after the variable name, such as:
$people =array (' name ', ' Sex ', ' nation ', ' birth ');
Echo $people [2];
?>
The output of $people[2] is displayed as nation (the first item in the index is counted from 0).
In addition to supporting numeric index arrays, PHP supports related arrays. The so-called correlation array, is the customizable keyword to replace the non-intuitive digital index, such as:
$peoples =array (' xm ' = ' name ', ' xb ' = ' sex ', ' m
Digital Index, for example:
$ Doneles = array ('xm '=> 'name', 'xb' => 'sex', 'mz' => 'nation ', 'CS '=> 'birth ');
Echo $ doneles ['CS '];
?>
The related array is used to make the output selection intuitive (no pre-calculation of index numbers is required and then output). the defined keywords and values are defined using the "=>" symbol.
Based on the two display methods of php array elements, you can also create numbers automatic

In most cases, the information is returned through the PSFI buffer, but there are some cases that can be effectively included in the DWORD return of the function. The return value of the shgetfileinfo () functionReturns A value whose meaning depends on the uflags parameter.

registration during census, such as name, gender, ethnicity, and birth, can be used as an array.
PHP creates an array and uses the array () structure to define it. for example:
$ People = array ('name', '***', 'nation', 'brith ');
How to display the values of each element in the array is the index starting from 0. The index number is in square brackets after the variable name. for example:
$ People = array ('name', '***', 'nation', 'birth ');Echo $ people [2];?>
The output $ people [2] indica

What is an array? An array is a programming structure that is a variable that stores a set or series of values.
For example, when the census of personal identity registration, such as name, gender, ethnicity, birth, etc. can be used as an array.
The creation of arrays in the PHP tutorial is defined using the array () structure, such as:
$people =array (' name ', ' Sex ', ' nation ', ' brith ');
