Question

我们说我有一个这种格式的药物数据库：

-----------------------------------------------
| Medication Name |  Strength  |    Unit      |
-----------------------------------------------
| NORCO           |   5;325    |  mg/1;mg/1   |
| Amoxicillin     |     500    |     mg/1     |
| Augmentin       |  250;62.5  |mg/5mL; mg/5mL|
-----------------------------------------------

如何使用php以这种方式显示数据：

NORCO 5mg/325mg
Amoxicillin 500mg
Augmentin 250mg/5mL 62.5mg/5mL

使用/1可以轻松地从单位列中删除str_replace但是如何使用分号分隔单位来强调单位？

Answer 1

您可以使用php explode功能。可能还有其他更好的解决方案，对于初学者，您可以尝试下面的代码。

// Considering this is your data from database
$data = array(
            array(
                'name' => "NORCO",
                'strength' => "5;325",
                'unit' => "mg/1;mg/1"
            ),
            array(
                'name' => "Amoxicillin",
                'strength' => "500",
                'unit' => "mg/1"
            ),
            array(
                'name' => "Augmentin",
                'strength' => "250;62.5",
                'unit' => "mg/5mL; mg/5mL"
            ),
        );

// Looping through data
foreach ($data as $row) {
    $strength = explode(';', $row['strength']);
    $unit = explode(';', $row['unit']);
    $combine = combineStrengthUnit($strength, $unit);   
    echo $row['name'] . " " . $combine ;
    echo "<br/>";
}

// return combined Strength and Units
function combineStrengthUnit($strength, $unit)
{
    $combine_result = '';
    foreach ($strength as $key => $value) {
        $combine_result .= $value . trim(str_replace('/1', '', $unit[$key])) . " "; //trimming the spaces of unit
    }
    return $combine_result;
}

<强>输出：

NORCO 5mg 325mg
Amoxicillin 500mg
Augmentin 250mg/5mL 62.5mg/5mL

使用php将单位与优势结合起来
