Simple Quetion, Read top line of text file... HELP [nooooob]

[thegreatone]

Ok, all i want this to do is read the top line of a file called Song.txt (which resides in the same directory)
i want it to be the text attribute of the coding, i hope you understand what i mean.

This should be really simple, but i am a total noobie to this, and i am using the GDI library to draw an image.

heres my code, i hope you can edit it to work. thanks.

<?php
// You need this to make sure that browsers read this as an image
header("Content-type: image/png");

$font_size  = 14;

// Text to output
$text  = $_GET['text'];

// Location of the base graphic
$base = $_GET['image'];

// Colors in RGB format for the TEXT
// This is NOT Hex (#) format
// To get the RGB values for a color, use something like photoshop
$r     = "255";
$g     = "255";
$b     = "255";

// Code to create the actual image
$im    = imagecreatefrompng($base);
$color = imagecolorallocate($im, $r, $g, $b);

// X-Position of Text [directly in middle with this code]
// Change the 6 to a different value based on the font you pick later on
$px    = (imagesx($im) - 15 * strlen($text)) / 2;

// Y-Position of Text
// Change this based on the X-Position and Font if needed
$py    = '18';

// Font (1 = small/pixel, 2 = similar to verdana, 3 = large/bold, etc)
$font  = $_GET['font'];

imagettftext($im, $font_size, 0, $px, 30, $black, $font, $text);
imagepng($im);
imagedestroy($im);
?>

thankyou.

$lines = file('Song.txt');
// $lines[0] is the top line of a file called Song.txt 

Can also be a URL

I'm probably missing what you mean since you mentioned graphics.

Actually, I think you are trying to extract text from a graphics file, but won't it just be pixels as the input? I'm doing something similar so I'd like to know the solution you come up with.

If the file is only one line in size then Pehnix's method is ideal and easiest. If you have a large file with many lines however, it is better to use the method below as it does not require that the entire file be loaded into memory:

if ($hwnd = fopen($file, 'rb')) {
    $line1 = trim(fgets($hwnd));
    
    fclose($hwnd);
} 

Remember that in both examples you should use the rtrim() function to strip the new line characters from the end of the text.

Thanks, the $lines[0] worked very well for me

I just have one problem, i have php_gd.dll and it works fine, but whats the advantage of php_gd2.dll ???

I also have an issue with the PNG image being created, its really bad, and the colours are rubbish, is there anyway to produce higher quality images ?
