sum is a legacy utility available on some Unix and Unix-like operating systems. This utility outputs a 16-bit checksum of each argument file, as well as the number of blocks they take on disk. [1] Two different checksum algorithms are in use. POSIX abandoned sum in favor of cksum.
MUMPS allows multiple commands to appear on a line, grouped into procedures (subroutines) in a fashion similar to most structured programming systems. Storing variables in the database (and on other machines on the network) is designed to be simple, requiring no libraries and using the same commands and operators used for working with variables ...
Historically, the development of PHP has been somewhat haphazard. To counter this, the PHP Framework Interop Group (FIG) has created The PHP Standards Recommendation (PSR) documents that have helped bring more standardization to the language since 2009. [1]

MEAN (MongoDB, Express.js, AngularJS (or Angular), and Node.js) [1] is a source-available JavaScript software stack for building dynamic web sites and web applications. [2] A variation known as MERN replaces Angular with React.js front-end, [3] [4] and another named MEVN use Vue.js as front-end.
[1] Each letter in the acronym stands for one of its four open-source building blocks: Linux for the operating system; Apache HTTP Server; MySQL for the relational database management system; Perl, PHP, or Python for the programming language; The components of the LAMP stack are present in the software repositories of most Linux distributions.
MongoDB can be used as a file system, called GridFS, with load-balancing and data-replication features over multiple machines for storing files. This function, called a grid file system, [36] is included with MongoDB drivers. MongoDB exposes functions for file manipulation and content to developers.
Since PHP 4.0.1 create_function(), a thin wrapper around eval(), allowed normal PHP functions to be created during program execution; it was deprecated in PHP 7.2 and removed in PHP 8.0 [226] in favor of syntax for anonymous functions or "closures" [227] that can capture variables from the surrounding scope, which was added in PHP 5.3.
