Hi, Looking for a one-liner to delete all empty elements in an array. I know I can do it with a foreach loop, but I'm hoping that I've missed an existing function in the manual which may already do this, or a simple one-liner to replace the foreach. <?php foreach($in as $k => $v) {

    if(empty($v)) {
        unset($in[$k]);
    }

} ?> --- Justin French http://indent.com.au

Though it's not really a one-liner: [code] while ($key = array_search('', $in)) unset($in[$key]); [/code] For more infos on array_seach(): http://www.php.net/array_search Daniel

A note I forgot to addi in my previous posting: You ought to think over what you consider "empty" since empty() would for example return true if the checked variable contained the integer 0 or the string '0'. My posted line of code recognizes only an empty string as "empty".
