Removing Line Breaks and Newlines in PHP

CKEditor is adding new lines in my content that's entered into my database, which is fine, except that this data needs to be rendered to javascript as a single line of html.

In my PHP I have:

$tmpmaptext = $map['maptext'][$this->config->get('config_language_id')];
$tmpmaptext = html_entity_decode($tmpmaptext, ENT_QUOTES, 'UTF-8');
$tmpmaptext = str_replace(array('\r\n', '\n', '\r', '\t'), '', $tmpmaptext);
$tmpmaptext = str_replace(PHP_EOL, '', $tmpmaptext);

Which is pretty much everything I can find on how to remove new lines but I'm still ending up with this in the page:

var infowindow01 = new google.maps.InfoWindow({  
        content:  '<div><h2>Title</h2>

<p>Address line 1,<br />
Address line 2</p>

<p>phone number</p>

<p><a href="http://www.example.com" target="_blank">www.example.com</a></p>
</div>'

How can I get all these new lines out without removing that normal spacing between characters?

This did the trick:

$tmpmaptext = $map['maptext'][$this->config->get('config_language_id')];
$tmpmaptext = preg_replace('/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/', '', $tmpmaptext);

Was able to remove all the rest and it renders perfectly now.

I think it's because you're using single-quotes in str_replace which will search for the string '\n' (slash n). If you use double-quotes it will convert \n to the newline character...

$maptext = '<div><h2>Title</h2>

<p>Address line 1,<br />
Address line 2</p>

<p>phone number</p>

<p><a href="http://www.example.com" target="_blank">www.example.com</a></p>
</div>';

$no_newlines = str_replace(array("\n", "\r\n", "\r", "\t", "    "), "", $maptext);

echo($no_newlines);

outputs: 

<div><h2>Title</h2><p>Address line 1,<br />Address line 2</p><p>phone number</p><p><a href="http://www.example.com" target="_blank">www.example.com</a></p></div>
