Hi I am trying to replace , with | from a long string with in braces [] but the following seems to be failed.

Here is the string.

ID: 3a0dd504341fb10a055xxxxxx, time: Wed Feb 01 12:54:39 EST 2012, client: 10.192.34.13, user: User [ID: 1456xcvererwe, session ID: sdfweerwer234325433 ], action: USER_ACTION_ITEM, action id: 36014, result: FAIL, reason: USER_EXCEPTION, arguments: [abcd, test12 , testing ]

Here is what I want as output.

ID: 3a0dd504341fb10a055xxxxxx, time: Wed Feb 01 12:54:39 EST 2012, client: 10.192.34.13, user: User [ID: 1456xcvererwe | session ID: sdfweerwer234325433 ], action: USER_ACTION_ITEM, action id: 36014, result: FAIL, reason: USER_EXCEPTION, arguments: [abcd | test12 | testing ]

I tried following

$text = preg_replace("/(^[)(.*)(])/U","|",$text);

    Use preg_replace_callback

    $text = 'ID: 3a0dd504341fb10a055xxxxxx, time: Wed Feb 01 12:54:39 EST 2012, client: 10.192.34.13, user: User [ID: 1456xcvererwe, session ID: sdfweerwer234325433 ], action: USER_ACTION_ITEM, action id: 36014, result: FAIL, reason: USER_EXCEPTION, arguments: [abcd, test12 , testing ]';

function rep($r){
    return "[". preg_replace('/\s*,\s*/',' | ', $r[1]). "]";
}
echo preg_replace_callback('/\[([^\]]+)\]/i', 'rep', $text);
