Wrapping '%' In Quotes?

[boxturt]

That's not a good topic title, I apologize.

 

I've always thought that when defining width or height or anything else that anything BUT an absolute number should be wrapped in double quotes.

Like width=950 OR width="!00%" . I need to define "100%", "top", "center", etc but of course php says "no, No, NO!"

So I have tried:

><?
echo "<table width=100% align=center border=0 cellpadding=5 cellspacing=1>\n<tr valign=top align=center>\n";
?>

 

That works but is it correct? I wonder if that should all be in 'single' quotes (also works)

 

><?
echo "<table width='100%' align='center' border=0 cellpadding=5 cellspacing=1>\n<tr valign='top' align='center'>\n";
?>

 

Thanks,

 

Happy New Year!

This should work:

 

><?php
echo '<table width="100%" align="center" border="0" cellpadding="5" cellspacing="1">' . "\n" . '<tr valign="top" align="center">' . "\n";
?>

You're welcome. I'm glad that I could help.

Or of course just escape the quotes like \"

 

><?
echo "<table width=\"100%\" align=\"center\" border=\"0\" cellpadding=\"5\" cellspacing=\"1\">\n<tr valign=\"top\" align=\"center\">\n";
?>

 

But my personal preference is to always use single quotes when possible for PHP strings since it gives a slight speed boost compared to double quotes. This is because PHP scans double quotes strings for variables and special characters (like \n) but with single quotes it only looks for \'. Whilst the speed difference with a single string is negligible imagine outputting a whole scripts worth. This is why Bob's method is preferable.

 

Oh and always wrap your html attributes in double quotes. That is the standard.
