print_r VS echo

[EY]

Why use print_r  instead of echo?

Are they the same thing? If not what is the difference?

 

Thanks in advance.

They are not the same, print_r is to display the contents of an array or object. read the manual on what each do.

The only time I ever use print_r is when I want to display all elements of an array, mainly in development and debugging.

[MadTechie]

print_r — Prints human-readable information about a variable

echo — Output one or more strings

 

try this

<?php
$myArray = array("test", "123");
echo "echo=".$myArray;
echo "print_r=";
print_r($myArray);

?>
