php - Like 语句匹配字符串的一部分

Question

我正在使用脚本从 CSV 更新 Magento 中的产品价格。

目前，CSV 中的 SKU 与 Magento 中的 SKU 不完全匹配。例如，CSV 中的一个可能是 33456，但在 Magento 中它将是 003456_01 或 003456_02。所以我需要脚本只匹配 SKU 的中间部分，所以如果在 Magento 中的 SKU 之后有 00 或 _01 它仍然会更新所有匹配该 SKU 的内容在移动到下一行之前。

$mageFilename = 'app/Mage.php';
    require_once $mageFilename;
    Mage::setIsDeveloperMode(true);
    ini_set('display_errors', 1);
    umask(0);
    Mage::app('admin');
    Mage::register('isSecureArea', 1);
    Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

    set_time_limit(0);
    ini_set('memory_limit','1024M');

如果只想匹配中间部分，使用%

$sql = "SELECT sku FROM table WHERE item LIKE '%$code%'";
