--------------------------
说明：在网上找了半天发现全是何志强的那段代码，我也就拿来改了一下用上了。其中加入了一部分自己的内容，只是还不太清楚如何规定图片等元素的大小。我曾经把 function img($start,$end,$value){
$trim_value=trim($value);
if ((strtolower(substr($trim_value,0,7))!="http://") or ($this->urlcheck->check($trim_value)))
return @#<img src="@#.$trim_value.@#"></img>@#;
else return @#[@#.$start.@#]@#.$value.@#[/@#.$end.@#]@#;
}
改为：
function img($start,$end,$value){
$trim_value=trim($value);
if ((strtolower(substr($trim_value,0,7))!="http://") or ($this->urlcheck->check($trim_value)))
{
$pisces=explode(" ",$start);
if(!is_int($pisces[1]) || !!is_int($pisces[2]))
return @#<img src="@#.$trim_value.@#" width=$pisces[1] height=$pisces[2]></img>@#;
else
return @#<img src="@#.$trim_value.@#"></img>@#;
}
else return @#[@#.$start.@#]@#.$value.@#[/@#.$end.@#]@#;
}
但由于对前面的正则表达式不熟悉没成功。
