PHP - 附加元素的数组 [英] PHP - Append elements to array

问题描述

我有用于呈现使用PHPGraphLib的曲线图的阵列。我可以使这项工作很好，但只能用硬codeD值。

我得到可能的语法错误从Netbeans的警告。

什么是附加元素这种类型的数组的正确方法？

  //创建新的图形对象，并添加图形数据
$图=新PHPGraphLib（650400）;
$数据=阵列（00:00=＆GT; -9，
                        00:15=＆GT; -8，
                        00:30=＆GT; -3.5，
                        0点45分=＆GT; 5，
                        01:00=＆GT; 11，
                        01:15=＆GT; 12.5，
                        01:30=＆GT; 10.5，
                        01:45=＆GT; 11，
                        02:00=＆GT; 2，
                        02:15=＆GT; -2，
                        02:30=＆GT; 2，
                        02:45=＆GT; -2，
                        03:00=＆GT; 14）;array_push（$的数据，03:15=＆GT; 16）; //这是我不能获得工作的一部分//绘图数据
$ graph-＆GT; addData（$的数据）;
 

解决方案

到一个新的元素添加到一个关联数组的语法是：

  $数据[03:15] = 16;
 

array_push 用于与价值观，不相关联的元素。它通常只与具有数字指标，而不是关联数组，因为它通过在阵列中加入1到最高的数字索引生成密钥的阵列中。

I have an array that is used to render a graph using PHPGraphLib. I can make this work fine, but only with hard coded values.

I get "POSSIBLE syntax error" warning from Netbeans.

What is the correct way of appending elements to this type of array?

//Create new graph object and add graph data
$graph = new PHPGraphLib(650,400);
$data = array           ("00:00" => -9,
                        "00:15" => -8,
                        "00:30" => -3.5,
                        "00:45" => 5, 
                        "01:00" => 11,
                        "01:15" => 12.5,
                        "01:30" => 10.5,
                        "01:45" => 11,
                        "02:00" => 2,
                        "02:15" => -2,
                        "02:30" => 2,
                        "02:45" => -2,
                        "03:00" => 14);

array_push($data, "03:15" => 16);  //This is the part I cannot get to work

//Plot data
$graph->addData($data);

解决方案

The syntax to add a new element to an associative array is:

$data["03:15"] = 16;

array_push is used with values, not associative elements. It's normally used only with arrays that have numeric indexes, not associative arrays, as it generates the key by adding 1 to the highest numeric index in the array.
