How can I easily view all members of an array?


To view all the members of an array with minimal code, the simplest way is to use print_r - this will show you the members of an array like this:

<?php
$values 
= array("banana","apple","pear","banana");
print_r($values);
?>


Outputs:

Array
(
[0] => banana
[1] => apple
[2] => pear
[3] => banana
)

Less well known but useful when you require more detailed information on each array member is the function var_dump.

This will return the below for the array members above:

array(4) {
[0]=>
string(6) "banana"
[1]=>
string(5) "apple"
[2]=>
string(4) "pear"
[3]=>
string(6) "banana"
}
