求以下php混淆方式實現代碼

${"GLOBALS"}["xcxpph"] = "protectedChars";${"GLOBALS"}["nxaluweq"] = "tempUrl";${"GLOBALS"}["bpqvmkve"] = "domainLength";${"GLOBALS"}["emwhettg"] = "tempURLs";${"GLOBALS"}["puhwuyrf"] = "partNum";${"GLOBALS"}["ieihymjca"] = "targetURL";${"GLOBALS"}["atndyantqovv"] = "targetDomain";${"GLOBALS"}["vhgestq"] = "Atag";${"GLOBALS"}["vtgjjko"] = "the_list_url";${"GLOBALS"}["ilxxjlskus"] = "contextOptions";${"GLOBALS"}["pxsqemhbaxs"] = "headerstrings";${"GLOBALS"}["nfqwlim"] = "tempValue";

function xmltext()    {        ${"GLOBALS"}["koqdbjn"] = "ret";        $xrspsjeehifm = "ret";        ${"GLOBALS"}["xlsyxp"] = "ret";        ${${"GLOBALS"}["qzawbrpom"]} = $this->innertext();        ${${"GLOBALS"}["xlsyxp"]} = str_ireplace("", "", ${$xrspsjeehifm});        ${"GLOBALS"}["edrmol"] = "ret";        ${${"GLOBALS"}["qzawbrpom"]} = str_replace("", "", ${${"GLOBALS"}["koqdbjn"]});        return ${${"GLOBALS"}["edrmol"]};    }

以上為截取的部分代碼，跪求大神指點

回複內容：
