php split command

Something like this..you may have to tweak it.

<?php
$inputstring="Big Medium(20,2) Small(25,3)";
$newstring="";
$instrlen=strlen($inputstring);
$inparens=false;

for ($i=1; $i<$instrlen; $i++)
  {
       //get a char
        $c=substr($inputstring,$i,1);

        //eval the char
       switch ($c) {
           case '(':
                //started the ( section; eat everything until we find a )
                $inparens=true;
                break;
           case ')':
                //found ) so stop eating chars
                $inparens=false;
                break;
           default:
                //do this otherwise
               if ($inparens) {
                   //do nothing, i.e. eat the chars
                   //this isn't necessary, but here for clarity
               }
               else {
                   //we aren't in parens so continue buiding our new string
                   $newstring=$newstring . $c;
               }
       }//switch
  }//for
?>

Select allOpen in new window

When this is done $newstring should contain the string without the ( ) and anything between them.

the following will split it at every space; you'll need to set that to an array
split(" ", $newstring);

However it says the above is deprecated.

I highly suggest that you do a little reading when trying to do these. A good reference is found here:

Here we go now tested:
<?php

$new=strtolower(preg_replace("/\(.*\)/U","","Big Medium(20,2) Small(25,3)"));
print($new);
$array=explode(" ",$new);
print_r($array);

?>
