Base class for other PEAR classes. Provides rudimentary
emulation of destructors.
If you want a destructor in your class, inherit PEAR and make a
destructor method called _yourclassname (same name as the
constructor, but with a "_" prefix). Also, in your constructor you
have to call the PEAR constructor: $this->PEAR();.
The destructor method will be called without parameters. Note that
at in some SAPI implementations (such as Apache), any output during
the request shutdown (in which destructors are called) seems to be
discarded. If you need to get any debug information from your
destructor, use error_log(), syslog() or something similar.
IMPORTANT! To use the emulated destructors you need to create the
objects by reference: $obj =& new PEAR_child;

| __construct($error_class = null) X-Ref |
| Constructor. Registers this object in $_PEAR_destructor_object_list for destructor emulation if a destructor object exists. param: string $error_class (optional) which class to use for return: void |
| PEAR($error_class = null) X-Ref |
| Only here for backwards compatibility. E.g. Archive_Tar calls $this->PEAR() in its constructor. param: string $error_class Which class to use for error objects, |
| _PEAR() X-Ref |
| Destructor (the emulated type of...). Does nothing right now, but is included for forward compatibility, so subclass destructors should always call it. See the note in the class desciption about output from destructors. return: void |
| getStaticProperty($class, $var) X-Ref |
| If you have a class that's mostly/entirely static, and you need static properties, you can use this method to simulate them. Eg. in your method(s) do this: $myVar = &PEAR::getStaticProperty('myclass', 'myVar'); You MUST use a reference, or they will not persist! param: string $class The calling classname, to prevent clashes param: string $var The variable to retrieve. return: mixed A reference to the variable. If not set it will be |
| registerShutdownFunc($func, $args = array() X-Ref |
| Use this function to register a shutdown method for static classes. param: mixed $func The function name (or array of class/method) to call param: mixed $args The arguments to pass to the function return: void |
| isError($data, $code = null) X-Ref |
| Tell whether a value is a PEAR error. param: mixed $data the value to test param: int $code if $data is an error object, return true return: bool true if parameter is an error |
| setErrorHandling($mode = null, $options = null) X-Ref |
| Sets how errors generated by this object should be handled. Can be invoked both in objects and statically. If called statically, setErrorHandling sets the default behaviour for all PEAR objects. If called in an object, setErrorHandling sets the default behaviour for that object. param: int $mode param: mixed $options return: void |
| expectError($code = '*') X-Ref |
| This method is used to tell which errors you expect to get. Expected errors are always returned with error mode PEAR_ERROR_RETURN. Expected error codes are stored in a stack, and this method pushes a new element onto it. The list of expected errors are in effect until they are popped off the stack with the popExpect() method. Note that this method can not be called statically param: mixed $code a single error code or an array of error codes to expect return: int the new depth of the "expected errors" stack |
| popExpect() X-Ref |
| This method pops one element off the expected error codes stack. return: array the list of error codes that were popped |
| _checkDelExpect($error_code) X-Ref |
| This method checks unsets an error code if available param: mixed error code return: bool true if the error code was unset, false otherwise |
| delExpect($error_code) X-Ref |
| This method deletes all occurences of the specified element from the expected error codes stack. param: mixed $error_code error code that should be deleted return: mixed list of error codes that were deleted or error |
| raiseError($message = null,$code = null,$mode = null,$options = null,$userinfo = null,$error_class = null,$skipmsg = false) X-Ref |
| This method is a wrapper that returns an instance of the configured error class with this object's default error handling applied. If the $mode and $options parameters are not specified, the object's defaults are used. param: mixed $message a text error message or a PEAR error object param: int $code a numeric error code (it is up to your class param: int $mode One of PEAR_ERROR_RETURN, PEAR_ERROR_PRINT, param: mixed $options If $mode is PEAR_ERROR_TRIGGER, this parameter param: string $userinfo If you need to pass along for example debug param: string $error_class The returned error object will be param: bool $skipmsg If true, raiseError will only pass error codes, return: object a PEAR error object |
| throwError($message = null, $code = null, $userinfo = null) X-Ref |
| Simpler form of raiseError with fewer options. In most cases message, code and userinfo are enough. param: mixed $message a text error message or a PEAR error object param: int $code a numeric error code (it is up to your class param: string $userinfo If you need to pass along for example debug return: object a PEAR error object |
| staticPushErrorHandling($mode, $options = null) X-Ref |
| No description |
| staticPopErrorHandling() X-Ref |
| No description |
| pushErrorHandling($mode, $options = null) X-Ref |
| Push a new error handler on top of the error handler options stack. With this you can easily override the actual error handler for some code and restore it later with popErrorHandling. param: mixed $mode (same as setErrorHandling) param: mixed $options (same as setErrorHandling) return: bool Always true |
| popErrorHandling() X-Ref |
| Pop the last error handler used return: bool Always true |
| loadExtension($ext) X-Ref |
| OS independant PHP extension load. Remember to take care on the correct extension name for case sensitive OSes. param: string $ext The extension name return: bool Success or not on the dl() call |
| _PEAR_call_destructors() X-Ref |
| No description |
Class: PEAR_Error - X-Ref
Standard PEAR error class for PHP 4This class is supserseded by {@link PEAR_Exception} in PHP 5
| __construct($message = 'unknown error', $code = null,$mode = null, $options = null, $userinfo = null) X-Ref |
| PEAR_Error constructor param: string $message message param: int $code (optional) error code param: int $mode (optional) error mode, one of: PEAR_ERROR_RETURN, param: mixed $options (optional) error level, _OR_ in the case of param: string $userinfo (optional) additional user/debug info |
Class: PEAR_Exception - X-Ref
| PEAR_Error($message = 'unknown error', $code = null,$mode = null, $options = null, $userinfo = null) X-Ref |
| Old syntax of class constructor for backward compatibility. |
| getMode() X-Ref |
| Get the error mode from an error object. return: int error mode |
| getCallback() X-Ref |
| Get the callback function/method from an error object. return: mixed callback function or object/method array |
| getMessage() X-Ref |
| Get the error message from an error object. return: string full error message |
| getCode() X-Ref |
| Get error code from an error object return: int error code |
| getType() X-Ref |
| Get the name of this error/exception. return: string error/exception name (type) |
| getUserInfo() X-Ref |
| Get additional user-supplied information. return: string user-supplied information |
| getDebugInfo() X-Ref |
| Get additional debug information supplied by the application. return: string debug information |
| getBacktrace($frame = null) X-Ref |
| Get the call backtrace from where the error was generated. Supported with PHP 4.3.0 or newer. param: int $frame (optional) what frame to fetch return: array Backtrace, or NULL if not available. |
| addUserInfo($info) X-Ref |
| No description |
| __toString() X-Ref |
| No description |
