<?php
$strings = array('string1' => "

arf12", 'string3' => '
');
foreach ($strings as $name => $testcase) {
if (ctype_space($testcase)) {
echo "The string '$name' consists of all whitespace characters.
";

echo "The string '$name' does not consist of all whitespace characters.

ues have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string contain-
ing the decimal digits of the integer.
