Language construct
Appearance
A language construct is a syntactically allowable part of a program that may be formed from one or more lexical tokens in accordance with the rules of a programming language.
The term Language Constructs is often used as a synonym for control structure, and should not be confused with a function.
Examples of language constructs
In PHP, for example, print is not actually a real function (it is a language construct in php).According to [[1]]
<?
print 'Hello world';
?>
Is the same as:
<?
print('Hello world');
?>
