and will let you know if I
have any luck.

Hi,

I am working on setting up a VPOS system, and I need to read the
results of sending the CC information to the bank.

When sending the form I am doing it with HTTPS port 443 with POST
method in my form and application/www-form-urlencoded

When I get the results of my submission I get another https URL .
Since I send the form using POST, I get no params in the URL. BTW, GET
is not supported.

What I need to do is be able to read the results of that page so I can
parse them and have the machine understand what was the result of the
credit card charge.

Any idea of how I can get to save the results of that page into a variable?

Thanks!

Carlos.

You can either use Curl functions or fsockopen with OpenSSL support,
depending on what is available on your system.

You may want to try this HTTP client class that supports submitting POST
requests via SSL as you need in a very simple way and it figures which
PHP extension to use to send your requests and collecting the responses
if possible with your PHP setup.
