Understand the meaning of class first. Class should be understood as a type, like Int,char, as a user-defined type. Use this type to declare a variable, such as int x, MyClass my, and so on. This is like the variable x has an int type, and the variable my has the MyClass type. If you understand this, it's good to explain this, and this is the pointer to my. If there is another variable MyClass mz,mz This is
... Z...A...Z)
The Sort () function also has a second argument that shows whether ascending rules are used to compare numbers or strings. Like what:
echo "---sorted by number in ascending order---$num 2=array (' 26 ', ' 3 ',);
Sort ($num 2,sort_numeric);
foreach ($num 2 as $mychrs)
echo $mychrs. " ";
echo "$num 3=array (' 26 ', ' 3 ');
Sort ($num 3,sort_string);
foreach ($num 3 as $mychrs)
echo $mychrs. " ";
?>
Sort_numeric and sort_string are used to declare ascending order by number or ch
, such as:
Copy Code code as follows:
$num 1=range (1,9);
Rsort ($num 1);
This is actually equivalent to range (9,1)
Ordering of associative arrays in 3,phpIn addition to supporting numeric indexed arrays, PHP supports related arrays. For example, the following array is a related (associative) array:
Copy Code code as follows:
$peoples =array (' xm ' => ' name ', ' xb ' => ' sex ', ' mz ' => ' nation ', ' cs '
Today I'll make a summary of this knowledge point.
1. What is this
To understand the meaning of class first, class should be understood as a type, like Int,char, which is a user-defined type. (although build-in types are much more complex than int char, the first thing to understand
They are the same type). This type can be used to declare a variable, such as int x, MyClass my, and so on. This way, as variable x has an int type, the variable my has a MyClass type. Understand this

Step One: Open the binding program in UltraEdit hexadecimal, select the contents of the second MZ to the third MZ (that is, the second file), and copy the part. Then create a new file, paste it, and save it as an EXE file.
Step Two: Select the third MZ to the end of the file (that is, the third file), the same copy, new file paste, save as EXE file.
Step three:

Rommon 6 > Boot bootdisk: C7600rsp72043-ipservices-mz.151-3.s4.bin But the result of the guidance is
square brackets after the variable name, for example:
$people =array (' name ', ' Sex ', ' nation ', ' birth ');
Echo $people [2];
?>
The $people[2 of the output] is the display of nation (the first item of the index counts from 0).
In addition to supporting numeric indexed arrays, PHP supports related arrays. An associated array is a customizable keyword that replaces an intuitive digital index, such as:
$peoples =array (' xm ' => ' name ', ' xb ' => ' sex ', '

, gender, ethnicity, and birth, can be used as an array.
The array created in PHP is defined using the array () structure, for example:
$ People = array ('name', 'sex', 'nation', 'brith ');
To display the values of each element in an array, we use an index starting from 0. The index number is in square brackets after the variable name. for example:
$ People = array ('name', 'sex', 'nation', 'birth ');
Echo $ people [2];
?>
The output $ people [2] indicates that nation is displayed (the first in
