Remove multiple whitespaces

🚀 How to Remove Multiple Whitespaces in PHP - A Simple Guide

Are you having a hard time removing multiple whitespaces from your PHP code? Don't worry, you're not alone! In this blog post, we'll address this common issue and provide you with easy solutions. So, let's dive in and clean up those pesky whitespaces!

🤔 The Problem

The user encountered a situation where they needed to remove all types of whitespace, including special characters like \n and \t, from a string retrieved from a MySQL database. However, their initial attempt using regular expressions didn't yield the desired results.

💡 The Solution

Fortunately, there are alternative methods to achieve the desired outcome. Let's explore a couple of simple solutions that will help you remove multiple whitespaces effectively.

Solution 1: Using the preg_replace Function

The preg_replace function can be used to perform pattern matching and replacement. To remove multiple whitespaces, including special characters, you can tweak the regular expression used by the function.

$row['message'] = "This is   a Text \n and so on \t     Text text.";
$row['message'] = preg_replace('/\s+/', ' ', $row['message']);
echo $row['message'];

By modifying the regular expression to /\s+/, we are now able to remove both single and multiple whitespaces, as well as special characters like \n and \t.

Solution 2: Using the trim and preg_replace Functions

In some cases, you might encounter leading or trailing whitespaces that need to be removed as well. In such scenarios, you can combine the trim and preg_replace functions to ensure all whitespaces are eliminated.

$row['message'] = " This is   a Text \n and so on \t     Text text. ";
$row['message'] = trim(preg_replace('/\s+/', ' ', $row['message']));
echo $row['message'];

Here, the trim function is used to remove any leading or trailing whitespaces before applying the preg_replace function. This combination guarantees that all instances of whitespaces, including special characters, are removed from the string.
