How to append a string in PHP ?

We have given two strings and the task is to append a string str1 with another string str2 in PHP. There is no specific function to append a string in PHP. In order to do this task, we have the this operator in PHP:

Using Concatenation assignment operator (“.=”): The Concatenation assignment operator is used to append a string str1 with another string str2.

$x .= $y

PHP

filter_none

edit
close

play_arrow

brightness_4
code

<?php
// PHP program to append a string 
  
  
// function to append a string 
function append_string ($str1, $str2) {
      
    // Using Concatenation assignment
    // operator (.=)
    $str1 .=$str2;
      
    // Returning the result 
    return $str1;
}
  
// Given string
$str1 = "Geeks"
$str2 = "for"
$str3 = "Geeks"
  
// function calling
$str = append_string ($str1, $str2);
$str = append_string ($str, $str3);
