_checkDelExpect

(

$

error_code

)

This method checks unsets an error code if available

Parameters:

mixed

error code

Returns:

bool true if the error code was unset, false otherwise private

Since:

PHP 4.3.0

Definition at line 384 of file PEAR.php.

Here is the caller graph for this function:

_PEAR

(

)

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.

public

Returns:

void

Definition at line 187 of file PEAR.php.

delExpect

(

$

error_code

)

This method deletes all occurences of the specified element from the expected error codes stack.

Parameters:

mixed

$error_code

error code that should be deleted

Returns:

mixed list of error codes that were deleted or error public

Since:

PHP 4.3.0

Definition at line 411 of file PEAR.php.

Here is the call graph for this function:

expectError

(

$

code = '*'

)

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

Parameters:

mixed

$code

a single error code or an array of error codes to expect

Returns:

int the new depth of the "expected errors" stack public

Definition at line 355 of file PEAR.php.

& getStaticProperty	(	$	class,
		$	var
	)

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!

public

Parameters:

string	$class	The calling classname, to prevent clashes
string	$var	The variable to retrieve.

Returns:

mixed A reference to the variable. If not set it will be auto initialised to NULL.

Definition at line 205 of file PEAR.php.

Here is the caller graph for this function:

isError	(	$	data,
		$	code = null
	)

Tell whether a value is a PEAR error.

Parameters:

mixed	$data	the value to test
int	$code	if $data is an error object, return true only if $code is a string and $obj->getMessage() == $code or $code is an integer and $obj->getCode() == $code public

Returns:

bool true if parameter is an error

Definition at line 250 of file PEAR.php.

Here is the caller graph for this function:

loadExtension

(

$

ext

)

OS independant PHP extension load. Remember to take care on the correct extension name for case sensitive OSes.

Parameters:

string

$ext

The extension name

Returns:

bool Success or not on the dl() call

Definition at line 698 of file PEAR.php.

Here is the caller graph for this function:

PEAR

(

$

error_class = null

)

Constructor. Registers this object in $_PEAR_destructor_object_list for destructor emulation if a destructor object exists.

Parameters:

string

$error_class

(optional) which class to use for error objects, defaults to PEAR_Error. public

Returns:

void

Definition at line 149 of file PEAR.php.

Here is the caller graph for this function:

popErrorHandling

(

)

Pop the last error handler used

Returns:

bool Always true

See also:

PEAR::pushErrorHandling

Definition at line 677 of file PEAR.php.

Here is the call graph for this function:

popExpect

(

)

This method pops one element off the expected error codes stack.

Returns:

array the list of error codes that were popped

Definition at line 371 of file PEAR.php.

pushErrorHandling	(	$	mode,
		$	options = null
	)

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.

Parameters:

mixed	$mode	(same as setErrorHandling)
mixed	$options	(same as setErrorHandling)

Returns:

bool Always true

See also:

PEAR::setErrorHandling

Definition at line 649 of file PEAR.php.

Here is the call graph for this function:

& raiseError	(	$	message = null,
		$	code = null,
		$	mode = null,
		$	options = null,
		$	userinfo = null,
		$	error_class = null,
		$	skipmsg = false
	)

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.

Parameters:

mixed	$message	a text error message or a PEAR error object
int	$code	a numeric error code (it is up to your class to define these if you want to use codes)
int	$mode	One of PEAR_ERROR_RETURN, PEAR_ERROR_PRINT, PEAR_ERROR_TRIGGER, PEAR_ERROR_DIE, PEAR_ERROR_CALLBACK, PEAR_ERROR_EXCEPTION.
mixed	$options	If $mode is PEAR_ERROR_TRIGGER, this parameter specifies the PHP-internal error level (one of E_USER_NOTICE, E_USER_WARNING or E_USER_ERROR). If $mode is PEAR_ERROR_CALLBACK, this parameter specifies the callback function or method. In other error modes this parameter is ignored.
string	$userinfo	If you need to pass along for example debug information, this parameter is meant for that.
string	$error_class	The returned error object will be instantiated from this class, if specified.
bool	$skipmsg	If true, raiseError will only pass error codes, the error message parameter will be dropped.

public

Returns:

object a PEAR error object

PEAR::setErrorHandling

Since:

PHP 4.0.5

Definition at line 472 of file PEAR.php.

registerShutdownFunc	(	$	func,
		$	args = array()
	)

Use this function to register a shutdown method for static classes.

public

Parameters:

mixed	$func	The function name (or array of class/method) to call
mixed	$args	The arguments to pass to the function

Returns:

void

Definition at line 228 of file PEAR.php.

setErrorHandling	(	$	mode = null,
		$	options = null
	)

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.

Parameters:

int	$mode	One of PEAR_ERROR_RETURN, PEAR_ERROR_PRINT, PEAR_ERROR_TRIGGER, PEAR_ERROR_DIE, PEAR_ERROR_CALLBACK or PEAR_ERROR_EXCEPTION.
mixed	$options	When $mode is PEAR_ERROR_TRIGGER, this is the error level (one of E_USER_NOTICE, E_USER_WARNING or E_USER_ERROR).

When $mode is PEAR_ERROR_CALLBACK, this parameter is expected to be the callback function or method. A callback function is a string with the name of the function, a callback method is an array of two elements: the element at index 0 is the object, and the element at index 1 is the name of the method to call in the object.

When $mode is PEAR_ERROR_PRINT or PEAR_ERROR_DIE, this is a printf format string used when printing the error message.

public

Returns:

void

	)

Definition at line 566 of file PEAR.php.

& throwError	(	$	message = null,
		$	code = null,
		$	userinfo = null
	)

Simpler form of raiseError with fewer options. In most cases message, code and userinfo are enough.

Parameters:

mixed	$message	a text error message or a PEAR error object
int	$code	a numeric error code (it is up to your class to define these if you want to use codes)
string	$userinfo	If you need to pass along for example debug information, this parameter is meant for that.

Returns:

object a PEAR error object
