php array_push()数组函数:将一个或多个单元压入数组的末尾（入栈）

"; 
$arr11=array('成绩1'=>65,'成绩2'=>25,'成绩3'=>87,'成绩4'=>85,'成绩5'=>45,'成绩6'=>66); 
$arr22=array(a,b,c,d,e); 
echo "数组arr11的信息："; 
echo "
"; 
print_r($arr11); 
echo "
"; 
echo "数组arr22的信息："; 
echo "
"; 
print_r($arr22); 
echo "
"; 
echo "数组arr1原来的元素的个数为：".count($arr11)."
"; 
$num1=array_push($arr11,12,55,66,100); 
echo "入栈后，数组的总的元素个数为：".$num1."!此时数组的元素分别为:
"; 
echo "
"; 
print_r($arr11); 
echo "
"; 
$num2=array_push($arr11,$arr22); 
echo "数组arr22入栈到数组arr11后:"; 
echo "入栈后，数组的总的元素个数为：".$num2."!此时数组的元素分别为:
"; 
echo "
"; 
print_r($arr11); 
echo "
"; 
?>

运行结果如下：
