Just to add to what dan at cain dot sh mentioned, is_array() returns false if the argument is an
object, even though objects can be treated as arrays:
Example:
<?php
$arr = array(1, 2, 3);
print_r($arr);
print((is_array($arr) ? "Is Array" : "Not array") . "\n\n");
class MyObj {
var $pMyVar = 4;
}
$arr = new MyObj;
print_r($arr);
print((is_array($arr) ? "Is Array" : "Not array") . "\n\n");
?>
Output:
Array
(
[0] => 1
[1] => 2
[2] => 3
)
Is Array
myobj Object
(
[pMyVar] => 4
)
Not array
