哪种方法更有效，在单引号内使用双引号或转义单引号？ [关闭]

Question

I'm learning some php right now and I'm trying to identify a best practice for using quote marks. I've decided I'll be using single quotes and concatenate variables into strings when needed.

I've now come to adding CSS class/ids into my php. When adding a class or id tag in php it works with escaping single quotes inside my single quotes OR using non-escaped paired double quotes inside the single quotes. So which is more efficient?

Example:

echo '<span class=\'big\'>This is big text</span>';

or

echo '<span class="big">This is big text</span>';

I am not going to say witch one is best, this is a personal choice but I would say that W3C uses for the HTML code " so your code needs to look like this:

<span class="class_name">Text here</span>

(I would go with single quote, this way you can write clean HTML code that will render as it should with "" browser)

Hope that helps.
