求一段正则提取代码
$str='求一段正则提取代码解决思路';

如以上字符串，将里面的超链接全部提取出来，如果此链接中有类似于 "id=9694595974"(其中id=后面的数字是系统自动生成的，而且数字后面跟的参数有时有 ，有时没有，如上例中的（&ali_refid=a3_620362_1007:1102370186:7:46702465U84y78608587678s868v3I:7178ec8bae50aef3a187075f995ad009&ali_trackid=1_7178ec8bae50aef3a187075f995ad009），可能有有可能没有)，将此链接替换为go.php?id=9694595974,并将替换后的链接放回原处,如果原链接没有类似于"id=9694595974"的字符串，将此链接替换为”#“,并放回原处(此字符串中含有多个"id=9694595974"的超链接和多个不含"id=9694595974"的超链接),
