[Resolved] [Resolved] php echo 'html' vs \"html\"

[azunoman]

My ? is....why, when echoing html code via PHP, do people tend to use the html (\"). I understand why the escape character is used but if one just changes the html code to be echoed by using a single quote (') instead of ("), the escape character is not needed.

I have used the (') in place of the (") extensivley in my form processing, about 17 forms, and all works well. What if any problems will I run into?

The following depicts what I am trying to convey. The first if uses the single ' and no escape character. The 2nd if is how I typically see an html element echoed.

    

<li<?php if ($thisPage=="Page One")         

echo " id='currentpage'"; ?>>        <a href="#">Page One</a></li>      

<li<?php if ($thisPage=="Page Two")         

echo " id=\"currentpage\""; ?>>        <a href="#">Page Two</a></li>

Double quotes can be a preference. They also allow parsing between them, while single quotes don't.

$var = "blah";
echo "$var"; //outputs blah
echo '$var'; //outputs $var

I also believe (if memory serves correct), that double quotes are the standard for xhtml

LordShryku, yea..the ? pertained to html, not variables. But thanks for the input.

cmose, your memory serves you very well...

xhtml....Attribute values must always be quoted

quoted doesnt just mean double quotes. single is fine in XML, and therefore is in XHTML.

moonglobe...I have my fingers crossed that you are correct about the quote thing. But why would they state that all attribute values be quoted, as in the "attribute" is quoted with the quotation mark.

New Flash!...I checked the html of my code via w3.org validatior and it passed.

why? maybe they assumed the people readin the spec wouldnt be closed-minded?:rolleyes:

no seriously though, i dont know, but i'm sure that single quotes are fine.
