# ctype_graph

(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.

예 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.
