PHP implements an improved version of dynamic histogram, php improved version of histogram
This article analyzes an example of PHP implementing an improved version of dynamic histogram. Share it with everyone for your reference. The specific analysis is as follows:
I have already written about the situation where only dynamic histograms are made. In fact, the principle is still very simple. Because there were new demands yesterday afternoon, I made some modifications this morning and divided the data according to different numbers and displayed it in the table.
Paste the code below so that you can check it later. The idea is just a temporary spark. I came up with it today. I may not be able to think of it next time, and I don’t have to think hard, so writing it down is a better form. .
<!DOCTYPE html>
<?php
// 计算上一个月的今天
function last_month_today($time)
{
$last_month_time = mktime(date("G", $time), date("i", $time), date("s", $time), date("n", $time), 0, date("Y", $time));
$last_month_t = date("t", $last_month_time);
if ($last_month_t < date("j", $time)) {
return date("Y-m-t H:i:s", $last_month_time);
}
return date(date("Y-m", $last_month_time) . "-d", $time);
}
?>
<?php
include dirname(dirname(dirname(__FILE__))) . '/config.php';
$endDate = date('Y-m-d');
$date = strtotime($endDate);
$beginDate = last_month_today($date);
$sql = 'select count(*) from newpro where p_date>\'' . $beginDate . '\' and p_date<\'' . $endDate . '\'';
$d = db()->query($sql)->fetch(PDO::FETCH_NUM);
$sql2 = $sql . ' and is_pa_check_first=1 and is_pa_check_second=1 and is_pa_check_third=1';
$d2 = db()->query($sql2)->fetch(PDO::FETCH_NUM);
$sql3 = $sql . ' and is_pa_check_first=1';
$d3 = db()->query($sql3)->fetch(PDO::FETCH_NUM);
$sql4 = $sql . ' and is_pa_check_first=1 and is_pa_check_second=1';
$d4 = db()->query($sql4)->fetch(PDO::FETCH_NUM);
// 查询每个人通过审核的情况：
$sqlab = 'select d_m,sum(sroce) as total_score,count(d_m) as total_number
from newpro
where is_pa_check_first=1
and is_pa_check_second=1
and is_pa_check_third =1
group by d_m';
$row = db()->query($sqlab)->fetchAll(PDO::FETCH_ASSOC);

<!-- 因为总的列数比较长，如果显示在一个表格中，数据会很拥挤，多的话根本就看不清楚。
所以需要将数据进行分割，根据长度进行动态的分割，显示在多张表中。
-->
<?php
$arr = array_chunk($row,2,false);//2表示分割的单位长度，false表示索引从0开始
foreach($arr as $newRow){
$thStr = "<th style='background-color:#669900' width='110px' height='30px'>产品开发编号</th>";
$trStr_total_score = "<tr align='center' style='background-color:silver' height='25px'><td>总分</td>";

$trStr_average_score = "<tr align='center' style='background-color:silver' height='25px'><td>平均分</td>";
$resultStr = "";
foreach ($newRow as $key => $value) {
// echo $key."=>".$value."<br/>";
$x = 0;
foreach ($value as $key2 => $value2) {
// echo $key2 . "=>" . $value2 . "<br/>";
if ($key2 == 'd_m') {
$thStr .= "<th style='background-color:#669900'>" . $value2 . "</th>"; // 表头
} elseif ($key2 == 'total_score') {
$value2 = sprintf("%.2f", $value2); //保留2位小数
$trStr_total_score .= "<td>" . $value2 . "</td>";
$x += $value2;
} elseif ($key2 == 'total_number') {
$trStr_total_number .= "<td>" . $value2 . "</td>";
$x /= $value2;
}
}
$x = sprintf("%.2f",$x);
$trStr_average_score .= "<td>" . $x . "</td>";
}
echo "<table border='0' width='100%'>";

echo $trStr_total_score . "</tr>";
echo $trStr_average_score . "</tr>";
echo "</table>";
echo "<p height='150px'></p>";
}
?>
</table>
</body>
</html>It is convenient not to create a database. In fact, it is very easy to build a test data table based on the query table name and field name. The key is the idea. No matter how it changes, the idea is the key.
In order to understand the effect of the code more conveniently, take a screenshot
I hope this article will be helpful to everyone’s PHP programming design.
