Use PHP's GD library to draw a horizontal dashed line solution

Use PHP's GD library to draw horizontal dashed lines
Run the following code

PHP Code

  
   $img = imagecreatetruecolor, $white = Imagecolorallocate ($img, 255, 255, 255); Imagedashedline ($img, 20, 20, 500, ($white), Imagedashedline ($img, (a), $white), header ("Content-type:image/jpeg"), imagejpeg ($IMG); Imagedestroy ($IMG);

You will find that the vertical dashed line is fine, but the horizontal dashed line is not displayed. Who knows why?


------Solution--------------------

PHP code

 $img = Imagecreatetruecolor (+); $white = Imagecolorallocate ($img, 255, 255, 255); $red = Imagecolorallocate ($img, 255, 0, 0); $style = Array ($red, $red, $red, $red, $red, $white, $white, $white, $white, $white); Imagesetstyle ($img, $style); Imageline ($img ("Content-type:image/jpeg"); imagejpeg ($img); Imagedestroy ($img); 
------Solution--------------------
 The bug reported by ' Michi @ Marel dot at ' also exists in PHP version 5.1.1. This functions just works with vertical lines! 5.1.1 version found the bug, against the use of this function. The 
------solution should be replaced with the combination of Imagesetstyle () and Imageline ()--------------------
 This functions just works with vertical Lines! This function can only draw a vertical line! 
------Solution--------------------
 Indeed, the GD library can only draw vertical dashed lines!
