What are some best practices for handling and manipulating strings in PHP to extract specific information?

When handling and manipulating strings in PHP to extract specific information, it is important to use built-in string functions such as strpos(), substr(), and explode(). These functions allow you to search for specific substrings, extract portions of a string based on character positions, and split a string into an array based on a delimiter. By utilizing these functions effectively, you can easily extract the desired information from a string.

// Example: Extracting a specific substring from a longer string
$string = "Hello, World!";
$substring = substr($string, 7, 5); // Extract "World" starting from position 7 with a length of 5
echo $substring; // Output: World
