求问关于php 混淆字符+eval的解密构思。希望xuzuning等高手来帮忙

//function 在上面//定义了一个fun($var1,$var2='');大体意思是先先把$var1 base64还原 然后reutren ~取补数。再判断var2是否有值，下面那个好像没读懂 最后是 rerun aaa^bbb;(互斥)//下面加密了一串变量//放在一个数组中//数组的话，我后面的压缩包里面有个detempb可以弄出来，好像显示正确preg_match('正则表达式（我没有还原出来，还是还原错了感觉不对）',eval(gzuncompress(base64_decode(加密字符串穿))), ‘这里好像是一串数字’)
