 String Functions in PHP

PHP provides a wide range of built-in functions to manipulate strings. These functions can be used to perform tasks such as concatenation, trimming, searching, and replacing.

Example:

perl

$name = "John Doe";

$length = strlen($name); // string length

$upper = strtoupper($name); // convert to uppercase

$lower = strtolower($name); // convert to lowercase

$replace = str_replace("John", "Mary", $name); // replace string
