PHP program to check if a string has a special character
To check if a string has a special character, the PHP code is as follows;
Example
<?php
function check_string($my_string){
$regex = preg_match('[@_!#$%^&*()<>?/|}{~:]', $my_string);
if($regex)
print("String has been accepted");
else
print("String has not been accepted");
}
$my_string = 'This_is_$_sample!';
check_string($my_string);
?>Output
String has not been accepted
Above, a function named ‘check_string’ is defined, that takes a string as its parameter −
$my_string = 'This_is_$_sample!';
Use regular expression to check if a string has a special character. If there is a special character, a specific message is printed. Outside the function, the string is defined, and the function is called by passing the string as parameter −
function check_string($my_string){
$regex = preg_match('[@_!#$%^&*()<>?/|}{~:]', $my_string);
if($regex)
print("String has been accepted");
else
print("String has not been accepted");
}
