PHP Programming/Comparison

The operators for comparison in PHP are the following:

Operator	Name	Returns `true`, if…
`==`	equal	left & right side equals
`===`	identical	`==` is `true`, and both sides have the same type
`!=`	not equal	left & right are not equal after type juggling
`<>`	not equal	synonym of `!=`
`!==`	not identical	`!=` is `true`, or their types differ
`<>`	not equal	synonym of `!=`
`<`	less than	left side is strictly less than right side
`>`	greater than	left side is strictly greater than right side
`<=`	less than or equal to	left side is less than or equal to right side
`>=`	greater than or equal to	left side is greater than or equal to right side
`<=>`	spaceship	integer less than, equal to, or greater than zero when left side is respectively less than, equal to, or greater than right side (≥ PHP 7).
`$a` `??` `$b` `??` `$c`	null coalescing	first operand from left to right that exists and is not `NULL`. `NULL`, if no values are defined and that not `NULL` (≥ PHP 7).

Example of comparisons

This example sets and prints arrays.

PHP Code:

<?php
$value1 = 5;
$value2 = 7;

if ($value1 == $value2) {
 print('value1 is equal to value2');
} else {
 print('value1 is unequal to value2');
}
?>

PHP Output:

value1 is unequal to value2

HTML Render:

value1 is unequal to value2
