(PHP 4 >= 4.0.4, PHP 5)

ctype_graph -- Check for any printable character(s) except space

Description

bool ctype_graph ( string text)

Returns TRUE if every character in text is printable and actually creates visible output (no white space), FALSE otherwise.

Example 1. A ctype_graph() example

<?php
$strings
= array('string1' => "asdf\n\r\t", 'string2' => 'arf12', 'string3' => 'LKA#@%.54');
foreach (
$strings as $name => $testcase) {
    if (
ctype_graph($testcase)) {
        echo
"The string '$name' consists of all (visibly) printable characters.\n";
    } else {
        echo
"The string '$name' does not consist of all (visibly) printable characters.\n";
    }
}
?>

This example will output :

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