Interesting behavior comparing integer with array in PHP

问题

In PHP I had to compare if an integer variable was less than a value of an array, but I had an error in the code and I found by chance an unexpected behavior.

I was comparing the integer with the array itself and it was returning true. Do you know why?

I've been searching about this in StackOverflow and php.net (PHP types comparisons) and I didn't found a specific answer.

Here you have a little code to test this.

<?php

$myArray = array();
$myInt = 1;

if($myInt < $myArray){
    echo "Int less than array\n";
}

if($myInt == $myArray){
    echo "Int equal to array\n";
}

if($myInt > $myArray){
    echo "Int greater than array\n";
}

I've tried different values for $myInt and different contents for $myArray and it always prints this:

Int less than array

Comparing an array to anything else result in array is always greater :
