Unable to remove line break

[patawic]

<?php

$gamertag = $_GET['gamertag'];

$lines = file("http://www.xboxgamercard.net/testing/index.php?gamertag=$gamertag");

$image = imagecreatefrompng("base.png"); 

$img = imagecreatetruecolor(imagesx($image), imagesy($image));

$watermark = imagecreatefromjpeg("$lines[12]");

 

$base_width = imagesx($image);

$base_height = imagesy($image);

 

$watermark_width = imagesx($watermark); 

$watermark_height = imagesy($watermark);

 

$dest_x = $base_width - $watermark_width - 0; 

$dest_y = $base_height - $watermark_height - 0;

 

imagecopy($img, $image, 0, 0, 0, 0, $base_width, $base_height);

imagecopy($img, $watermark, $dest_x, $dest_y, 10, 10, $watermark_width, $watermark_height);

 

header ("Content-type: image/png");

 

Imagepng ($img);

imagedestroy($img); 

?>

 

Im having an issue with my $lines[12] variable, the url works but there is an unwanted line break at the end of the file. causing this error http://xboxgamercard.net/testing/image.php?gamertag=immunise.

how can i fix this. ive tried str_replace and strip_tags

[rajivgonsalves]

change this

 

$watermark = imagecreatefromjpeg("$lines[12]");

to

 

$lines[12] = preg_replace("#[\r\n]+#", '', strip_tags($lines[12]));
$watermark = imagecreatefromjpeg($lines[12]);

I think you should instead be using the FILE_IGNORE_NEW_LINES flag in your call to file. That will remove the newline from the end of each line in the $lines array.

Myself, I see line 12 empty on every gamertag that I've tried it on.

You do know that the array begins with 0 not 1?

so it shouldd be $line[11] that you are looking for.

you can verify this by using var_dump($line)
