inherited_from \Zend_Config

 Methods

Deep clone of this instance to ensure that nested Zend_Configs are also cloned.

__clone() : void
Inherited

Loads the section $section from the config file (or string $xml for access facilitated by nested object properties.

__construct(string $xml, mixed $section = null, array|boolean $options = false

Sections are defined in the XML as children of the root element.

In order to extend another section, a section defines the "extends" attribute having a value of the section name from which the extending section inherits values.

Note that the keys in $section will override any keys of the same name in the sections that have been included via "extends".

The $options parameter may be provided as either a boolean or an array. If provided as a boolean, this sets the $allowModifications option of Zend_Config. If provided as an array, there are two configuration directives that may be set. For example:

$options = array( 'allowModifications' => false, 'skipExtends' => false );

inherited_from \Zend_Config::__construct()

Parameters

$xml

string

XML file or string to process

$section

mixed

Section to process

$options

arrayboolean

Exceptions

\Zend_Config_Exception When xml is not set or cannot be loaded
\Zend_Config_Exception When section $sectionName cannot be found in $xml

Zend_Config provides a property based interface to an array. The data are read-only unless $allowModifications is set to true on construction.

__construct(array $array, boolean $allowModifications = false) : void
Inherited

Zend_Config also implements Countable and Iterator to facilitate easy access to the data.

Parameters

$array

array

$allowModifications

boolean

Magic function so that $obj->value will work.

__get(string $name) : mixed
Inherited

Parameters

$name

string

Returns

mixed

Support isset() overloading on PHP 5.1

__isset(string $name) : boolean
Inherited

Parameters

$name

string

Returns

boolean

Only allow setting of a property if $allowModifications was set to true on construction. Otherwise, throw an exception.

__set(string $name, mixed $value) : void
Inherited

Parameters

$name

string

$value

mixed

Exceptions

\Zend_Config_Exception

Support unset() overloading on PHP 5.1

__unset(string $name) : void
Inherited

Parameters

$name

string

Exceptions

\Zend_Config_Exception

Handle any errors from simplexml_load_file or parse_ini_file

_loadFileErrorHandler(integer $errno, string $errstr, string $errfile, integer $errline) 
Inherited

Parameters

$errno

integer

$errstr

string

$errfile

string

$errline

integer

Returns true if all sections were loaded

areAllSectionsLoaded() : boolean
Inherited

Returns

boolean

Defined by Countable interface

count() : integer
Inherited

Returns

integer

Defined by Iterator interface

current() : mixed
Inherited

Returns

mixed

Retrieve a value and return $default if there is no element set.

get(string $name, mixed $default = null) : mixed
Inherited

Parameters

$name

string

$default

mixed

Returns

mixed

Get the current extends

getExtends() : array
Inherited

Returns

array

Returns the section name(s) loaded.

getSectionName() : mixed
Inherited

Returns

mixed

Defined by Iterator interface

key() : mixed
Inherited

Returns

mixed

Merge another Zend_Config with this one. The items in $merge will override the same named items in the current config.

merge(\Zend_Config $merge) : \Zend_Config
Inherited

Parameters

$merge

\Zend_Config

Returns

\Zend_Config

Defined by Iterator interface

next() 
Inherited

Returns if this Zend_Config object is read only or not.

readOnly() : boolean
Inherited

Returns

boolean

Defined by Iterator interface

rewind() 
Inherited

Set an extend for Zend_Config_Writer

setExtend(string $extendingSection, string $extendedSection = null) : void
Inherited

Parameters

$extendingSection

string

$extendedSection

string

Prevent any more modifications being made to this instance. Useful after merge() has been used to merge multiple Zend_Config objects into one object which should then not be modified again.

setReadOnly() 
Inherited

Return an associative array of the stored data.

toArray() : array
Inherited

Returns

array

Defined by Iterator interface

valid() : boolean
Inherited

Returns

boolean

Merge two arrays recursively, overwriting keys of the same name in $firstArray with the value in $secondArray.

_arrayMergeRecursive(mixed $firstArray, mixed $secondArray) : array
Inherited

Parameters

$firstArray

mixed

First array

$secondArray

mixed

Second array to merge into first array

Returns

array

Throws an exception if $extendingSection may not extend $extendedSection, and tracks the section extension if it is valid.

_assertValidExtend(string $extendingSection, string $extendedSection) : void
Inherited

Parameters

$extendingSection

string

$extendedSection

string

Exceptions

\Zend_Config_Exception

Helper function to process each element in the section and handle the "extends" inheritance attribute.

_processExtends(\SimpleXMLElement $element, string $section, array $config = array()) : array

Parameters

$element

\SimpleXMLElement

XML Element to process

$section

string

Section to process

$config

array

Configuration which was parsed yet

Exceptions

\Zend_Config_Exception When $section cannot be found

Returns

array

Returns a string or an associative and possibly multidimensional array from a SimpleXMLElement.

_toArray(\SimpleXMLElement $xmlObject) : array | string

Parameters

$xmlObject

\SimpleXMLElement

Convert a SimpleXMLElement into an array

Returns

arraystring

 Properties

 

Whether in-memory modifications to configuration data are allowed

$_allowModifications : boolean

Default

 

Number of elements in configuration data

$_count : integer

Default

 

Contains array of configuration data

$_data : array

Default

 

This is used to track section inheritance. The keys are names of sections that extend other sections, and the values are the extended sections.

$_extends : array

Default

array()
 

Iteration index

$_index : integer

Default

 

Load file error string.

$_loadFileErrorStr : string

Default

null

Is null if there was no error while file loading

 

Contains which config file sections were loaded. This is null if all sections were loaded, a string name if one section is loaded and an array of string names if multiple sections were loaded.

$_loadedSection : mixed

Default

 

Whether to skip extends or not

$_skipExtends : boolean

Default

false
 

Used when unsetting values during iteration to ensure we do not skip the next element

$_skipNextIteration : boolean

Default

 Constants

 

XML namespace for ZF-related tags and attributes
