In PHP, how do I compare strings in vanilla PHP?

In vanilla PHP, you can compare strings using various operators such as `==`, `===`, `!=`, `!==`, `<`, `>`, `<=`, and `>=`. The double equals `==` operator checks for value equality, while the triple equals `===` operator checks for both value and type equality.

Here’s an example of how to compare strings:

<?php $string1 = "Hello World"; $string2 = "Hello World"; $string3 = "hello world"; // Check for value equality if ($string1 == $string2) { echo "String1 is equal to String2"; // This will be printed } // Check for value and type equality if ($string1 === $string2) { echo "String1 is identical to String2"; // This will be printed } // Case-sensitive comparison if ($string1 == $string3) { echo "String1 is equal to String3"; // This will NOT be printed } else { echo "String1 is NOT equal to String3"; // This will be printed } ?>
