How to check if Two Strings are Equal in PHP - Step by Step Examples
How to check if Two Strings are Equal in PHP ?
Answer
In PHP, you can use the ==
operator or the strcmp()
function to check if two strings are equal.
✐ Examples
1 Check Equality using == Operator
In this example,
- We create two string variables
$str1
and$str2
with the same value"Hello"
. - We check if
$str1 == $str2
, which will returntrue
if they are equal, even if they are of different types, andfalse
otherwise. - Finally, we echo the result.
PHP Program
<?php
$str1 = "Hello";
$str2 = "Hello";
$result = ($str1 == $str2);
echo "Are strings equal? ".var_export($result, true);
?>
Output
Are strings equal? true
2 Check Equality using strcmp() Function
In this example,
- We create two string variables
$str1
and$str2
with the same value"Hello"
. - We use the
strcmp()
function to compare$str1
and$str2
, which will return0
if they are equal, a negative value if$str1
is less than$str2
, and a positive value if$str1
is greater than$str2
. - Finally, we echo the result.
PHP Program
<?php
$str1 = "Hello";
$str2 = "Hello";
$result = strcmp($str1, $str2);
echo "Are strings equal? ".($result == 0 ? 'true' : 'false');
?>
Output
Are strings equal? true
