Removing whitespace from code

[etrader]

In my php and html code I have lots of whitespace and line breaks between the <tags>. How I can remove all useless whitespace and linebreaks without altering the main text and codes?

Get an IDE that has auto-formatting.

how to use this code? I have a set of php processes ending to a series of echo for strings.

 

I put this code at the beginning and at the end of the whole code, but no effect

Sorry, are you referring to the actual code, or the result of your code?

Image some string which get content from an external webpage and displaying them with echo. Now, there are lots of useless whitespace between the codes.

 

e.g.

$string1=file_get_content(http://external.com);
$string2 ='<some code>



</div>'
echo $string1;
echo $string2;
