How can special characters be used as delimiters for string manipulation in PHP?

Special characters can be used as delimiters for string manipulation in PHP by using functions like explode() and implode(). The explode() function splits a string into an array based on a specified delimiter, while implode() joins array elements into a string using a specified delimiter. This can be useful for parsing and manipulating strings that have specific patterns or structures.

// Example of using special characters as delimiters for string manipulation
$string = "apple,banana,cherry";
$delimiter = ",";
$array = explode($delimiter, $string);

// Output the array elements
foreach ($array as $value) {
    echo $value . "<br>";
}
