How to pass a PHP array to a JavaScript function?

  • Last Updated : 01 Aug, 2021

Passing PHP Arrays to JavaScript is very easy by using JavaScript Object Notation(JSON).

Method 1: Using json_encode() function: The json_encode() function is used to return the JSON representation of a value or array. The function can take both single dimensional and multidimensional arrays.

Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course. Now at it's lowest price ever!

Steps:

  • Creating an array in PHP:
    <?php
    $sampleArray = array(
            0 => "Geeks", 
            1 => "for", 
            2 => "Geeks", 
        );
    ?>
    
  • Using json_encode() function to retrieve the array elements
    var passedArray = <?php echo json_encode($sampleArray); ?>

Example:






<?php
     
// Create an array
$sampleArray = array(
    0 => "Geeks", 
    1 => "for", 
    2 => "Geeks", 
)
?>
   
<script>
  
// Access the array elements
var passedArray = 
    <?php echo json_encode($sampleArray); ?>;
       
// Display the array elements
for(var i = 0; i < passedArray.length; i++){
    document.write(passedArray[i]);
}
</script>

Output:

Method 2: Using PHP implode() function: The implode() is used to join the elements of an array. The implode() function is the alias of join() function and works exactly same as that of join() function.
The implode() function is used to build a string that becomes an array literal in JavaScript. So, if we have an array in PHP, we can pass it to JavaScript as follows:

var passedArray = <?php echo '["' . implode('", "', $sampleArray) . '"]' ?>;

Example:




<?php
  
// Creating a PHP Array
$sampleArray = array('Car', 'Bike', 'Boat');
  
?>
  
<script type="text/javascript">
   
// Using PHP implode() function
var passedArray = 
    <?php echo '["' . implode('", "', $sampleArray) . '"]' ?>;
   
// Printing the passed array elements
document.write(passedArray);
   
</script>

Output:

Car, Bike, Boat
