2 ways of printing an array in php

PHP provides two very useful functions that can be used to output a variable’s value recursively called print_r() and var_dump().

– Create An Array:

$my_array = array("elem_1","elem_2","elem_3");

– Using Print_r() function:

Print_r() can return its output as a string, as opposed to writing it to the scripts standard output

print_r($my_array);

// Output:
// Array ( [0] => elem_1 [1] => elem_2 [2] => elem_3 )

– Using var_dump() function:

Var_dump() is capable of outputting the value of more than one variable at the same time. Var_dump() outputs the data types of each value.

var_dump($my_array);

// Output:
// array(3) { [0]=> string(6) "elem_1" [1]=> string(6) "elem_2" [2]=> string(6) "elem_3" }
