Question

我想从php

中的数组输出一个特定的值

下面是我的代码，数组是$content

<?php
$content = $_POST;

for($i=1; $i < $content['itemCount'] + 1; $i++) {
  $name = 'item_name_'.$i;
  $quantity = 'item_quantity_'.$i;
  $price = 'item_price_'.$i;
  $image='item_image_'.$i;
  $option='item_options_'.$i;
  $total = $content[$quantity]*$content[$price];
}
?>

<?php
print_r( $content );

?>

输出显示如下：

Array ( [currency] => INR 
[shipping] => 0 
[tax] => 0 
[taxRate] => 0 
[itemCount] => 3 
[item_name_1] => Our Nest 
[item_quantity_1] => 1 
[item_price_1] => 1900 
[item_options_1] => image: CF01108.jpg, productcode: 602793420 
[item_name_2] => Our Nest 
[item_quantity_2] => 1 
[item_price_2] => 2100 
[item_options_2] => image: CF01110.jpg, productcode: 123870196 
[item_name_3] => Our Nest 
[item_quantity_3] => 1 
[item_price_3] => 1800 
[item_options_3] => image: CF01106.jpg, productcode: 416267436 )

如何在php变量中获取productcode值并回显它？

示例：

602793420,123870196,416267436

Answer 1

您可以使用productcode函数获取explode()，例如

$product_code = explode("productcode: ", $option)[1];

以下是参考资料：

explode()

所以你的代码应该是这样的：

<?php
    $content = $_POST;

    for($i=1; $i < $content['itemCount'] + 1; $i++) {
      $name = 'item_name_'.$i;
      $quantity = 'item_quantity_'.$i;
      $price = 'item_price_'.$i;
      $image='item_image_'.$i;
      $option='item_options_'.$i;
      $product_code = explode("productcode: ", $option)[1];
      $total = $content[$quantity]*$content[$price];
    }
?>

如果项目的选项将来会有更多的值，我宁愿建议这样做。
