To James holwell:
Maybe your function was more strickt, but profides FALSE to any numeric string that wasnt written in
the English/American notition. To enable a person to use the both the English/American and the rest
of the world's way:
<?php
function my_is_numeric($value)
{
return (preg_match ("/\A(-){0, 1}([0-9]+)((,|.)[0-9]{3, 3})*((,|.)[0-9]){0,
1}([0-9]*)\z/" ,$value) == 1);
}
?>
Other than that, i'd recommend using yours, if it works (i havent tested either yours or mine)
By using mine, there might be a slight chance to not being able to do calculations with the numeric
string if it's not the English/American way.
