small php issue regards readfile and convert "\n" to <br />

hello i met some problem when i use readfile function. i have a text file a.txt with the following content:

1234567
abcdefg
ABCDEFG

and i used readfile("a.txt") to read the file and print the content on the screen but i got:

1234567 abcdefg ABCDEFG

but when i read the source file in browser it is:

1234567
abcdefg
ABCDEFG

so i suppose the browsers explain signal "\n" as a blank space and i should convert those "\n" to <br /> in the output html file. so i used nl2br function to do it:

nl2br(readfile("a.txt"));

but, still i got same issue, without seeing any <br /> in the browser source file. so i am really confused. anyone who can tell me how to get the correct result? thanks.

 

str_replace("\n", "<br>", $string);

 

still the same resualt.

 

Not 100% sure what you ment but is this what your looking for?

$filename = "file.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);

$contents = explode('/n', $contents);

for ($content in $contents){
print $content . "<br />";
}
