Below programs illustrate the IntlChar::isJavaSpaceChar() Function in PHP:
Program 1:

php

<?php
// PHP function to illustrate the
// use of IntlChar::isJavaSpaceChar()

// Input control character codepoint value
var_dump(IntlChar::isJavaSpaceChar("\n"));

// Input control character codepoint value
var_dump(IntlChar::isJavaSpaceChar("\r"));

// Input string codepoint value with
// Capital and small letter
var_dump(IntlChar::isJavaSpaceChar("V"));

// Input int char an identifier
// of codepoint value
var_dump(IntlChar::isJavaSpaceChar("\u{00A0}"));

// Input symbolic space codepoint value
var_dump(IntlChar::isJavaSpaceChar(" "));

// Input symbolic codepoint value
var_dump(IntlChar::isJavaSpaceChar(" ^ "));

// Input string codepoint value
var_dump(IntlChar::isJavaSpaceChar("Bug"));

// Input int codepoint value
var_dump(IntlChar::isJavaSpaceChar("3 "));

?>

Output:

bool(false) 
bool(false) 
bool(false) 
bool(true) 
bool(true) 
NULL 
NULL 
NULL 

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)
bool(true)
bool(false)
NULL
bool(false)
