Program 2:

php

<?php
// PHP function to illustrate the
// use of IntlChar::isJavaSpaceChar()
 
// Declare an array with
// different codepoint value 
$arr = array("\\",
             " ", 
             "\n",
             " #",
             "\t",
        );
   
// For loop condition to check 
// each character through function
foreach ($arr as $val) {
       
    // Check each element as code point data
    var_dump(IntlChar::isJavaSpaceChar($val));
}
?>

Output:

bool(false)
