Can the relational operator === (used for identical) be used interchangeably with the != operator" and get the same results? Or will I eventually run into issues later down the road when I do larger programs?
I know I will get the same results in the example below, will this always be true?
//example 1
<?php
$a = 1; //integer
$b = '1'; //string
if ($a === $b) {
echo 'Values and types are same';
}
else {
echo 'Values and types are not same';
}
?>
// example 2
<?php
$a = 1; //integer
$b = '1'; //string
if ($a != $b) {
echo 'Values and types are not same';
}
else {
echo 'Values and types are same';
}
?>
