Invisible line breaks in html via variables (PHP)

PHP
1

Consider the following code:

$Img1 = '<div><img src="images.png"></div>';
$Img2 = '<div><img src="images2.png"></div>';

This is what my HTML looks like when I echo $Img1 and $Img2 together:

<div><img src="images.png"></div><div><img src="images2.png"></div>

This is what I would like it to look like:

<div><img src="images.png"></div>
</div><div><img src="images2.png"></div>

In other words, I would like to have nicely formatted HTML, preferably without inserting breaks…

<br/>

Is there a way to modify $Img1 and #Img2 to accomplish this? I’ve tried /n, /r/n, etc., but I’m either doing something wrong or they only work when echoing the values.

Thanks.

\n, \r\n, and \r all have to be within double quotes, not single quotes.

Were the control characters enclosed with double or single quotes?

Also forgot to mention that it’s written with a backslash (\) and not a forward slash (/). The order in which they face matters. :slight_smile:

I’m back on the desktop…

Try the following script Using PHP HereDoc Strings:


// BEWARE: ONLY LINEFEED AFTER ____EOT
$imgs = <<< ____EOT
  <div class="w88 mga bgr tac">
    <img 
      src="https://via.placeholder.com/110" 
      width="180" 
      alt="#" 
    />

    <img 
      src="https://via.placeholder.com/220" 
      width="180" 
      alt="#" 
    />

    <img 
      src="https://via.placeholder.com/320" 
      width="180" 
      alt="#" 
    />

    <img 
      src="https://via.placeholder.com/420" 
      width="180" 
      alt="#" 
    />

  </div>
____EOT;
// BEWARE: ONLY LINEFEED AFTER ;

# Maybe CRUNCH  
  if(true):
    $imgs = str_replace(["\n", "\r", "\t", "  "], '', $imgs);
  endif;  

echo $imgs;

I mean, at that point, I’d just go with Twig:

{% spaceless %}
<div class="w88 mga bgr tac">
    <img 
      src="https://via.placeholder.com/110" 
      width="180" 
      alt="#" 
    />

    <img 
      src="https://via.placeholder.com/220" 
      width="180" 
      alt="#" 
    />

    <img 
      src="https://via.placeholder.com/320" 
      width="180" 
      alt="#" 
    />

    <img 
      src="https://via.placeholder.com/420" 
      width="180" 
      alt="#" 
    />

</div>
{% endspaceless %}

The <br> tag will not put line breaks in your html code, it only puts line breaks in the displayed output in the browser.

Backslash n will do it in doulbe quotes.

$Img1 = "<div><img src="images.png"></div>\n";
$Img2 = "<div><img src="images2.png"></div>\n";

Thanks for all the tips. I don’t know how I got the backslash turned around. I knew there was a difference, and I thought I was doing it right. :wink:

I’ll give the HereDoc string a try, too.
