preg_match_all does not return expected result

[adamjblakey]

Hi,

I seem i seem to have a problem with this:[PHP]
for($i=1;$i<7;$i++) {
$content = file_get_contents('http://www.web.co.uk/d.asp?ID='.$i);
preg_match_all($email_match_regex, $content, $matches);
foreach($matches[1] as $index => $value) {

print $index[1];
}
}[/PHP]
I am getting the following errors which i cannot fix:

Warning: Invalid argument supplied for foreach() in /home/ee/public_html/test.php on line 13
Notice: Undefined variable: email_match_regex in /home/ee/public_html/test.php on line 11

Any Ideas?

Hey there adam!

PHP is saying you haven't got a variable named email_match_regex?

Check to see if you do!
Regards.

Hi Adam,

The problem is in the follwoing line:
[PHP]$content = file_get_contents('http://www.web.co.uk/d.asp?ID='.$i);[/PHP]file_get_contents() will fetch raw data, ie the page will not be parsed.
And becasuse its not parsed, the filename param given must match to the filename exactly.

Consequently, because $content is empty, you get a whole load of problem further down your script.

My question to you: should you be trying to take data from other websites?

This is absolutely not true!

The error originates in the absence of the regular expression pattern variable in line 11. Since there is no result, there is also no $matches variable, resulting in the error on line 13.

The content of variable $content has nothing to do with this. Even if it is empty the preg_match_all results in an array containing one or more empty arrays.

My question to you: should you be trying to take data from other websites?

And please: no missionaries. This is not the place to question our members on their reason for using a pretty-standard PHP function. There is no indication whatsoever that it is morally unjust or illegal what our member adamjblakey is doing! So don't even hint at that!

Thank you for that ronverdonk, i have now done this based on your comments, which does not bring any errors back but does not bring any results but i know there should be.

[PHP]<?php

$email_match_regex = "^([_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.[a-z]{2,4})$^";

for($i=1;$i<7;$i++) {

$content = file_get_contents('http://www.web.co.uk/details.asp?ID='.$i);

preg_match_all($email_match_regex, $content, $matches);

foreach($matches[1] as $index => $value) {

print $index[1];

}

}

?>[/PHP]

[ronverdonk]

Please explain what the reg exp is supposed to filter.
