Hello Friends Today, through this tutorial, I will tell you How do you trim whitespace from the beginning and end of a string using PHP, PHP 8, PHP 8.1, PHP 8.2, PHP 8.3 With Example. In PHP, you can trim whitespace (including spaces, tabs, and newlines) from the beginning and end of a string using the `trim()` function. Here’s how you can use it:
<?php // 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 trimmed string echo "Original string: '$string'<br>"; echo "Trimmed string: '$trimmed_string'"; ?>
In this example, the `trim()` function removes any whitespace characters from the beginning and end of the original string. The trimmed string is then stored in the variable `$trimmed_string`.
After trimming, the output will be:
Original string: ' Hello, World! ' Trimmed string: 'Hello, World!'
This function is particularly useful when you need to sanitize user input or clean up strings obtained from external sources where leading and trailing whitespace might be present.
