php配置-解决大数据超多字段的POST方式提交无法完全接受的问题

例如：在盘点表的数据提交中出现了POST大量数据超多字段的将近2000个字段，部分字段没有接受；修改方法为修改php.ini

将max_input_var调大，该值默认为1000

max_input_vars = 5000

相近的配置还有：

max_execution_time = 600
max_input_time = 600
memory_limit = 32m
file_uploads = on
upload_tmp_dir = /tmp
upload_max_filesize = 32m
post_max_size = 32m

在nginx中相近的配置有：

keepalive_timeout  60;
send_timeout 3m;
client_max_body_size 500m;

例如：修改上传图片的最大限制，避免entity too large的错误

首先，将php的upload_max_filesize 和 post_max_size 调大

再将nginx的 client_max_body_size 调大

或将apache的LimitRequestBody调大

//php配置
max_execution_time = 600　　　　　　　　//设置页面访问超时时间为600s
max_input_time = 600　　　　　　　　　　//设置GET和POST等接收数据的最大超时时间为600s
file_uploads = on
upload_tmp_dir = /tmp
upload_max_filesize = 50m　　　　//设置为50M
post_max_size = 50m            //设置为50M
//nginx配置
client_max_body_size 50M     //设置为50M
//apache配置
LimitRequestBody 50 * 1024 * 1000　　　　//设置为50M

例如：Allowed memory size of 134217728 bytes exhausted (tried to allocate 32 bytes)

注意这个不是因为memory_limit参数的问题，即使memory_limit配置的最大也有可能出问题；关键在于代码循环中unset变量；

我的php.ini中memory_limit原来为128M，报了这个错误；后来我将memory_limit调成1024M还是报同样的错误。
