It's a string operator used to concatenate strings. http://php.net/manual/en/language.operators.string.php

[Psycho]

$foo = 'b';
$foo .= 'a'; //Concatenate 'a' to current value
$foo .= 'r'; //Concatenate 'r' to current value

echo $foo; //Output: bar

$foo = 'b';
$foo = 'a'; //Replace current value with 'a'
$foo = 'r'; //Replace current value with 'r'

echo $foo; //Output: r
