How to print array in Php

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

print_r() function

Example: (Recommended learning:PHP video tutorial)

Run this example output:

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

var_dump() function

Example:

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.
