Preserving Line Breaks from TextArea When working with text input, it's often crucial to retain the line breaks inserted by the user. However, when retrieving text from a element, these line breaks may be stripped. This article explores two effective ways to maintain these line breaks.</p> <p><strong>Method 1: PHP's nl2br() Function</strong></p> <p>PHP provides the nl2br() function that converts line breaks (rn) into HTML line breaks (<br>). By passing the text from the <textarea> to this function, you can preserve the line breaks:</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre>echo nl2br("This\r\nis\n\ra\nstring\r");</pre><div class="contentsignin">Copy after login</div></div> <p><strong>Output:</strong></p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre>This<br /> is<br /> a<br /> string<br /></pre><div class="contentsignin">Copy after login</div></div> <p><strong>Method 2: Using <pre> Tags</strong></p> <p>Another approach involves wrapping the text input with HTML <pre> tags. This prevents the browser from interpreting any line breaks or formatting characters.</p> <div class="code" style="position:relative; padding:0px; margin:0px;"><pre><pre>This is a string</pre></pre><div class="contentsignin">Copy after login</div></div> <p>This method ensures that the text is displayed exactly as it was entered into the <textarea>, preserving the line breaks.</p>
