Question about syntax

[wohlm]

I'm going through this book and I've came across this operator

 

'|'  What purpose does it serve?

 

This is the example I was given

 

echo '|'.$products[0][0].'|'.$products[0][1].'|'.$products[0][2].'|<br />';

 

It's printing the products array by key and value, but I don't know what that operator is.

'|'  What purpose does it serve?

 

In this circumstance it doesn't signify anything more than to be a separator for each array value.

 

Generally the pipe '|' symbol is used for the logical operator 'OR'.  Read more here:

The single pipe is used for bitwise operations (working on binary), the double pipe is used as Maq said for logical operations; the '|' in your example, as Maq also said, isn't any special syntax, it's just that character in a string.

Ah yes, thanks for pointing that out  .  You can read/learn more in the manual:
