PHP Comparison Operators
PHP Comparison operators are used to compare the values of two elements and return a boolean result. Comparison operators supported by PHP are ==,!=,<,>,<=,>=.
| Operator | Name | example | Description |
|---|---|---|---|
| == | Equal to | $m == $n | It will return true if both operands[$m and $n] are equal. |
| !=, <> | Not equal to | $m != $n | It will return true if both operands[$m and $n] are not equal. |
| === | Identical to | $m === $n | It will return true if both operands[$m and $n] are equal and exact same type. |
| !== | Not identical to | $m !== $n | It will return true if both operands[$m and $n] are not equal or exact same type. |
| > | Greater than | $m < $n | It will return true if $m is less than $n. |
| >= | Greater than or equal to | $m > $n | It will return true if $m is greater than $n. |
| < | Less than | $m <= $n | IIt will return true if $m is less than or equal to $n |
| <= | Less than or equal to | $m >= $n | It will return true if $m is greater than or equal to $n |
Equality Operator (==)
It will return true if both operands are equal. else it will return false. in the following example, $m is equal to $n.Hence TRUE is returned.
<?php
$m = 200;
$n = "200";
var_dump($m == $n); // it will return true because values are equal
?>
Output:
