The PHP serialization format is the serialization format used by the PHP programming language. The format can serialize PHP's primitive and compound types, and also properly serializes references. [1] The format was first introduced in PHP 4. [2] In addition to PHP, the format is also used by some third-party applications that are often ...
Rather than using the ZIP file format the simpler tar format was used, and the first PHAR was created using the tar command line utility [1] as a proof of concept. On June 14, 2004 [ 2 ] the initial PHP_Archive package was proposed to PEAR and on December 13, 2004 it was accepted unanimously.
A GROUP BY statement in SQL specifies that a SQL SELECT statement partitions result rows into groups, based on their values in one or several columns. Typically, grouping is used to apply some sort of aggregate function for each group. [1] [2] The result of a query using a GROUP BY statement contains one row for
The WebKit and Blink layout engines, used for example in the Safari and Chrome web browsers respectively, uses the libxslt library to do XSL transformations. [30] Bindings exist for Python, [31] Perl, [32] Ruby, [33] PHP, [34] Common Lisp, [35] Tcl, [36] and C++. [37] Microsoft provides two XSLT processors (both XSLT 1.0 only).
PHP supports an optional object oriented coding style, with classes denoted by the class keyword. Functions defined inside classes are sometimes called methods. Control structures include: if, while, do/while, for, foreach, and switch. Statements are terminated by a semicolon, not line endings. [5]
For example, the overall sum of a roll-up is just the sum of the sub-sums in each cell. Functions that can be decomposed in this way are called decomposable aggregation functions, and include COUNT, MAX, MIN, and SUM, which can be computed for each cell and then directly aggregated; these are known as self-decomposable aggregation functions. [13]
The foreach statement in some languages has some defined order, processing each item in the collection from the first to the last. The foreach statement in many other languages, especially array programming languages, does not have any particular order.
In the above example, the application might supply the values "bike" for the first parameter and "10900" for the second parameter, and then later the values "shoes" and "7400". The alternative to a prepared statement is calling SQL directly from the application source code in a way that combines code and data.
