utf8 without BOM encoding in eclipse
After some headache I figured out that eclipse using set encoding UTF8 (with BOM) causes an error. It causes whitespace to be added when you use an include causing the headers of a webpage to render within the body in chrome.
ie. on index.php with no gap before or after the of course
<?php include_once('header.php'); ?><body>test</body>
and header.php having (without gaps again of course)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>test title</title>
</head>
Then the test title appears within the body (not in view source, but in the console in chrome). This causes a gap at the top of the page.
Opening the index.php and header.php in notepad++ and changing the encoding to UTF8 without BOM solves the problem. How can I fix this in Eclipse?! Switching to notepad++ is not desireable, too many good features in eclipse that are useful (better autocomplete, automatic versioning etc).
A mystery to me...
Answer
In eclipse, just change the encoding of the file to iso (Right click on file - > Properties) and delete the first three BOM characters, save file and reopen it.
