字符串变量HtmlString。变量值不确定。但都存在 var pictree = [字符串1] 和 。 

如何把 字符串1 里各''里的内容和 字符串2 连接起来组成一个新的字符串？


在线等。 第一次接触PHP。谢谢老师！！

html;
preg_replace('/var pictree = \[([^\]]*)\]/e',"\$s='$1'",$HtmlString);
$arr=explode(',',str_replace("'",'',$s));
$str=preg_match('/id="thePath" value="(.*?)"/s',$HtmlString,$m);
foreach($arr as &$v) $v=$m[1].$v ;
print_r($arr);
