How to pass a PHP array to a JavaScript function?

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.

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:

filter_none

edit
close

play_arrow

link
brightness_4
code

<?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>

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:













                                    filter_none




                                    edit

                                    close




                                    play_arrow




                                    link

                                    brightness_4

                                    code
                                




















<?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>
