Hello Friends Today, through this tutorial, I will tell you How to Use `trim()` function using PHP, PHP 8, PHP 8.1, PHP 8.2 With Example. In PHP 8.1 and PHP 8.2, the `trim()` function is used to remove whitespace or other predefined characters from the beginning and end of a string. Here’s how you can use it with an example:

// Example usage of trim() function in PHP 8.1 and PHP 8.2

// Original string with leading and trailing whitespace
$string = " Hello, World! ";

// Trim whitespace from the beginning and end of the string
$trimmed_string = trim($string);

// Output the original and trimmed string
echo "Original string: '$string'<br>";
echo "Trimmed string: '$trimmed_string'";


In this example:

1. The original string `$string` contains leading and trailing whitespace.
2. The `trim()` function is used to remove the whitespace from the beginning and end of the string.
3. The resulting trimmed string is stored in the variable `$trimmed_string`.
4. Finally, both the original and trimmed strings are echoed out.

The output will be:

Original string: ' Hello, World! '
Trimmed string: 'Hello, World!'

This function is commonly used for cleaning up user input or sanitizing strings obtained from external sources where leading and trailing whitespace might be present.
