PHP Ctype (Character type) functions

PHP Ctype (Character type) capacities: Here, we will find out about the character type (Ctype) works in PHP. Ctype capacities PHP gives a portion of the implicit capacities, which are utilized to check the characters in the string, for example, to check whether a string contains the characters of explicit sorts. Rundown of the Ctype capacities in PHP Here, is the rundown of the PHP Ctype capacities… 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_lower() - Checks whether given string contains every single lowercase character. ctype_upper() - Checks whether given string contains every single capitalized character. ctype_punct() - Checks whether given string contains all accentuation characters. ctype_xdigit() - Checks whether given string contains every single hexadecimal digit. ctype_print() - Checks whether given string contains every single printable character. ctype_graph() - Checks whether given string contains every single printable character anticipate space. 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"); ?> Output 1 1 1 1 1 1 1 1 1 1 1
