Why does php concatenate with . instead of +?

Question

Seriously, who's the jackass who decided that . would be a better operator than +? I'm assuming this was inherited from perl. There has to be a reason they chose a cockamamie character like . instead of the logical choice (+). Anyone know what it was?

Answer 1

So that you may not accidentally add in place of concatenate.

e.g.

$x = 1;
$y = 2;
$sum = $x + $y;
but
$str = $x.$y

And $sum is 3 but $str is 12, what ever you want.

Got it?

Answer 2

In weakly typed languages like perl and php, you could perform either operation. If $a=1 and $b=2, $a + $b = 3, but $a.$b = 12.

Answer 3

php concatenate with . instead of +

reason: php was initially developed by Rasmus Lerdorf. and it was just a couple of perl scripts back then. so you got the idea, the roots of php lies in perl. thats why php concatenate with . instead of +

Answer 5

Every language has its syntax like visual basic have & for concatenation, and they take it from Perl.

Answer 6

this isn't javascript first of all. + is addiction and . is the string operator

$word = 'dog';
$new = $word .= 'food';
