The `ltrim()` function in PHP is used to remove whitespace or other predefined characters from the beginning (left side) of a string. This function is available in both PHP 8.1 and PHP 8.2. Here’s how you can use it with an example:
<?php // Original string with leading whitespace $string = " Hello, World!"; // Trim whitespace from the beginning of the string $trimmed_string = ltrim($string); // Output the trimmed string echo "Original string: '$string'<br>"; echo "Trimmed string: '$trimmed_string'"; ?>
In this example, the `ltrim()` function is applied to the original string `” Hello, World!”`. It removes the leading whitespace characters from the beginning of the string. The resulting trimmed string is then stored in the variable `$trimmed_string`.
The output will be:
Original string: ' Hello, World!' Trimmed string: 'Hello, World!'
This function is useful when you need to sanitize user input or clean up strings where leading whitespace might be present.
