Really dumb question ...

[LuciBKen]

Could any one tell me the real difference in using .= or just =?

 

[mkosmosports]

.= will concatenate (join) the already existing string with whatever you specify it to equal...very useful...

 

So for example,

 

$text = "hello";

 

$text .= " ,my name is";

 

echo($text), will now be hello ,my name is...

<?php

$strvar = "Line one\n";

echo $strvar;

/*Will echo...

Line one

*/
?>

 

<?php

$strvar = "Line one\n";
$strvar .= "Line two\n";
$strvar .= "Line three\n";

echo $strvar;

/*Will echo...

Line one
Line two
Line three

*/

?>

.= is used for adding to an existing variable

 

$var = "hello ";
$var .= "world";
// hello world

 

= redefines the entire variable

 

$var = "hello ";
$var = "world";
// world
