PHP simple two-table merge into the new table implementation process

In our daily development work, we have to deal with the database and data tables, we usually encounter multi-table query, table query, and two tables merge and then produce a new table and so on, today we will introduce a simple PHP simple two tables merged into a new table class, the 2 tables into 1 tables, and orderly arrangement of methods, involving the array of traversal and sequencing operation skills, has a certain practical value!

The first step is to first download the PHP simple two tables we need to use in this lesson to merge into the new Table class library: http://www.php.cn/xiazai/leiku/540

The second step, after the download, find the PHP class files we need, unzip to our local directory, create a new PHP file!

After the third step, we will call this class in the new PHP file, and instantiate the class:

<?phpinclude_once "biao.php";  Introduce class file  $phpig = new Union ();   Instantiate class  $lista = $phpig->lista = Array (3, 5, 8, one);  $listb = $phpig->listb = Array (2, 6, 8, 9, one, and up);  $LISTC = $phpig->listc;  $lena = $phpig->getlenght ($lista); Get table size  $lenb = $phpig->getlenght ($LISTB);  $i = $j = 0;  while ($i < $lena && $j < $lenb) {    $ea = $phpig->getelement ($lista, $i);    $eb = $phpig->getelement ($LISTB, $j);    if ($ea <= $eb) {      $LISTC = $phpig->listinsert ($LISTC, $ea);      + + $i;    } else {      $LISTC = $phpig->listinsert ($LISTC, $eb);      + + $j;    }  }  while ($i < $lena) {    $ea = $phpig->getelement ($lista, $i);    $LISTC = $phpig->listinsert ($LISTC, $ea);    + + $i;  }  while ($j < $lenb) {    $eb = $phpig->getelement ($LISTB, $j);    $LISTC = $phpig->listinsert ($LISTC, $eb);    + + $j;  }  Print_r ($LISTC);? >

Run the file and get the results as shown:
