Launched in 2001, ionCube PHP Accelerator (PHPA) was the first freely available PHP accelerator to compete with the commercial Zend Cache product. Created before ionCube Ltd. was founded and at a time when the performance of PHP was regarded as lackluster when compared to other popular web programming languages, [citation needed] PHPA showed that PHP can compete with other languages ...
By way of illustration, the following code fragments demonstrate detection of patterns within event streams. The first is an example of processing a data stream using a continuous SQL query (a query that executes forever processing arriving data based on timestamps and window duration).
As of 21 January 2025 (two months after PHP 8.4's release), PHP is used as the server-side programming language on 75.0% of websites where the language could be determined; PHP 7 is the most used version of the language with 47.1% of websites using PHP being on that version, while 40.6% use PHP 8, 12.2% use PHP 5 and 0.1% use PHP 4.
The InputStreamReader class converts an InputStream to a Reader and the OutputStreamWriter class converts an OutputStream to a Writer. Both these classes have constructors that support specifying the character encoding to use. If no encoding is specified, the program uses the default encoding for the platform.
an input stream that wraps a file stream buffer. Provides functions to open or close a file in addition to those of generic input stream ifstream – operates on characters of type char; wifstream – operates on characters of type wchar_t; basic_istringstream: an input stream that wraps a string stream buffer.
The C programming language provides many standard library functions for file input and output.These functions make up the bulk of the C standard library header <stdio.h>. [1] The functionality descends from a "portable I/O package" written by Mike Lesk at Bell Labs in the early 1970s, [2] and officially became part of the Unix operating system in Version 7.
The writer receives a pipe from the shell for its output to be sent to the reader's input stream. [67] The command-line syntax is alpha | bravo. alpha will write to the pipe when its computation is ready and then sleep in the wait queue. [68] bravo will then be moved to the ready queue and soon will read from its input stream. [69]
Compression algorithms often code in bitstreams, as the 8 bits offered by a byte (the smallest addressable unit of memory) may be wasteful. Although typically implemented in low-level languages , some high-level languages such as Python [ 1 ] and Java [ 2 ] offer native interfaces for bitstream I/O.
