ctype_space

(PHP 4 >= 4.0.4, PHP 5)

ctype_space -- Check for whitespace character(s)

Description

bool ctype_space ( string text)

Returns TRUE if every character in text creates some sort of white space, FALSE otherwise. Besides the blank character this also includes tab, vertical tab, line feed, carriage return and form feed characters.

Example 1. A ctype_space() example

<?php
$strings
= array('string1' => "\n\r\t", 'string2' => "\narf12", 'string3' => '\n\r\t');
foreach (
$strings as $name => $testcase) {
    if (
ctype_space($testcase)) {
        echo
"The string '$name' consists of all whitespace characters.\n";
    } else {
        echo
"The string '$name' does not consist of all whitespace characters.\n";
    }
}
?>

This example will output :

The string 'string1' consists of all whitespace characters.
The string 'string2' does not consist of all whitespace characters.
The string 'string3' does not consist of all whitespace characters.
