Event bubbling is a type of DOM event propagation [1] where the event first triggers on the innermost target element, and then successively triggers on the ancestors (parents) of the target element in the same nesting hierarchy till it reaches the outermost DOM element or document object [2] (Provided the handler is initialized). It is one way ...
Code can be modularized into functions defined with keyword function. PHP supports an optional object oriented coding style, with classes denoted by the class keyword. Functions defined inside classes are sometimes called methods. Control structures include: if, while, do/while, for, foreach, and switch. Statements are terminated by a semicolon ...
PHP uses argc as a count of arguments and argv as an array containing the values of the arguments. [ 4 ] [ 5 ] To create an array from command-line arguments in the -foo:bar format, the following might be used:
PHP defines a large array of functions in the core language and many are also available in various extensions; these functions are well documented online PHP documentation. [224] However, the built-in library has a wide variety of naming conventions and associated inconsistencies, as described under history above.
In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also supported.
The arrays are heterogeneous: a single array can have keys of different types. PHP's associative arrays can be used to represent trees, lists, stacks, queues, and other common data structures not built into PHP. An associative array can be declared using the following syntax:
Bubbles, an oriole from the Angry Birds franchise; Bubbles, a yellow tang fish in the Finding Nemo franchise; Lourdes "Bubbles" Torres, in Philippine action drama series FPJ's Ang Probinsyano; Samantha "Bubbles" Montenegro, in Philippine action drama series FPJ's Batang Quiapo; Bubbles, in Jabberjaw; Bubbles, in The Adventures of Timmy the Tooth
Special array types are often defined by the language's standard libraries. Dynamic lists are also more common and easier to implement [dubious – discuss] than dynamic arrays. Array types are distinguished from record types mainly because they allow the element indices to be computed at run time, as in the Pascal assignment A[I,J] := A[N-I,2*J].
