A quick question about PHP

In a text of code like this, the " marks and the ' confuse me a little. To be certain let me see if I got this right.

The first ' is paired with the last ' while the two in the middle are paired together? Or is it opposite? If not, how can the browser distinguish the difference? Because they're inside the " marks does it allow the browser to comprehend?

 echo '<a href="shirt.php?id=' . $product_id . '">';

Any help on this is much appreciated.

I believe the first two will pair together, turning this block of code into a string

'<a href="shirt.php?id='

Then you concatenate the variable, and to that variable you concatenate the next part of your code between single '


So it's not like html where the tags are nested. The first is closed with the second, the third is closed by the fourth. The " inbetween is treated like a part of the string I suppose, and not considered an opening mark by php.

ah, okay I see. I guess that would explain the need for the periods for $product_id.
