What are some alternative methods, besides regular expressions, for extracting specific data from a string in PHP?

When extracting specific data from a string in PHP, besides regular expressions, one alternative method is using the `explode()` function to split the string based on a delimiter. Another method is using the `substr()` function to extract a portion of the string based on the starting position and length. Additionally, the `strpos()` function can be used to find the position of a specific substring within the string.

// Using explode() to extract data from a string based on a delimiter
$string = "John,Doe,30";
$data = explode(",", $string);
echo $data[0]; // Output: John

// Using substr() to extract a portion of the string
$string = "Hello World";
$substring = substr($string, 6, 5);
echo $substring; // Output: World

// Using strpos() to find the position of a substring within the string
$string = "The quick brown fox jumps over the lazy dog";
$position = strpos($string, "fox");
echo $position; // Output: 16
