ctype_alnum() – Checks whether given string contains all letters in order or numbers.

ctype_alpha() – Checks whether given string contains all letters in order.

ctype_digit() – Checks whether given string contains all digits.

ctype_space() – Checks whether given string contains spaces (whitespaces, tab, new line and so forth).

ctype_cntrl() – Checks whether given string contains all control characters.

PHP Ctype capacities Example

<?php
	echo (ctype_alnum("Hello123")."\n");
	echo (ctype_alpha("Helloworld")."\n");
	echo (ctype_digit("01234")."\n");
	echo (ctype_space("\r\n \t")."\n");
	echo (ctype_lower("helloworld")."\n");
	echo (ctype_upper("HELLOWORLD")."\n");
	echo (ctype_punct("!@#~*&(){}")."\n");
	echo (ctype_xdigit("aaff01290")."\n");
	echo (ctype_print("Hello world!")."\n");
	echo (ctype_graph("Hello123!@#")."\n");
	echo (ctype_cntrl("\x00\x1F\x7F\r\n")."\n");
