Here's a short explanation of the configuration directives.

soap.wsdl_cache_enabled boolean

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_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.

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.
