复制代码 代码如下:

/*函数array_push():将一个或多个单元压入数组的末尾(入栈)
* 1、语法:int array_push ( array &array, mixed var [, mixed ...] )
* 2、描述:将 array 当成一个栈,并将传入的变量压入 array 的末尾。array 的长度将根据入栈变量的数目增加。
* 3、注意事项:
* 3.1、该函数返回数组新的元素的总数
* 3.2、如var为数组,则该数组是作为一个数组变量入栈到数组栈中,即原数组中的长度是增加一个单元

echo "***********************************************************************
";
$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);
$arr22=array(a,b,c,d,e);
echo "数组arr11的信息:";
echo "
"; <br>print_r($arr11); <br>echo "
Copy after login
Copy after login
Copy after login
";
echo "数组arr22的信息:";
echo "
"; <br>print_r($arr22); <br>echo "
Copy after login
";
echo "数组arr1原来的元素的个数为:".count($arr11)."
";
$num1=array_push($arr11,12,55,66,100);
echo "入栈后,数组的总的元素个数为:".$num1."!此时数组的元素分别为:
";
echo "
"; <br>print_r($arr11); <br>echo "
Copy after login
Copy after login
Copy after login
";
$num2=array_push($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 "
"; <br>print_r($arr11); <br>echo "
Copy after login
Copy after login
Copy after login
";
?>

运行结果如下:
