Sometime, we took a textarea and use enter information with new lines and all. Then after when he wants to show entered details then we have to show them exactly what he enter like with enter and space all. So textarea by default adding "\n" to content so you have to convert "\n" to newline. so here we will use nl2br() function and str_replace() function to replace \n to br.

So, let's see both example one by one.

Example 1: PHP Replace n with br using nl2br()

index.php

  1. <span class="pun">&lt;?</span><span class="pln">php</span>
  2. <span class="pln">$desc </span><span class="pun">=</span><span class="pln"> </span><span class="str">"Line one \n Line two \n Line three \n Live four \n Line five "</span><span class="pun">;</span>
  3. <span class="pln">echo nl2br</span><span class="pun">(</span><span class="pln">$desc</span><span class="pun">);</span>
  4. <span class="pun">?&gt;</span>

Output

  1. <span class="typ">Line</span><span class="pln"> one</span>
  2. <span class="typ">Line</span><span class="pln"> two</span>
  3. <span class="typ">Line</span><span class="pln"> three</span>
  4. <span class="typ">Live</span><span class="pln"> four</span>
  5. <span class="typ">Line</span><span class="pln"> five</span>
Example 2: PHP Replace n with br using str_replace()

index.php

  1. <span class="pun">&lt;?</span><span class="pln">php</span>
  2. <span class="pln">$desc </span><span class="pun">=</span><span class="pln"> </span><span class="str">"Line one \n Line two \n Line three \n Live four \n Line five "</span><span class="pun">;</span>
  3. <span class="pln">echo str_replace</span><span class="pun">(</span><span class="str">"\n"</span><span class="pun">,</span><span class="pln"> </span><span class="str">"&lt;br /&gt;"</span><span class="pun">,</span><span class="pln"> $desc</span><span class="pun">);</span>
  4. <span class="pun">?&gt;</span>

Output

  1. <span class="typ">Line</span><span class="pln"> one</span>
  2. <span class="typ">Line</span><span class="pln"> two</span>
  3. <span class="typ">Line</span><span class="pln"> three</span>
  4. <span class="typ">Live</span><span class="pln"> four</span>
  5. <span class="typ">Line</span><span class="pln"> five</span>
