Testing if a variable is an array is easy. Just use the is_array() function. Here is a PHP script on how to use is_array():
<?php
$var = array(0,0,7);
print("Test 1: ". is_array($var)."\n");
$var = array();
print("Test 2: ". is_array($var)."\n");
$var = 1800;
print("Test 3: ". is_array($var)."\n");
$var = true;
print("Test 4: ". is_array($var)."\n");
$var = null;
print("Test 5: ". is_array($var)."\n");
$var = "PHP";
print("Test 6: ". is_array($var)."\n");
print("\n");
?>
This script will print:
Test 1: 1 Test 2: 1 Test 3: Test 4: Test 5: Test 6:
