preg_replace 1

[jamesp0tter]

i'm stuck...

imagine i have:

 $whtv_var = "[aaaaa] bbb (ccccccccc) - dddd";

so, to get those lil letters, i use:

 $As = preg_replace("'\[(.*?)\] (.*?) \((.*?)\) - (.*?)'","\$1", $whtv_var);
 $Bs = preg_replace("'\[(.*?)\] (.*?) \((.*?)\) - (.*?)'","\$2", $whtv_var);
 $Cs = preg_replace("'\[(.*?)\] (.*?) \((.*?)\) - (.*?)'","\$3", $whtv_var);
 $Ds = preg_replace("'\[(.*?)\] (.*?) \((.*?)\) - (.*?)'","\$4", $whtv_var);

right ?
the thing is... $As will contain "aaaaadddd", $Bs will have "bbbdddd", $Cs "cccccccccdddd" and $Ds "dddd"... at least in my code..

do you see my problem ? why does \$4 appear everytime ?

Mostly it's because you're using preg_replace() when what you really want is preg_match().

Try this on for size:

<?php
$whtv_var = "[aaaaa] bbb (ccccccccc) - dddd";

preg_match ('/\[(.*)\] (.*) \((.*)\) - (.*)/',$whtv_var, $matches);

print '<pre>';
print_r ($matches);
?>

On my LAMP (RH9/2.0.48/4.0.11/4.0.17/4.3.4) box, I get the output:

Array
(
    [0] => [aaaaa] bbb (ccccccccc) - dddd
    [1] => aaaaa
    [2] => bbb
    [3] => ccccccccc
    [4] => dddd
)
