In PHP, how do I compare strings with examples?

In PHP, you can compare strings using various methods. The most common ways to compare strings are:

  • == (Equality operator)
  • === (Identity operator)
  • != (Not equal operator)
  • !== (Not identical operator)
  • strcmp() (String comparison function)

Here's an example of how to compare strings in PHP:

<?php $str1 = "Hello World"; $str2 = "Hello World"; $str3 = "Hello PHP"; // Using == operator if ($str1 == $str2) { echo "Strings are equal using == operator.<br>"; } // Using === operator if ($str1 === $str2) { echo "Strings are identical using === operator.<br>"; } // Using != operator if ($str1 != $str3) { echo "Strings are not equal using != operator.<br>"; } // Using strcmp function if (strcmp($str1, $str2) == 0) { echo "Strings are equal using strcmp().<br>"; } ?>
