Dot before = in variable?

[aximbigfan]

I have seen this a few times. What exactly does it do?

Example: $variable .= (something)

 

Thanks,

It's a shorthand for

<?php
$variable = $variable . 'something';
?>

Just like "+=", "-=", etc.

if you have a string like

 

$var = "My Dog Is:";

 

And you want to add a next word to that, its the same as $var = "My Dog Is:" .  " Happy";

 

but instead

 

$var = "My Dog Is:";
$var .= " Happy";

 

or

 

$var = "My Dog Is:";
$mood = " happy";
$var .= $mood;

Oh, ok. Thanks!
