concat a for loop - php

I want to concatenate a for loop

$stringd = "xxx". for($i=1;$i<=$_POST['cc'];$i++) { echo $_POST[$i]." ";} . "hello";

The ab开发者_StackOverflow社区ove throws an error; how do I write one?

You first have to initialize your string :

$stringd = "xxx";

Then, loop, concatenating at the end of that variable :

for($i=1;$i<=$_POST['cc'];$i++) {
    $stringd .= $_POST[$i]." ";
}

And, finally, end with the last part :

$stringd .= "hello";

But you cannot do all (especially, the loop) that in a single operation.

$stringd = "xxx";
for($i=1;$i<=$_POST['cc'];$i++) 
{ 
   $stringd .= $_POST[$i]." ";
} 
$stringd .= "hello";

I believe this is what you're looking for:

$stringd = "xxx";

for($i=1;$i<=$_POST['cc'];$i++) 
{ 
   stringd.= $_POST[$i]." ";
} 

$stringd .= "hello";
