  2. PHP syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/PHP_syntax_and_semantics

    PHP has hundreds of base functions and thousands more from extensions. Prior to PHP version 5.3.0, functions are not first-class functions and can only be referenced by their name, whereas PHP 5.3.0 introduces closures. [35] User-defined functions can be created at any time and without being prototyped. [35]

  3. Comparison of programming languages (string functions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    In functional and list-based languages a string is represented as a list (of character codes), therefore all list-manipulation procedures could be considered string functions. However such languages may implement a subset of explicit string-specific functions as well.

    Visual Basic and Visual Basic .NET can also use the "+" sign but at the risk of ambiguity if a string representing a number and a number are together. Microsoft Excel allows both "&" and the function "=CONCATENATE(X,Y)". Rust has the concat! macro and the format! macro, of which the latter is the most prevalent throughout the documentation and ...

  5. Trimming (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Trimming_(computer...

    Many trim functions have an optional parameter to specify a list of characters to trim, instead of the default whitespace characters. For example, PHP and Python allow this optional parameter, while Pascal and Java do not. With Common Lisp's string-trim function, the parameter (called character-bag) is required.

  6. Naming convention (programming) - Wikipedia

    Perhaps the most well-known is Hungarian notation, which encodes either the purpose ("Apps Hungarian") or the type ("Systems Hungarian") of a variable in its name. [17] For example, the prefix "sz" for the variable szName indicates that the variable is a null-terminated string.

    Both character termination and length codes limit strings: For example, C character arrays that contain null (NUL) characters cannot be handled directly by C string library functions: Strings using a length code are limited to the maximum value of the length code. Both of these limitations can be overcome by clever programming.

  8. PHP - Wikipedia

    en.wikipedia.org/wiki/PHP

    In lieu of function pointers, functions in PHP can be referenced by a string containing their name. In this manner, normal PHP functions can be used, for example, as callbacks or within function tables. [225] User-defined functions may be created at any time without being prototyped.

  9. String operations - Wikipedia

    en.wikipedia.org/wiki/String_operations

    Simple single-letter substitution ciphers are examples of (ε-free) string homomorphisms. An example string homomorphism g uc can also be obtained by defining similar to the above substitution: g uc (‹a›) = ‹A›, ..., g uc (‹0›) = ε, but letting g uc be undefined on punctuation chars. Examples for inverse homomorphic images are
