How to determine if an array has any elements or not?

You can use the count() or sizeof() PHP functions:

if (sizeof($result) > 0) {    echo "array size is greater than zero";}else {    echo "array size is zero";}

Or you can use:

if (count($result) > 0) {    echo "array size is greater than zero";}else {    echo "array size is zero";}

count — Count all elements in an array, or something in an object

int count ( mixed $array_or_countable [, int $mode = COUNT_NORMAL ] )

Counts all elements in an array, or something in an object.

Example:

<?php    $a[0] = 1;    $a[1] = 3;    $a[2] = 5;    $result = count($a);    // $result == 3

In your case, it is like:

if (count($array) > 0){    // Execute some block of code here}

You could avoid length retrieve and check using a simple foreach:

foreach($result as $key=>$value) {    echo $value;}
