Classic example of Windows XP hardware optimized PHP code optimization

I used the method of distinguishing blocks by key, then assigning the block to other variables, and then doing some work, so I used a lot of for and foreach, and the code was very large, so I was back.
After the above guidance, found really good simple, and now share with you.
Id
FIELD1
FIELD2 FIELD3 FIELD4 Key
1
*** *** *** *** Meat1
2
*** *** *** *** Meat1
3
*** *** *** *** Meat1
4 *** *** *** *** Meat1
5
*** *** *** *** Fruit2
6 *** *** *** *** Fruit2
7
*** *** *** *** Fruit2
8
*** *** *** *** Fruit2
9
*** *** *** *** Fruit2
10
*** *** *** *** Food3
11
*** *** *** *** Food3

Now the result is as shown above

Requirement: To operate on an array that has been sorted by key, the item of the same key is processed.

Hint: This is a very typical parent-child table structure, that is to say, it is a combination of two tables, can be processed into two arrays, convenient array in the face of the operation of the block
array1:id| Key

Id
Key
1
Meat1
2
Meat1
3
Meat1
4 Meat1
5
Fruit2
6 Fruit2
7
Fruit2
8
Fruit2
9
Fruit2
10
Food3
11
Food3

Array2:key = Array (id,field1,field2,field3,field4,field5,key)


Id
FIELD1
FIELD2 FIELD3 FIELD4 Key
Meat1=>
1
*** *** *** *** Meat1
2
*** *** *** *** Meat1
3
*** *** *** *** Meat1
4 *** *** *** *** Meat1
Fruit2=> 5
*** *** *** *** Fruit2
6 *** *** *** *** Fruit2
7
*** *** *** *** Fruit2
8
*** *** *** *** Fruit2
9
*** *** *** *** Fruit2
Food3=> 10
*** *** *** *** Food3
11
*** *** *** *** Food3

Implementing an array separation code like above

After that, it is very convenient to access the block data of the Temparray.

foreach ($tempArray as $row) {

array1[$row [' ID ']] = $row [' Key '];

array2[$row [' Key ']][] = $row;

}

Accessing and handling code

foreach ($array 1 as $ID = = $Key) {

$this->dosomething ($ID);

Access Temparray block array $array2[$Key]

$this->dosomething2 ($array 2[$Key]);

}

The above is a classic example of Windows XP hardware optimized PHP code optimization, including the Windows XP hardware optimization aspects, I hope to be interested in PHP tutorial friends helpful.
