forach

Forach is not a formal term in programming or computer science. It is a common misspelling of foreach, the looping construct used in several languages to iterate over elements of a collection. Because foreach exists in both keyword-based forms (such as PHP) and method-based forms (such as JavaScript’s forEach), a misspelled variant can appear in code, documentation, or informal discussions.

The misspelling typically arises from typographical errors or keyboard layout mistakes that exchange or omit letters. Since foreach contains the sequence “each,” dropping the e yields forach, and adding case variations can yield further confusions. Some editors and linters may flag forach as a syntax error, while others may ignore it if it appears in non-code contexts or as a variable name by accident.

In practice, forach should be corrected to foreach or to the language-specific form appropriate to the context. In PHP, the correct syntax is foreach ($array as $value) { ... }. In JavaScript, the standard is array.forEach(function (value) { ... }) or with arrow functions. Although forach is not a defined construct, understanding its non-existence helps maintain code clarity and reduces debugging time.
