我需要用 csv 文件的值替换表 data.addData 。我怎样才能做到这一点？有人可以为我提供一个 foreach 或另一个循环来初始化表的值吗？
最佳答案
佩德，
尝试以下操作，因为 $lines[] 是一个数组
Caveat: the following suggested answer runs with couple of assumptions-- 1. You will always have 7 data points separated by comma 2. AND each data points will not be blank---if you want to, you could avoid this assumption by checking to see if its blank or not by using
isset()
table.addData([
<?php
$isFirst = TRUE;
foreach($lines as $line) {
$lineData = explode(",", $line);
echo ($isFirst === FALSE) ? "{'Date' : '$lineData[0]', 'Open' : '$lineData[1]', 'High' : '$lineData[2]', 'Low' : '$lineData[3]', 'Close' : '$lineData[4]', 'Adj Close' : '$lineData[5]', 'Volume' : '$lineData[6]'}," : "";
$isFirst = FALSE;
}
?>
希望这有帮助!
