EXAMPLES
Example #1
A ctype_cntrl(3) example
<?php
$strings = array('string1' => "
", 'string2' => 'arf12');
foreach ($strings as $name => $testcase) {
if (ctype_cntrl($testcase)) {
echo "The string '$name' consists of all control characters.
";
} else {
echo "The string '$name' does not consist of all control characters.
