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]
The elseif statement, in the Ada language for example, is simply syntactic sugar for else followed by if. In Ada, the difference is that only one end if is needed, if one uses elseif instead of else followed by if. PHP uses the elseif keyword [1] both for its curly brackets or colon syntaxes.
^m int in PHP has the same width as long type in C has on that system. ^n Erlang is dynamically typed. The type identifiers are usually used to specify types of record fields and the argument and return types of functions. [5] ^o When it exceeds one word. [6]
IF..THEN..(ENDIF). Rather than being restricted to a jump, any simple statement, or nested block, could follow the THEN key keyword. This a structured form. IF..THEN..ELSE..(ENDIF). As above, but with a second action to be performed if the condition is false. This is one of the most common forms, with many variations.
The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...

Snostorm (Snostorm3) is a version of the SNOBOL4 language with structured programming constructs added. It compensates for the near absence of structured programming constructs in SNOBOL4 by providing IF, ELSEIF, ELSE, LOOP, CASE, and PROCEDURE statements, among others.
<![if expression]> ... <![endif]> The code between the if and endif markup can be any HTML content that is included if the condition evaluates true or excluded otherwise. An expression can contain the name of a feature, literal values and comparison operators. Feature names include: IE – version of IE that is parsing the HTML document
