ctype_space
(PHP 4 >= 4.0.4)
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.
