- 6. IIS Execution Models Extension to CGI allowing reuse of a process. Advantages Easy to Configure Faster than CGI More stable than PHP on ISAPI Can run non- thread-safe versions of PHP Invokes a process for each request. Advantages Easy to Configure Stable Execution Disadvantages Slow due to I/O Overhead of Process Creation Loaded as extension in process. Advantages Better Performance Disadvantages Many PHP Applications are not Thread-Safe

- PHP Opcode Cache PHP is a script processing engine that reads an input stream of data that contains text and/or PHP instructions and produces another stream of data, most commonly in the HTML format. This means that on a Web server, the PHP engine reads, parses, compiles, and executes a PHP script each time that it is requested by a Web client. The reading, parsing, and compilation operations put additional load on the Web server’s CPU and file system and thus affect the overall performance of a PHP Web application. The PHP bytecode (opcode) cache is used to store the compiled script bytecode in shared memory so that it can be reused by the PHP engine for subsequent executions of the same script. File Cache Even with the PHP bytecode cache enabled, the PHP engine has to accesses the script files on a file system. When PHP scripts are stored on a remote universal naming convention (UNC) file share, the file operations introduce a significant performance overhead. The Windows Cache Extension for PHP includes a file cache that is used to store the content of the PHP script files in shared memory, which reduces the amount of file system operations performed by PHP engine. Relative File Path Cache PHP scripts very often include or operate with files by using relative file paths. Every relative file path has to be converted to an absolute file path by the PHP engine. When a PHP application uses many PHP files and accesses them by relative paths, the operation of resolving relative paths to absolute paths may have a negative impact on the application’s performance. The Windows Cache Extension for PHP provides a relative file path cache, which is used to store the mappings between relative and absolute file paths, thereby reducing the number of relative path resolutions that the PHP engine has to perform.
- Consuming without WSDL and with WSDL
- definitions The definitions element must be the root element of all WSDL documents. It defines the name of the web service, declares multiple namespaces used throughout the remainder of the document, and contains all the service elements described here. types The types element describes all the data types used between the client and server. WSDL is not tied exclusively to a specific typing system, but it uses the W3C XML Schema specification as its default choice. If the service uses only XML Schema built-in simple types, such as strings and integers, the types element is not required. A full discussion of the types element and XML Schema is deferred to the end of the chapter. message The message element describes a one-way message, whether it is a single message request or a single message response. It defines the name of the message and contains zero or more message part elements, which can refer to message parameters or message return values. portType The portType element combines multiple message elements to form a complete one-way or round-trip operation. For example, a portType can combine one request and one response message into a single request/response operation, most commonly used in SOAP services. Note that a portType can (and frequently does) define multiple operations. binding The binding element describes the concrete specifics of how the service will be implemented on the wire. WSDL includes built-in extensions for defining SOAP services, and SOAP-specific information therefore goes here. service The service element defines the address for invoking the specified service. Most commonly, this includes a URL for invoking the SOAP service.
