Question

这里是我的代码。它工作和运行，并做我想做的一切，但它太长了。我怎么能压缩它？我的PHP级别是基本的。

我会使用数组吗？还是一个功能？您能否发布用于提高效率的代码？

<?php
$product = $result[CategoryId];

if ($product == "1") {
    echo "Tonneau Cover to suit";
} elseif ($product == "2") {
    echo "Clip On Tonneau Cover to suit";
} elseif ($product == "3") {
    echo "INSERT";
} elseif ($product == "4") {
    echo "INSERT";
} elseif ($product == "5") {
    echo "INSERT";
} elseif ($product == "6") {
    echo "INSERT";
} elseif ($product == "7") {
    echo "INSERT";
} elseif ($product == "8") {
    echo "INSERT";
} elseif ($product == "9") {
    echo "INSERT";
} elseif ($product == "10") {
    echo "INSERT";
} elseif ($product == "11") {
    echo "INSERT";
} elseif ($product == "12") {
    echo "INSERT";
} elseif ($product == "13") {
    echo "INSERT";
} elseif ($product == "14") {
    echo "INSERT";
} elseif ($product == "15") {
    echo "INSERT";
} elseif ($product == "16") {
    echo "INSERT";
} elseif ($product == "17") {
    echo "INSERT";
} else {
    echo ".";
}
?>

Answer 1

是的，您可以这种方式使用数组

$product = $result[CategoryId];
$ogh=["Tonneau Cover to suit","Clip On Tonneau Cover to suit","INSERT"];
if(count($ogh)>$product)
  echo $ogh[$product];
else
    echo "Invalid";

根据示例中的内容：

<?php
$product = (int) $result['CategoryId'];

if ($product === 1) {
    echo "Tonneau Cover to suit";
} elseif ($product === 2) {
    echo "Clip On Tonneau Cover to suit";
} elseif ($product >=3 || $product <=17) {
    echo "INSERT";
} else {
    echo ".";
}
?>
