合并两个PHP数组 

1 <?php
2 $a1=array("a"=>"1","b"=>"2","c"=>"3");
3 $a2=array("d"=>"4","e"=>"5","c"=>"1");
4 $result=array_merge($a1,$a2);
5 print_r($result);
6 ?>

显示：

Array ( [a] => 1 [b] => 2 [c] => 1 [d] => 4 [e] => 5 )

例子：

1 <?php
2 $a1=array("a"=>"1","b"=>"2","c"=>"3",1);
3 $a2=array("d"=>"4","e"=>"5","c"=>"1",2);
4 $result=array_merge($a1,$a2);
5 print_r($result);
6 ?>

显示：

Array ( [a] => 1 [b] => 2 [c] => 1 [0] => 1 [d] => 4 [e] => 5 [1] => 2 )
