PHP Whitespace Removal for RSS

[username]

Hi,

I am pulling some text from a MySQL DB field, and displaying in an RSS Feed. Single paragraph content works fine, but multi paragraph variables are causing the error "Whitespace is not allowed at this location" in the RSS file. How do I remove the whitespace from the string?

Example:

$var = "one two

three";

I have tried regular expressions and str_replace. No luck so far.

Thanks in advance.

what did you try str_replace on? did you try it on a \n?

[rocknbil]

$var = preg_replace('/[\n\r]+/',' ',$var);

Hmm, strangely enough, it produces the same error in a different place in the document with rocknbil's code added. Any ideas?

[username]

So, any ideas?

[TheMadScientist]

$var = preg_replace('/[\n\r\t]+/',' ',$var);

Is about the only guess I have...

[andrewsmd]

I've always had strange results with the regex replace functions try using three str replace functions one for each. I know it's more code, but I tend to get more reliable results with them.

To expand on andrewsmd's idea, you can actually feed arrays into str_replace:

$WhiteSpace = array("\r\n", "\n", "\r", "\t");
$ReplaceWith = " ";
$NewStr = str_replace($WhiteSpace, $ReplaceWith, $String);
