Regular expressions: Match a repeating string

[pastet89]

Hello all!
I have that string:

$str = "blablabla 00 00 bla 11 blablabla 22 blablabla 33 33 33 33 blabla 44 bla";

and I want to get that output from it:

Array
(
    [0] => Array
        (
            [0] => bla 00 00 bla
            [1] => bla 11 bla
            [2] =>  bla 22 bla
            [3] => bla 33 33 33 33 bla
        )
 
    [1] => Array
        (
            [0] => 00 00
            [1] => 11
            [2] => 22
            [3] =>  33 33 33 33 
        )
 
)

The [0] array is not important for me. I know it always will contain the whole matches. But what I need is in the second array [1], to get all the numbers, REPATING OR NOT. I use that code:

preg_match_all("#" . "bla([[:space:]]*[0-9]{2}[[:space:]]*)*bla" . "#", $str, $ma4);
print_r($ma4);

and what I get is:

Array
(
    [0] => Array
        (
            [0] => blabla
            [1] => bla 00 00 bla
            [2] => blabla
            [3] => bla 22 bla
            [4] => blabla
            [5] => blabla
        )
 
    [1] => Array
        (
            [0] => 
            [1] => 00 
            [2] => 
            [3] =>  22 
            [4] => 
            [5] => 
        )
 
)

Please, help me to get the code I need!

I'd probably try something like this (untested):

'/\b([0-9]{2})\b(\s+\1\b)*/'

nope, Here is the output:

Array
(
    [0] => Array
        (
            [0] => 00
            [1] => 00
            [2] => 11
            [3] => 22
            [4] => 33
            [5] => 33
            [6] => 33
            [7] => 33
            [8] => 44
        )
 
    [1] => Array
        (
            [0] => 00
            [1] => 00
            [2] => 11
            [3] => 22
            [4] => 33
            [5] => 33
            [6] => 33
            [7] => 33
            [8] => 44
        )
 
    [2] => Array
        (
            [0] => 
            [1] => 
            [2] => 
            [3] => 
            [4] => 
            [5] => 
            [6] => 
            [7] => 
            [8] => 
        )
 
)

Works for me:

PHP Code:

<?php
$str = "blablabla 00 00 bla 11 blablabla 22 blablabla 33 33 33 33 blabla 44 bla";
preg_match_all('/\b([0-9]{2})\b(\s+\1\b)*/', $str, $matches);
echo "<pre>".print_r($matches[0], 1)."</pre>";

Output:

Array
(
    [0] => 00 00
    [1] => 11
    [2] => 22
    [3] => 33 33 33 33
    [4] => 44
)

Wow, it really seems to work!
But can you help me a little bit further, because that was just a simple example of what am I trying to do and now I tried to apply it to my project and I coludn't...
OK, I have that string:

<td>team1</td>
<td><img src='/img/b.png' class='redYellowCard' alt='' \> team2</td>
<td><img src='/img/b.png' class='redYellowCard' alt='' \> <img src='/img/b.png' class='redCard' alt='' \> team3</td>

The array I want to get is:

   Array
(
    // the whole matches
    [0] => Array
        (
            [0] => team1
            [1] => <img src='/img/b.png' class='redYellowCard' alt='' \> team2
            [2] => <img src='/img/b.png' class='redYellowCard' alt='' \> <img src='/img/b.png' class='redCard' alt='' \> team3 
        ) 
    //the images independently of their number - 0, 1, 2, 3 etc. For the simple expample, I give the maximum of 2 
    [1] => Array
        (
            [0] => 
            [1] => <img src='/img/b.png' class='redYellowCard' alt='' \>
            [2] => <img src='/img/b.png' class='redYellowCard' alt='' \> <img src='/img/b.png' class='redCard' alt='' \>
        )
    //the teams
    [2] => Array
        (
            [0] => team1
            [1] => team2
            [2] => team3
        )
 
)

First I tried that one:

preg_match_all(
"#" . "(<[a-z][a-z0-9]*[^<>]*>)" . "([[:space:]]*\<img src='/img/b.png' class\='[redYlowCard]+' alt\='' /\>[[:space:]]*)*" . "([a-z0-9]+)" . "(</[a-z][a-z0-9]*[^<>]*>)"
)

and it was matching only zero to maximum one image.
Now I try to apply your code in that way:

preg_match_all(
"#" . "(<[a-z][a-z0-9]*[^<>]*>)" . "/\b<img src='/img/b.png' class\='[redYlowCard]+' alt\='' /\>\b(\s+\1\b)*/" . "([a-z0-9]+)" . "(</[a-z][a-z0-9]*[^<>]*>)"
)

and there is no match at all!
Can you help me to apply it properly?

I would agree with the reply you got at PHPBuilder that you use the DOM class/functions for this.

... I have just fixed it without them!!!
Thanks a lot for the initial help!!!
Here is my code:

((?:[[:space:]]*<img src='/img/b.png' class\='[redYlowCard]+' alt\='' /\>?[[:space:]]*)*)
