Are there any specific PHP functions or methods recommended for handling text string manipulation tasks?

When handling text string manipulation tasks in PHP, there are several built-in functions that are recommended for efficient and effective processing. Some commonly used functions include `strlen()` for getting the length of a string, `substr()` for extracting a portion of a string, `str_replace()` for replacing occurrences of a substring, `strtolower()` and `strtoupper()` for converting a string to lowercase and uppercase respectively, and `trim()` for removing whitespace from the beginning and end of a string. 

// Example code snippet demonstrating the use of some recommended PHP string manipulation functions
$string = "Hello, World!";
$length = strlen($string);
$substring = substr($string, 0, 5);
$replacedString = str_replace("Hello", "Hi", $string);
$lowercaseString = strtolower($string);
$uppercaseString = strtoupper($string);
$trimmedString = trim($string);

echo "Length of string: " . $length . "\n";
echo "Substring: " . $substring . "\n";
echo "Replaced string: " . $replacedString . "\n";
echo "Lowercase string: " . $lowercaseString . "\n";
echo "Uppercase string: " . $uppercaseString . "\n";
echo "Trimmed string: " . $trimmedString . "\n";
