I'm trying to create a script that writes text to an image.
CODE header("Content-type: image/png"); $_phrases = array( "Test 1", "Test 2", "Test 3", "Test 4", "etc." ); $_rand_phrase = $_phrases[rand(0,count($_phrases)-1)]; $_image = imagecreatefrompng("gmail.png"); $_user_width = imaagettfbbox(9,0,"tahoma.ttf",$_rand_phrase); $_x_value = (200-($user_width[2] + 113)); $_color = imagecolorallocate($_image, 165, 164, 164); imagettftext($_image, 9, 0, $_x_value, 16, $_color, "tahoma.ttf", $_rand_phrase); imagepng($_image); imagedestroy($_image); I can't see what I'm doing wrong.. I know it should work, I'm making a dumb mistake of some sort. Can anyone help? This post has been edited by microscopic^earthling: Jul 16 2005, 12:35 PM |

You spelled imagettfbbox with an extra a (imaagettfbbox).
And why do you have all your variables start with underscores? You need them only when you want numbers at the beginning of a varible, like $_42lasljwoie. Are you trying to make the variables starting with numbers to look the same as variables starting with letters? The underscores don't cause a problem, but I'm just curious. |

QUOTE(szupie @ Jul 17 2005, 04:53 AM) And why do you have all your variables start with underscores? It's a coding convention, I've seen that in few other places too. I don't quite get the point, but that's not the first time... |

I've seen that coding convention before but only for private methods, and for predefined global variables like $_GET, $_POST, $_SERVER, $_REQUEST, and so on
 I didn't know it was used for userdefined variables too  that's new for me
