wohlm Posted December 22, 2009 Share Posted December 22, 2009 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.

Maq Posted December 22, 2009 Share Posted December 22, 2009 '|' 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'.

salathe Posted December 22, 2009 Share Posted December 22, 2009 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.
