Question

I got just a test pattern here, but it does disallow spaces.

$myarray[]='s s';
if (preg_match('/[^\d\w\(\)\[\]\.\-]+/',$myarray)>0) echo 'yes';

This does nothing, but

$test='s s';
if (preg_match('/[^\d\w\(\)\[\]\.\-]+/',$test)>0) echo 'yes';

This works fine…
I dont understand why it doesn’t work with my array?

preg_match doesn’t accept an array as input, just a single string. You’d need to do something like…

$matched = no;
foreach($myarray as $x) {
    if (preg_match('/[^\d\w\(\)\[\]\.\-]+/',$x)>0) $matched = true;
}
if($matched) echo 'yes';

To do it in one step:

function preg_match_any($regex,$array) {
    foreach($array as $x) {
        if (preg_match($regex,$x)>0) return true;
    }
    return false;
}

//Then to call it just something like:
if (preg_match_any('/[^\d\w\(\)\[\]\.\-]+/',$myarray)) echo 'yes';
