Compare Two Strings using a Hashing Function
For a more advanced approach, you could use a hashing function to compare the strings.
PHP
<?php function compareStrings($str1, $str2) { return hash('sha256', $str1) === hash('sha256', $str2); } // Driver code $str1 = "Geeks"; $str2 = "Geeks"; if (compareStrings($str1, $str2)) { echo "The strings are equal."; } else { echo "The strings are not equal."; } ?> |
Output
The strings are equal.
Explanation:
- The
compareStringsfunction uses thehashfunction to generate a SHA-256 hash of each string. - It then compares the hashes. If the hashes are equal, the strings are considered equal.
How to Compare Two Strings without using strcmp() function in PHP ?
