Summary<\/strong>: in this tutorial, you will learn how to use PHP comparison operators to compare two values.<\/p>\n\n\n\n

Introduction to PHP comparison operators #<\/a><\/h2>\n\n\n\n

A comparison operator allows you to compare two values and returns true<\/code> if the comparison is truthful and false<\/code> otherwise.<\/p>\n\n\n\n

The following table shows the comparison operators in PHP:<\/p>\n\n\n\n

Operator<\/th>Name<\/th>Description<\/th><\/tr><\/thead>
==<\/td>Equal to<\/td>Return true<\/code> if both operands are equal; otherwise, it returns false<\/code>.<\/td><\/tr>
!=, <><\/td>Not equal to<\/td>Return true<\/code> if both operands are equal; otherwise, it returns false<\/code>.<\/td><\/tr>
===<\/td>Identical to<\/td>Return true<\/code> if both operands have the same data type and are equal; otherwise, it returns false<\/code>.<\/td><\/tr>
!==<\/td>Not identical to<\/td>Return true<\/code> if both operands are not equal or do not have the same data type; otherwise, it returns false<\/code>.<\/td><\/tr>
><\/td>Greater than<\/td>Return true<\/code> if the operand on the left  is greater than the operand on the right; otherwise, it returns false<\/code>.<\/td><\/tr>
>=<\/td>Greater than or equal to<\/td>Return true<\/code> if the operand on the left  is greater than or equal to the operand on the right; otherwise, it returns false<\/code>.<\/td><\/tr>
<<\/td>Less than<\/td>Return true<\/code> if the operand on the left is less than the operand on the right; otherwise, it returns false<\/code>.<\/td><\/tr>
<=<\/td>Less than or equal to<\/td>Return true<\/code> if the operand on the left  is less than or equal to the operand on the right; otherwise, it returns false<\/code>.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Equal To Operator (==) #<\/a><\/h3>\n\n\n\n

The equal to operator returns true<\/code> if both values are equal; otherwise, it returns false<\/code>. <\/p>\n\n\n\n

The following example returns true<\/code> because 10 is equal to 10:<\/p>\n\n\n

<?php<\/span>\n\n$x = 10<\/span>;\n$y = 10<\/span>;\n\nvar_dump($x == $y); \/\/ bool(true)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
The following example returns false<\/code> because 10<\/code> is not equal 20<\/code>:<\/p>\n\n\n
\n<?php<\/span>\n\n$x = 20<\/span>;\n$y = 10<\/span>;\nvar_dump($x == $y); \/\/ bool(false)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
The following example compares the number 20<\/code> with a string '20'<\/code>, it also returns true<\/code>.<\/p>\n\n\n
<?php<\/span>\n\n$x = '20'<\/span>;\n$y = 20<\/span>;\nvar_dump($x == $y); \/\/ bool(true)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
If you want to compare two values with the consideration of type, you can use the identical operator (===<\/code>).<\/p>\n\n\n\n
Not equal to operator (!=, <>) #<\/a><\/h3>\n\n\n\n
The not equal to (!=<\/code>, <><\/code>) operator returns true<\/code> if the lefthand value is not equal to the righthand value; otherwise, it returns false<\/code>. For example:<\/p>\n\n\n
<?php<\/span>\n\n$x = 20<\/span>;\n$y = 10<\/span>;\n\nvar_dump($x != $y); \/\/ bool(true)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Output:<\/p>\n\n\n
bool(true<\/span>)<\/code><\/span>Code language:<\/span> JavaScript<\/span> (<\/span>javascript<\/span>)<\/span><\/small><\/pre>\n\n\n
Identical operator (===) #<\/a><\/h3>\n\n\n\n
The identical operator returns true<\/code> if both values are equal and have the same type; otherwise returns false<\/code>.<\/p>\n\n\n\n
The following example uses the identical operator to compare a string and a number. It returns false<\/code> because these values have different types:<\/p>\n\n\n
<?php<\/span>\n\n$x = '20'<\/span>;\n$y = 20<\/span>;\nvar_dump($x === $y); \/\/ bool(false)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Not identical operator (!==) #<\/a><\/h3>\n\n\n\n
The not identical operator (!==) returns true<\/code> if the values are not equal or they do not have the same type; otherwise, it returns false<\/code>. For example:<\/p>\n\n\n
<?php<\/span>\n\n$x = 20<\/span>;\n$y = 10<\/span>;\n\nvar_dump($x != $y); \/\/ bool(true)<\/span>\n\n$x = 20<\/span>;\n$y = '20'<\/span>;\nvar_dump($x != $y); \/\/ bool(false)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Greater than (>) #<\/a><\/h3>\n\n\n\n
The greater-than operator returns true<\/code> if the lefthand value is greater than the righthand value; otherwise, it returns false<\/code>:<\/p>\n\n\n
<?php<\/span>\n\n$x = 10<\/span>;\n$y = 20<\/span>;\n\nvar_dump($x > $y); \/\/ bool(false)<\/span>\nvar_dump($y > $x); \/\/ bool(true)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Greater than or equal to (>=) #<\/a><\/h3>\n\n\n\n
The greater than or equal to operator returns true if the lefthand value is greater than or equal to the righthand value; otherwise, it returns false. For example:<\/p>\n\n\n
<?php<\/span>\n\n$x = 20<\/span>;\n$y = 20<\/span>;\n\nvar_dump($x >= $y); \/\/ bool(true)<\/span>\nvar_dump($y >= $x); \/\/ bool(true)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Less than (<) #<\/a><\/h3>\n\n\n\n
The less-than operator returns true if the lefthand value is less than the righthand value; otherwise, it returns false. For example:<\/p>\n\n\n
<?php<\/span>\n\n$x = 20<\/span>;\n$y = 10<\/span>;\n\nvar_dump($x < $y); \/\/ bool(false)<\/span>\nvar_dump($y < $x); \/\/ bool(true)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
Less than or equal to (<=) #<\/a><\/h3>\n\n\n\n
If the lefthand value is less than or equal to the righthand value, the less than or equal to operator returns true; otherwise, it returns false. For example:<\/p>\n\n\n
<?php<\/span>\n\n$x = 20<\/span>;\n$y = 20<\/span>;\n\nvar_dump($x <= $y); \/\/ bool(true)<\/span>\nvar_dump($y <= $x); \/\/ bool(true)<\/span><\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
