preg_match(_all)

[Aureole]

I'm using preg_match and preg_match_all on a file I got using file_get_contents. Sometimes it works fine and sometimes it just refuses to work.

 

Say the source of the web page I am using file_get_contents on has

 

               <tr>
                   <td>Played</td>
                   <td class="values">778</td>
                </tr>
               <tr>
                   <td class="col1 left">Earned</td>
                   <td class="col2">49 of 49</td>
               </tr>

 

I did a preg_match for <td class="values">(.*?)</td> i.e.

<?php preg_match('/<td class="values">(.*?)<\/td>/', $file, $result); ?>

and it worked fine but

<?php preg_match('/<td class="col2">(.*?)<\/td>/', $file, $result); ?>

didn't work.

 

Anyone have any ideas? The problem happens with both preg_match and preg_match_all, sometimes when I search for something it works fine and other times it doesn't... thanks.

Nobody have any ideas? This is really frustrating me.

Both your patterns work fine within the haystack you provided.

If it doesn't work the problem is coming from somewhere else, verify your content from file_get_contents to be what you think it is when you have these "problems"

maybe putting them all into one pattern wud help u better?

preg_match_all('@(<td\s+(?:class)?\s*=\s*"(.*)"\s*>(.*?)</td\s*>)@i',$file,$result);

 

which resulted in a print_r like so:

Array
(
    [0] => Array
        (
            [0] => <td class="values">778</td>
            [1] => <td class="col1 left">Earned</td>
            [2] => <td class="col2">49 of 49</td>
        )

    [1] => Array
        (
            [0] => <td class="values">778</td>
            [1] => <td class="col1 left">Earned</td>
            [2] => <td class="col2">49 of 49</td>
        )

    [2] => Array
        (
            [0] => values
            [1] => col1 left
            [2] => col2
        )

    [3] => Array
        (
            [0] => 778
            [1] => Earned
            [2] => 49 of 49
        )

)

 

which now ya can move array 2 & 3 into an array pair

$values=array_combine($resullt[2],$result[3]);

 

which will give you access to your vars as

$values['values']

$values['col1 left']

$values['col2']

I just did:

 

<?php
str_replace( "\n", "", $file );
str_replace( "\r", "", $file );
str_replace( " ", "", $file );
?>

 

...and that got rid of most of the problems, the rest of the problems were because the file I am opening is amazingly large and preg_match can only read so many bytes as far as I could find out.
