What is the php print array function?
php has two functions for printing arrays: print_r() function and var_dump() function
The print_r() function is used to print variables and display them in a more understandable form.
var_dump() function is used to output relevant information about variables.
var_dump() function displays structural information about one or more expressions, including the type and value of the expression. Arrays will expand values recursively, showing their structure through indentation.
print_r() function
Example:
<?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.
