The bug reported by 'michi at marel dot at' also exists in PHP version 5.1.1. This functions just works with vertical lines!
imagedashedline
说明
bool imagedashedline ( resource image, int x1, int y1, int x2, int y2, int color )反对使用本函数。应该用 imagesetstyle() 和 imageline() 的组合替代之。

I make my own dashedline:
<?
for($l=50;$l<=550;$l+=5)
{
if($da == 0) { $da = 1; }
elseif($da == 1){
imageline($bild,$l,50,$l+5,50,$green);
$da = 0; }
}
?>
$l is the x-value
and we have a dashed line :)

There's a bug till PHP 4.0.4 in this function. You can only draw vertical dashed lines. To draw other dashed lines you can set <ImageSetStyle> to a special dashed line and draw it by <ImageLine>.
Sample code:
<?php
function MDashedLine($image, $x0, $y0, $x1, $y1, $fg, $bg)
{
$st = array($fg, $fg, $fg, $fg, $bg, $bg, $bg, $bg);
ImageSetStyle($image, $st);
ImageLine($image, $x0, $y0, $x1, $y1, IMG_COLOR_STYLED);
}
?>
