Reading from a .txt file - concatenate - echoing content puts a space in automatically?

Question

I'm reading content from a text file which I'm showing on a page later, this is my code:

$lines = file("content.txt");
$i=1;
foreach($lines  as $line ){

$var["line" . $i] = $line;
$i++;
}
extract($var);

The text file includes content in this format:

bla1
bla2

and so on, there's no space behind the domains just a linebreak, now I want to concatenate the content and show it, so I do this:

$as1 = $line1.$line2;
echo $as1;

But instead of the expected result

Bla1Bla2

I get

Bla1 Bla2

What am I doing wrong ? I can assure that there's no space in the text file not behind nor infront of the content.

The browser renders newlines (`\n`) as spaces. Look into the source and you see it's still in a new line. — dan-lee, Jan 08 '13 at 11:53

There's no space; but unless you tell the file() function otherwise, there is a line feed at the end of each line

$lines = file("content.txt", FILE_IGNORE_NEW_LINES);

A browser will render a line feed as a space, unless inside a or block

use trim for this situation

$as1 = trim($line1).trim($line2);
echo $as1;

You could try trimming your input...

$lines = file("content.txt");
$i=1;
foreach($lines  as $line ){

$var["line" . $i] = trim($line);
$i++;
}
extract($var);
