php上传文件大小限制修改

在php.ini里查找
max_execution_time //允许脚本最大执行时间
默认是30秒.改为
max_execution_time = 0
0表示没有限制

file_uploads = On                                         //开启文件上传
upload_max_filesize = 50M                             //允许最大上传文件大小
post_max_size = 100M                                 //允许最大post数据大小
memory_limit = 128M                                   //单个php脚本所能申请到的最大内存空间

提示：需要保持 memory_limit > post_max_size > upload_max_filesize
