what I want to say is:
ÔÚÊý×éµÄÔËËãÖÐthe result of (array1 = array2 + array3 )is different from (array1 =
array3 + array2).
for example:
<?php
$wang = array('1','2','3','5');
$zhang = array('11','2','5','8','9');
$added = $wang + $zhong;
print_r($added);
/*It will print
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 5 [4] => 9 )*/
//but the flllow is different
$added = $zhong + $wang;
print_r($added);
/*It will print
Array ( [0] => 11 [1] => 2 [2] => 5 [3] => 8 [4] => 9 )*/
?>
