A slightly modified (5 times smaller, 60 times faster) version of subdivizion's code:
<?php
function check_gsm( $str )
{
$arr = array( 6922, 6932, 6952, 6953, 6959, 6972, 6973, 6974, 6976, 7013 );
foreach( str_split( $str ) as $char )
{
$i = ord( $char );
if( $i > 127 && ! in_array( $i, $arr ) ) return false;
}
return true;
}
?>
