Keep white space with htmlentities

Question

Currently, this is my code

$str = file_get_contents($sFile);
echo nl2br(htmlentities($str));

How can I keep the whitespace (tab and multiple spaces) in the files when i output them?

Example Input:

if(a==b){
  code   
    more code 
}

Should ouput exactly that (with htmlentities applied), but currently outputs

if(a==b){
code
more code
}

How can I keep whitespace?

The browser will automatically collapse/convert the whitespace characters into a single space. You can wrap the text in a
element — , May 02 '16 at 04:09

Wrap the output in <pre>...</pre> tags:

<pre>
if(a==b){
  code   
    more code 
}
</pre>

Browsers ignore superfluous whitespace, so you have to tell it not to ignore it.

You can use html entity for space to keep the space:

echo str_replace([' ', "\t"], [' ', '  '], nl2br(htmlentities($str)));
