Parse a String

[Anon]

hi !

i'm starting with php and i would like do a simple function (must work with php3). If the String contains a specific char '|' then it return all after this char without it. If this String doesn't contain this char, all the String is return.
I tried this code but it doesn't work !

<?
function filter($titre){
$delimiteur=("|");
$index=strrpos($titre, $delimiteur);

if(is_string($index) && !$index){
return($titre);
} else {
return(substr(strstr($titre,$delimiteur), 1));
}
}

?>

<?
print(filter("1|title1"));
print(filter("2|title2"));
print(filter("title3")); // without char |
?>

I found the (is_string($index) && !$index) code in a tutorial but i think it doesn't work...
Do you have the solution ?

Thanks,
Eric

ya, use regular expressions.

<?
$myString = "something|something else";
if (preg_match('/.|+(.)/s',$myString,$txtArray)) {
$myString = $txtArray[1];
}

echo $myString;
?>

function thefunctionname($thestring)
{
$strings = explode('|',$thestring);
If (is_string($strings[1])) { $final = $strings[1]; } else { $final = $thestring; }

return $final
}

Oops... forgot to escape that damned 'OR' operator you were using as a delimeter.

Sorry about that, here's the working version

<?
$myString = "something|something else";
if (preg_match('/.|+(.)/s',$myString,$txtArray)) {
$myString = $txtArray[1];
}

echo $myString;
?>

Don't understand... don't know where is the expecting 'STRING' ?
