I am using php 5.1.2 on a winxp machine. I was  getting into the TrueType fonts and wanted to see which ones would look best incorporated into web images. So I created the following script that prints out samples of all the TrueType fonts found in my C:\Windows\Fonts directory. The script takes only one request parameter - 'fsize'. It stands for font-size and lets you see each font in any size you wish -- I limited it to values between 5 and 48. Hope this helps someone other than me :)

I apologize in advance if any of my code is not the prettiest-written php code even seen -- I have only been coding in php for the past week (I'm a perl-guy usually).

<?php
    list($x, $y, $maxwidth) = array(0, 0, 0);

    $fsize = (int)$_REQUEST['fsize'];
    if ($fsize < 5 or $fsize > 48) $fsize = 8;

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

    // don't know how wide or tall the font samples will be.
    // create a huge image for now, we'll copy it smaller
    // later when we know how large the image needs to be.
    $im = imagecreate(1000, 20000) or die('could not create!');
    $clr_white = imagecolorallocate($im, 255, 255, 255);
    $clr_black = imagecolorallocate($im, 0, 0, 0);

    $font_path = "C:/Windows/Fonts/";
    $dh = opendir($font_path);
    while (($file = readdir($dh)) !== FALSE) {
        // we're only dealing with TTY fonts here.
        if (substr(strtolower($file), -4) != '.ttf') continue;

        $str = "Sample text for '$file'";
        $bbox = imagettfbbox(
            $fsize, 0, "{$font_path}{$file}", $str
        );
        $ww = $bbox[4] - $bbox[6];
        $hh = $bbox[1] - $bbox[7];

        imagettftext(
            $im, $fsize, 0, $x, $y,
            $clr_black, "{$font_path}{$file}", $str
        );

        $y += $hh + 20;
        if ($ww > $maxwidth) $maxwidth = $ww;
    }

    closedir($dh);

    // ok, now we can chop off the extra space from the
    // 1000 x 20000 image.
    $im2 = imagecreate($maxwidth + 20, $y);
    imagecopyresized(
        $im2, $im, 0, 0, 0, 0, $maxwidth + 20,
        $y, $maxwidth + 20, $y
    );
    imagejpeg($im2);
    imagedestroy($im);
    imagedestroy($im2);
