Comparison operators
Comparison operators in PHP are used to compare two values and return a boolean result (true or false) based on the comparison. Here are the comparison operators supported in PHP:
Equal (==)
Checks if two values are equal.
$x == $y; // true if $x is equal to $y
Identical (===)
Checks if two values are equal and of the same data type.
$x === $y; // true if $x is equal to $y, and they are of the same data type
Not equal (!=) or Not identical (!==)
Checks if two values are not equal or not of the same data type, respectively.
$x != $y; // true if $x is not equal to $y
$x !== $y; // true if $x is not equal to $y, or they are not of the same data type
Greater than (>)
Checks if the left operand is greater than the right operand.
$x > $y; // true if $x is greater than $y
Less than (<)
Checks if the left operand is less than the right operand.
$x < $y; // true if $x is less than $y
