How does the trim() function work in PHP?

The trim() function in PHP is used to remove whitespace or other specified characters from the beginning and end of a string. This can be helpful when working with user input or data that may have extra spaces. To use the trim() function, simply pass the string you want to trim as an argument, and it will return a new string with the specified characters removed. 

$string = "   Hello, World!   ";
$trimmedString = trim($string);
echo $trimmedString; // Output: "Hello, World!"
