adding to a string value using... &$var ?

[jasonc]

I have seen somewhere that you can add to a string like so

 

$var = "text";

 

 

or

 

 

$string ="var";

&$var = "text";

 

it is the latter that I am wanting to know more about.

Never done it that way... I've always done.. Interested in seeing the other one your talking about..

$var = '1';
$var .= '2';

echo $var; //echo's 12

What you have provided is still incorrect, but if you're wondering about the ampersand then it's used for references.

 

$foo = 'foo bar';

$bar = &$foo;
$bar = 'bar foo';

echo $foo; // will output bar foo
