there is a soap config section in your php.ini file, which control the wsdl access cache, may be shown as:

[soap] 
; Enables or disables WSDL caching feature. 
soap.wsdl_cache_enabled=1 ; 
Sets the directory name where SOAP extension will put cache files. 
soap.wsdl_cache_dir="/tmp" 
; (time to live) Sets the number of second while cached file will be used ; instead of original one.  
soap.wsdl_cache_ttl=86400

if wsdl file cache is enabled, it may cause this problem when changing wsdl URI in php code. in this example, you can just delete file start with wsdl- under /tmp directory. or you just set soap.wsdl_cache_enabled=0; and soap.wsdl_cache_ttl=0; PHP will fetch the wsdl file every-time you visit the page.
