How to print the contents of an array using PHP

Written by Ian Carnaghan · 19 sec read >

//Array example
$arr = array(‘one’,’two’,’three’,’four’);

Use the print_r function.

Example: print_r($arr);

The example above will print out the following:
Array ( [0] => one [1] => two [2] => three [3] => four )

NOTE: If you want to have the contents of the array displayed in a more readable format, add a echo ‘<pre>’; statement before calling the print_r function.

Example of the results:

    [0] => one
    [1] => two
    [2] => three
    [3] => four


print_r – Prints human-readable information about a variable (PHP 4, PHP 5)
