[英]Picking up how many entries in a json array
I use the following code to extract information from a json page. 我使用以下代码从json页面提取信息。
$str = file_get_contents('http://fantasy.mlssoccer.com/web/api/elements/498/');
$jsonarray = json_decode($str, true);
$week1 = $jsonarray['fixture_history']['summary'][0][2];
$week2 = $jsonarray['fixture_history']['summary'][1][2];
Here's an excerpt of what it's taking from 这是摘录它的内容
{ "summary" :
[
[ 1, "PHI (A)", 14 ]
[ 2, "TOR (A)", 8 ]
]
}
At the moment only 2 weeks exist. 目前仅存在2周。 1 new entry will be added every week.
每周将添加1个新条目。 How do I code something to say "loop for however many weeks/entries exist"?
我如何编写代码来说“循环存在多少周/条目”?
Pretty much what I want to do is put this info into a HTML table and I want the code to know how many weeks are in there. 我想要做的就是将这些信息放入HTML表格中,我希望代码能够知道有多少周。 There will be 1 row of data for each week.
每周将有1行数据。
Let me know if this isn't clear.. and thanks! 如果不清楚,请告诉我..谢谢!
Use .length
使用
.length
In Javascript 在Javascript中

In PHP 在PHP中
echo count($jsonarray['fixture_history']['summary']);
