note 33756 added to function.is-numeric
To verify if a char is an alphabetical char (and not a symbol) not do this:
//wrong because also a non alphabetical sympbol will pass the test
if(!is_numeric($char))
but try this...
function is_alphabetical($char)
{
$alphabetical = 'abcdefghijklmopqrstuvwxyz';
if(in_array($char,$alphabetical))
return true;
else
return false;
}
sorry for my ebglish.. I hope you'll undestand
