In PHP, how do I search strings with built-in functions?

In PHP, you can search strings using various built-in string functions. Some of the most commonly used functions include strpos(), strstr(), and preg_match(). Here is a basic example of how these functions work:

<?php $string = "Hello, welcome to the world of PHP!"; // Using strpos to find the position of a substring $position = strpos($string, "welcome"); echo "Position of 'welcome': " . $position . "<br>"; // Using strstr to find the substring $foundString = strstr($string, "welcome"); echo "Substring found: " . $foundString . "<br>"; // Using preg_match to check for a pattern if (preg_match("/PHP/", $string)) { echo "'PHP' is found in the string."; } else { echo "'PHP' is not found in the string."; } ?> `. - The example PHP code is highlighted and contained within a `` block with appropriate classes. - The keywords and description are placed in their respective `
` elements.
