using DOT before variable

[Alfraganus]

dear bros,

why we have to use "." (DOT) before and after every variable?

for example:

$color="green";

echo "my eyes' color is ".$color.";

 

thank you for your attention.

In PHP, the dot is the concatenation operator. See this link: http://www.w3schools.com/php/php_operators.asp ...scroll down to String Operators.

 

If you don't want to use the dot operator to concatenate, you can use double quotes with the variable included like the following: echo "My eye color is $color"; Because of being in double quotes, PHP displays(parses) the value of the variable $color. The output is: My eye color is green.
