What does the star * in php mean?

[pneudralics]

I hired a coder to build me a small section for a website. I've never seen the * used before and was just wondering what it meant.

 

print $user."*".$id;

That's just a string, it's not doing anything. All that line of code does is print out of the variable $user then * then the variable $id

 

Ex:

 

$user = 'foo';
$id = 1;
print $user."*".$id; // Output: foo*1

Did you even try running the code to see what happens?

It is more commonly used as a mathematical operator for multiplication.

 

<?php
echo 8*8; //equivalent to 8x8 or 8 multiplied by 8.  Notice it is not being used in string format as in the original example.
?>
