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

php




<?php
// PHP function to illustrate the
// use of IntlChar::isJavaIDPart()
 
// Input control character codepoint value
var_dump(IntlChar::isJavaIDPart("\n"));
  
// Input string codepoint value
var_dump(IntlChar::isJavaIDPart("Report Bug"));
   
// Input int codepoint value
var_dump(IntlChar::isJavaIDPart("3 "));
 
// Input string codepoint value
var_dump(IntlChar::isJavaIDPart("R"));

var_dump(IntlChar::isJavaIDPart("33.44"));
   
// Input int char an identifier
// of codepoint value
var_dump(IntlChar::isJavaIDPart("\u{007F}"));

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

             "Geeks",
        );
   
// For loop condition to check
// each character through function
foreach ($arr as $val) {
       
    // Check each element as code point data
    var_dump(IntlChar::isJavaIDPart($val));
}
?>

Output:
