$a = '88';
$b = '88 8888';

echo (int)$a;
echo (int)$b;

as expected, both produce 88. Anyone know if there's a string to int function that will work for $b's value and produce 888888? I've googled around a bit with no luck.

Thanks

You can use the str_replace when you declare your variable $b like that :

$b = str_replace(" ", "", '88 8888');
echo (int)$b;

Or the most beautiful solution is to use intval :

$b = intval(str_replace(" ", "", '88 8888');
echo $b;

If your value '88 888' is from an other variable, just replace the '88 888' by the variable who contains your String.
