i have a string that looks something like this:
-1--3--8--22--550--1028-

how to make it an array like this:
0 =1,
1 =3,
2 =8,
3 =22,
4 =550,

<?php

$string = '-1--3--8--22--550--1028-';
$array = explode( '--', trim( $string, '-' ) );
var_dump($array);

?>

Will do the trick.

Sorry, can't help you with the reg ex. But Google should provide lot's of
info.

Just found out...

preg_split("%-%",$string_to_search,-1,PREG_SPLIT_NO_EMPTY);

Thank you for your time.

Thank you for your time.

preg_split("/-+/", $string_to_search) is a somewhat more orthodox
solution.

$string = "-1--3--8--22--550--1028-";

if(ereg
("-([0-9]{1})--([0-9]{1})--([0-9]{1})--([0-9]{2})--([0-9]{3})--([0-9]{4})-",
$string, $regs)){
$array_set = array_splice($regs,1);
print_r($regs);
print_r($array_set); // <- This is the output requested.
}

print_r($regs);
print_r($array_set); // <- This is the output requested.
}

But a lot more undynamic & slower, I'd suggest using Chung's solution. It's
the fastest and the easiest altered.
