CTYPE_CNTRL(3) 1 CTYPE_CNTRL(3)ctype_cntrl - Check for control character(s)SYNOPSIS
bool ctype_cntrl (string $text)
DESCRIPTION
Checks if all of the characters in the provided string, $text, are control characters. Control characters are e.g. line feed, tab, escape.
PARAMETERS
o $text
- The tested string.
RETURN VALUES

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.
";
}
}
?>
The above example will output:
The string 'string1' consists of all control characters.
The string 'string2' does not consist of all control 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.
