What are some alternative methods to extract substrings before and after a specific character in PHP?

When extracting substrings before and after a specific character in PHP, one alternative method is to use the `explode()` function to split the string into an array based on the specified character, and then access the desired substrings using array indexing. Another method is to use `strpos()` to find the position of the character, and then use `substr()` to extract the substrings before and after that position.

// Using explode() function
$string = "Hello, World!";
$delimiter = ",";
$parts = explode($delimiter, $string);
$before = $parts[0];
$after = $parts[1];

echo "Before: " . $before . "<br>";
echo "After: " . $after . "<br>";

// Using strpos() and substr() functions
$string = "Hello, World!";
$delimiter = ",";
$pos = strpos($string, $delimiter);
$before = substr($string, 0, $pos);
$after = substr($string, $pos + 1);

echo "Before: " . $before . "<br>";
echo "After: " . $after . "<br>";
