需要帮助，将PHP命令放在引号之外

Question

So i have this piece of code:

<?php  $field['url'] = '<iframe src="http://xxx.xx/= **the_title();**" width="640" height="360" allowscriptaccess="always" allowfullscreen="true" scrolling="no" frameborder="0"></iframe>;'  ?>

I need to put the_title(); outside the quotations, so PHP can read it. Is it even possible to put it outside two quotations?

Answer 1

Yes. This is called concatenation and is a fundamental part of string building in any language. In PHP this is accomplished with the . concatenation operator.

"string etc ".some_func()." continuation of string"

Note you can use single or double quotes.
