Dealing with Arguments Passed by Reference

The object on the server is replace with the object passed.

Return a string describing the last error that occured on the passed XSLT processor.

Return an error code describing the last error that occured on the passed XSLT processor.

As of PHP 4.0.6 the rownumber cannot be passed as a constant, but rather as a variable.

Returns an identifier to be passed to the other DBM functions on success, or FALSE on failure.

Returns an associative array containing information about a user referenced by an alphanumeric username, passed in the username parameter.

If your function accepts arguments passed by reference that you intend to modify, you need to take some precautions.

Returns an associative array containing information about a user referenced by a numeric user ID, passed in the uid parameter.

Allows you to mark certain parameters so that they're forced to be passed by reference. You usually should set this to NULL.

Adds a root element node to a dom document and returns the new node. The element name is given in the passed parameter.

But this is not the case with regular parameters! All other parameters that are not passed by reference are in a read only state.

ע The maximum number passed to the backlog parameter highly depends on the underlying platform. On linux, it is silently truncated to SOMAXCONN. On win32, if passed SOMAXCONN, the underlying service provider responsible for the socket will set the backlog to a maximum reasonable value. There is no standard provision to find out the actual backlog value on this platform.

因为他在一家服装店花了一张抢劫赃款 Because he passed a stolen bill in a dress shop.

你所有午餐时间这样度过吗 跟这个那个姑娘 Is this how all your lunch hours are passed, with some girl or other?

Before a new sibling is added it is first duplicated. Therefore the new child is a completely new copy which can be modified without changing the node which was passed to this function. If the node passed has children itself, they will be duplicated as well, which makes it quite easy to duplicate large parts of a xml document. The return value is the added sibling. If you plan to do further modifications on the added sibling you must use the returned node.

The config.m4 file is responsible for parsing the command line options passed to configure at configuration time. This means that it has to check for required external files and do similar configuration and setup tasks.

If a fourth string argument is passed, this string is inserted at the end of the header. This is typically used to add extra headers. Multiple extra headers are separated with a carriage return and newline.

Parses str as if it were the query string passed via an URL and sets variables in the current scope. If the second parameter arr is present, variables are stored in this variable as an array elements instead.

The optional third and fourth arguments to this function, authns and addtl are passed by reference and, if given, will be populated with Resource Records for the Authoritative Name Servers, and any Additional Records respectively. See the example below.

Returns the numeric position of the last occurrence of needle in the haystack string. Note that the needle in this case can only be a single character. If a string is passed as the needle, then only the first character of that string will be used.

ע Due a limitation in the current Zend Engine it is not possible to pass a constant modifier like NULL directly as a parameter to a function which expects this parameter to be passed by reference. Instead use a temporary variable or an expression with the leftmost member being a temporary variable

In the tradition of PHP, arrays and hashtables may pretty much be used interchangably. Note that hashtables in PHP may only be indexed by integers or strings and that arrays of primitive types in Java can not be sparse. Also note that these constructs are passed by value, so may be expensive in terms of memory and time.

What we didn't say yet is that under the circumstances presented so far, you don't have write access to any zval containers designating function parameters that have been passed to you. Of course, you can change any zval containers that you created within your function, but you mustn't change any zvals that refer to Zend internal data!
