Generate Text Image using PHP

Generating Text Image Logo using PHP is quite simple and straight forward. May be the following code might help you to create logos, captcha, titles etc…

 
if (!(file_exists("logophilip.png")))          // Checks file exist or not 
{
  $imgvalue = "Philip Tiju Abraham";           // Assign some text for the logo
  $font_file = 'font.ttf';                     // font name/path
  $pic=ImageCreate(500,70);                    // Define the size of the image a x b            
  $col1=ImageColorAllocate($pic,217,209,188);  // Background
  $col2=ImageColorAllocate($pic,79,79,79);     // Fontcolor
  ImageFilledRectangle($pic,1,1,100,100,$col1); 
  ImageFtText($pic, 35, 0, 0, 50, $col2, $font_file, $imgvalue);
  ImagePNG($pic,"logophilip.png");             // Thats it done...
  ImageDestroy($pic);                          
}

I don’t think I need to explain how it works. Just place the code and enjoy. Make sure you have the font in the same folder or update $font_file with respective path.

Add Gravatar to your web sites using PHP & C#

Gravatar (an abbreviation for globally recognized avatar) is a service for providing globally unique avatars which was created by Tom Preston-Werner. On Gravatar, users can register an account based on their email address, and upload an avatar to be associated with the account. Gravatar plugins are available for popular blogging software; when the user posts a comment on such a blog that requires an e-mail address, the blogging software checks whether that e-mail address has an associated avatar at Gravatar.

PHP:

 
function GetAvatar($email) 
{ 
   $emailMD5 = md5($email); 
   $gravatarURL = "http://www.gravatar.com/avatar/" . $emailMD5 . ".jpg"; 
   $html="<img src='$gravatarURL' />"; return $html; 
}

C#:

 
public string GetAvatar(string Email) 
{ 
   string emailMd5 = Utilities.Encryption.MD5.ComputeHash(Email.Trim().ToLower()).ToLower(); 
   string gravatarURL = "http://www.gravatar.com/avatar/" + emailMD5 + ".jpg"; 
   string html = "<img src='" + $gravatarURL + "' />"; return html; 
}
