  • PHP: Dancing with the cURL

    HTTP Authentication with cURL in the event I’m overdrawn at the memory bank.

    $ch = curl_init();
$url = "http://myurl.com/plah.php?foo=value";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, "user:pass");
curl_exec ($ch);
curl_close ($ch);

  • PHP: Locator script

    When asked to write a store location program in less than an hour, I developed this little utility. It uses my own MySQL class and clean() function which parses the POST/GET variables for any nastiness that might have occurred. 

    include('includes/class.mysql.php');
include('includes/functions.php');

clean(); // Clean up $_REQUEST for SQL injection
$mysql = new mysql();
$zip = $_REQUEST[zip];
$city = $_REQUEST[city];
$digits = strlen($zip);
//echo "Count: $digits
    ";

echo "\n\n";
echo "\n";
while($i<1) {
        $q = ($zip) ? $mysql->query("SELECT * FROM stores WHERE zip LIKE '$zip%'") : $mysql->query("SELECT * FROM stores WHERE state = '$_REQUEST[state]' AND city LIKE '%$city%' ORDER BY zip ASC");
        if(mysql_num_rows($q)) {
                while($r = mysql_fetch_assoc($q)) {
                        echo "\t\n";
                        echo "\t\t".trim($r[chain])."\n";
                        echo "\t\t".trim($r[store])."\n";
                        echo "\t\t".trim($r[location])."\n";
                        echo "\t\t".trim($r[city])."\n";
                        echo "\t\t".trim($r[state])."\n";
                        echo "\t\t".trim($r[zip])."\n";
                        echo "\t\n";
                }
                $i++;
        } else if (strlen($zip) > 1) {
                $zip = substr($zip, 0, strlen($zip) - 1);
        } else {
                $i = 1;
        }
}
echo "\n";
echo "\n";

  • PHP: TrueType bounding box with GD

    Just a snippet to print out the values in a bounding box. print_r’s simple outline format just makes it easier to visualize. 

    <?php
$im = imagecreatetruecolor(800,600);
$arr = imagettfbbox(30,0,'fonts/arial.ttf','this is a long string of text!');
print_r($arr);
?>

  • PHP: transparent PNG over JPEG

    <?php
header("Content-type: image/jpeg");
$im = imagecreatetruecolor(800,600); // main image output
$im2 = imagecreatefromjpeg('image1.jpg');
$im3 = imagecreatefrompng('../images/template3.png');

imagecopymerge($im,$im2,360,186,0,0,800,600,100);
imagecopy($im,$im3,0,0,0,0,800,600);

imagejpeg($im);
imagedestroy($im);
imagedestroy($im2);
imagedestroy($im3);
?>
