Question

大家好我的系统有问题，我现在正在工作。
我正在通过ajax发送数据。问题是，当我试图回显我在php文件中发送的数据时，有undefying个变量的错误，但当我在php中进行var_dumping时它向我展示了这个array。

array（20）{[“------ WebKitFormBoundaryaw2Fqe4TLPU8WGtM   Content-Disposition：_form-data; name“] =＆gt; string（948）”“pimage”;   filename =“C：\ fakepath \ 2772.png”Content-Type：image / png？PNG   IHDRæ$？SBIT 30 O？   pHYsp P | {?? tEXtSoftwarewww.inkscape.org ?? string（0）“”[“'（）* _， - _ / 0123456789：;＆lt;”] =＆gt;串（415）   “＆GT; @ ABCDEFGHIJKLMNOPQRSTUVWXYZ [\] ^ _`ABCDEFGHIJKLMNOPQRSTUVWXYZ {|}〜????????????????????????????????? ?????????????????????????????????????????????????? ?????????????????????????????????????????? 6？“??
