[英]How to split and sum comma separated multiple line values in php
I have one issue.我有一个问题。 How can i split and sum up multiple comma separated line values in php.如何在 php.ini 中拆分和总结多个逗号分隔的行值。 Following my mysql table screenshot按照我的mysql表截图
here my date wise miles filter page这里是我的日期明智里程过滤页面
I want to output miles colums like following when users enter from and to date.我想在用户输入日期和日期时输出英里列,如下所示。
IA 59.62
MD 7.88
IL 359.22
Total Miles : 426.72
How can i achieve this in php? Please help me.
my php code:我的 php 代码:
<?php
// Range.php
if(isset($_POST["From"], $_POST["to"]))
{
$conn = mysqli_connect("localhost", "root", "", "truckinvo");
$result = '';
$query = "SELECT * FROM tble_states_miles WHERE order_date BETWEEN '".$_POST["From"]."' AND '".$_POST["to"]."'";
$sql = mysqli_query($conn, $query);
?>
<table class="table table-bordered">
<tr>
Total Miles from the date between <?php echo $_POST["From"]; ?> to <?php echo $_POST["to"]; ?>
<th width="40%">Miles</th>
</tr>
<?php
if(mysqli_num_rows($sql) > 0)
{
while($row = mysqli_fetch_array($sql))
{
?>
<tr>
<td>
<?php
echo nl2br($row["miles"]); ?></td>
</tr>
<?php
}
}
else
{
?>
<tr>
<td colspan="5">No Data Found</td>
</tr>
<?php
}
?>
</table>
<?php echo $result; }
?>
I tried to use following code to split我尝试使用以下代码进行拆分
<?php
$f1 = preg_replace('/,\\s*/', "', '", $row["miles"]);
$f2 = preg_replace('/\\n/', "'), \n('", $f1);
?>
<?php echo $f2; ?>
Break per line, break each row to parts, display the name and sum up the values.每行拆分,将每一行拆分为多个部分,显示名称并汇总值。 Try:尝试:
Before the loop:循环前:
<?php $totalMiles = 0 ?>
Instead of:代替:
<td>
<?php
echo nl2br($row["miles"]); ?>
</td>
In the loop:在循环:
<td>
<?php
// iterate per state
foreach (explode("\n", $row['miles']) as $stateRow) {
// prepare the parts, we don't want any whitespace
$stateParts = array_filter(array_map('trim', explode(',', $stateRow)));
// the state's name (the first part)
$stateName = $stateParts[0];
// sum everything in the array
// this works, because the name will get cast to "0"
// try it: echo (int) 'IL';
$stateMiles = array_sum($stateParts);
// total mileage sum
$totalMiles += $stateMiles;
// display the result, any way you want
printf('%s miles %.2f', $stateName, $stateMiles);
}
?>
</td>
After the loop:循环后:
Total miles <?= $totalMiles ?>
