这些函数的行为受 php.ini 中的设置影响。
| 名字 | 默认 | 可修改范围 | 更新日志 |
|---|---|---|---|
| soap.wsdl_cache_enabled | 1 | PHP_INI_ALL | |
| soap.wsdl_cache_dir | /tmp | PHP_INI_ALL | |
| soap.wsdl_cache_ttl | 86400 | PHP_INI_ALL | |
| soap.wsdl_cache | 1 | PHP_INI_ALL | |
| soap.wsdl_cache_limit | 5 | PHP_INI_ALL |
这是配置指令的简短说明。
soap.wsdl_cache_enabled
integer
Enables or disables the WSDL caching feature.
soap.wsdl_cache_dir
string
Sets the directory name where the SOAP extension will put cache files.
soap.wsdl_cache_ttl
integer
Sets the number of seconds (time to live) that cached files will be used instead of the originals.
soap.wsdl_cache
integer
If soap.wsdl_cache_enabled is on, this setting
determines the type of caching. It can be any of:
WSDL_CACHE_NONE (0),
WSDL_CACHE_DISK (1),
WSDL_CACHE_MEMORY (2) or
WSDL_CACHE_BOTH (3). This can
also be set via the options array in the
SoapClient or SoapServer
constructor.
soap.wsdl_cache_limit
integer
Maximum number of in-memory cached WSDL files. Adding further files into a full memory cache will delete the oldest files from it.
Keep in mind if you have memory cache enabled that even if you use an updated WSDL file, it will still be using the one in memory. If you download the WSDL files yourself, avoid using memory cache as you will have no control over it, or set the TTL to a small value (default is 1 day).
Please note that these three ini settings will also affect the behaviour of your soap server (and clients as well) :
1. default_socket_timeout default 60 secs
Large or slow requests to your soap server or long processes at your soap server will return soap fault after 60 secs like : Error Fetching http headers.
2. max_execution_time default 30 secs
This can be the next bottleneck (but only when your default_socket_timeout is larger then this setting). Your soap server will not return anything, no faults no output, just an empty string.
3. memory_limit default 128M
Will throw fatal errors when the soap server script itself has low memory or will let your services return empty strings when the data it processes puts memory usage over this limit.
Other max POST settings luckily (but a bit suprisingly to me) have _no_ effect for your soap server. Those are :
max_input_time
max_input_nesting_level
max_input_vars
post_max_size
suhosin.post.max_array_depth
suhosin.post.max_array_index_length
suhosin.post.max_name_length
suhosin.post.max_totalname_length
suhosin.post.max_vars
suhosin.post.max_value_length
If you want to dissable WSDL-caching, you can do so with
<?php
ini_set('soap.wsdl_cache_enabled', '0');
ini_set('soap.wsdl_cache_ttl', '0');
?>
However you must do this before creating a SOAP object (soap_client or soap_server).
Changing the settings like above does not have any effect on already existing soap-objects.
