php has two functions for printing arrays: print_r() function and var_dump() function

How to print array in Php

print_r() function

Example: (Recommended learning: PHP video tutorial)

<?php 
  $arr_test =
array(1, 2, 3);
 print_r($arr_test);
?>

Run this example output:

Array
(  
[0] => 1      
[1] => 2     
[2] => 3
)

var_dump() function

Example:

<?php
$arr_test = array(1, 2,
3);
var_dump($arr_test);
?>

Run this example output:

array(3) 
{  
[0]=> int(1)
[1]=> int(2)
[2]=> int(3)
}

The var_dump() function is used the same as the print_r() function. However, the var_dump() function is more powerful than print_r(). It can print multiple variables at the same time and give the type information of the variables.
