Make sure that the parameter you are passing to the ord function is a string.
<?php
$num = 12345;
// Incorrect usage of square bracket notation
if(ord($num[0]) == 0) {
echo "Not a valid ASCII character";
}
// Using the substr method will account for any data type
if(ord(substr($num,0,1)) == 0) {
echo "Not a valid ASCII character";
}
?>
