The target PHP file then accesses the data passed by the form through PHP's $_POST or $_GET variables, depending on the value of the method attribute used in the form. Here is a basic form handler PHP script that will display the contents of the first_name input field on the page: form.html
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:
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 ...
Arrays can contain mixed elements of any type, including resources, objects. [31] Multi-dimensional arrays are created by assigning arrays as array elements. PHP has no true array type. PHP arrays are natively sparse and associative. Indexed arrays are simply hashes using integers as keys. Indexed array:
For example, in the Pascal programming language, the declaration type MyTable = array [1.. 4, 1.. 2] of integer, defines a new array data type called MyTable. The declaration var A: MyTable then defines a variable A of that type, which is an aggregate of eight elements, each being an integer variable identified by two indices.
The PHP serialization format is the serialization format used by the PHP programming language. The format can serialize PHP's primitive and compound types, and also properly serializes references. [1] The format was first introduced in PHP 4. [2] In addition to PHP, the format is also used by some third-party applications that are often ...
Sample binary-state checkboxes, with some options disabled.

For example, the user may have to answer 'yes' (checked) or 'no' (not checked) on a simple yes/no question.
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string.
