Picky explode()

Tree · 06-15-2008, 09:48 PM

I was browsing another forum earlier today and came across someone who wanted to split a string into an array. That's a fairly simple task with explode(). But they also wanted anything in between brackets to be left alone.

I came up with a solution that works fine, but I'm fairly certain there's a better way to do it. Here's what I've got.

PHP Code:


			
<?php
$string = "501,Red_Potion,Red Potion,0,50,,70,,,,,0xFFFFFFFF,7,2,,,,,,{ itemheal rand(45,65),0; },{},{}";
echo '<pre>';
print_r(picky_explode($string));
echo '</pre>'; 

function picky_explode($string) {
    $array = explode(',',$string);
    $array_size = count($array);
    foreach ($array as $key => $value) {
        $newvalue = '';
        // The code below combines any array elements between a pair of brackets {}
        if (strpos($value,'{') !== false) {
            for ($i = $key;$i<=$array_size;$i++) {
                $newvalue .= ",".$array[$i];
                if (strpos($array[$i],'}') !== false) {
                    for ($x=$i;$x>$key;$x--) {
                        $kill[] = $x;
                    }
                    break;
                }
            }
        } else {
            $newvalue = $value;
        }
        $array2[] = str_replace(",{", "{",$newvalue);
    }
    foreach ($kill as $value) {
        unset($array2[$value]);
    }
    foreach ($array2 as $value) {
        $final_array[] = $value;
    }
    return $final_array;
}
?>

Any ideas?
