1. In PHP, use preg_replace to replace sensitive characters in a string. One problem is that a specific segment of the string might not exist. Examples are as follows:
Plaintext
Order notes: Modified to: Yes search
Order notes: Modified to: 13123123, Order shipping notes: Modified to: 321312312
Order shipping notes: Modified to: 87987
Plaintext
Order notes:***Modified to:***
Order notes:***Modified to:***,Order shipping notes:***Modified to:***
Order shipping notes:***Modified to:***
2. The reason these 3 formats exist is that they are generated based on the following code:
PHP
$value = [];
if ($order['remarks'] != $latestOrder['remarks']) {
$value[] = sprintf(
'订单备注由%s变更为%s',
$order['remarks'],
$latestOrder['remarks']
);
}
if ($order['remarks_delivery'] != $latestOrder['remarks_delivery']) {
$value[] = sprintf(
'订单发货备注由%s变更为%s',
$order['remarks_delivery'],
$latestOrder['remarks_delivery']
);
}
if (!empty($value)) {
$data[OrderLogConstants::ORDER_REMARK] = implode(',', $value);
}
3. The final implemented code is as follows:
PHP
$originalDescription = $description;
$description = preg_replace('/(订单备注:)[\s\S]*修改为:[\s\S]*(,订单发货备注:)/', '$1***修改为:***,订单发货备注:', $description);
if ($originalDescription == $description) {
$description = preg_replace('/(订单备注:)[\s\S]*修改为:[\s\S]*/', '$1***修改为:***', $description);
}
$description = preg_replace('/(订单发货备注:)[\s\S]*修改为:[\s\S]*/', '$1***修改为:***', $description);
4. However, when there are more formats, such as over 10, hardcoding them in the program becomes unfeasible. I decided to abstract a method:
PHP
$value = [];
if (trim($order['customer_name']) != trim($latestOrder['customer_name'])) {
$value[] = sprintf(
'客户姓名由%s变更为%s',
$order['customer_name'],
$latestOrder['customer_name']
);
}
if ($order['customer_email'] != $latestOrder['customer_email']) {
$value[] = sprintf(
'联系邮箱由%s变更为%s',
$order['customer_email'],
$latestOrder['customer_email']
);
}
if ($order['customer_tel'] != $latestOrder['customer_tel']) {
$value[] = sprintf(
'联系电话由%s变更为%s',
$order['customer_tel'],
$latestOrder['customer_tel']
);
}
if ($order['customer_country_code'] != $latestOrder['customer_country_code']) {
$value[] = sprintf(
'所属国家由%s变更为%s',
$order['customer_country'],
$latestOrder['customer_country']
);
}
if ($order['customer_state'] != $latestOrder['customer_state']) {
$value[] = sprintf(
'省/州由%s变更为%s',
$order['customer_state'],
$latestOrder['customer_state']
);
}
if ($order['customer_city'] != $latestOrder['customer_city']) {
$value[] = sprintf(
'所属城市由%s变更为%s',
$order['customer_city'],
$latestOrder['customer_city']
);
}
if ($order['customer_zip'] != $latestOrder['customer_zip']) {
$value[] = sprintf(
'邮编由%s变更为%s',
$order['customer_zip'],
$latestOrder['customer_zip']
);
}
if (trim($order['customer_address1']) != trim($latestOrder['customer_address1'])) {
$value[] = sprintf(
'邮寄地址由%s变更为%s',
$order['customer_address1'],
$latestOrder['customer_address1']
);
}
if (trim($order['customer_address2']) != trim($latestOrder['customer_address2'])) {
$value[] = sprintf(
'备用地址由%s变更为%s',
$order['customer_address2'],
$latestOrder['customer_address2']
);
}
if ($order['customer_house_number'] != $latestOrder['customer_house_number']) {
$value[] = sprintf(
'门牌号由%s变更为%s',
$order['customer_house_number'],
$latestOrder['customer_house_number']
);
}
if (trim($order['customer_abnnumber']) != trim($latestOrder['customer_abnnumber'])) {
$value[] = sprintf(
'收件人税号由%s变更为%s',
$order['customer_abnnumber'],
$latestOrder['customer_abnnumber']
);
}
if (trim($order['customer_billing_address']) != trim($latestOrder['customer_billing_address'])) {
$value[] = sprintf(
'账单地址由%s变更为%s',
$order['customer_billing_address'],
$latestOrder['customer_billing_address']
);
}
if (!empty($value)) {
$data[OrderLogConstants::ORDER_CUSTOMER] = implode(',', $value);
}
PHP
$patterns = ['客户姓名:', '联系邮箱:', '联系电话:', '所属国家:', '省/州:', '所属城市:', '邮编:', '邮寄地址:', '备用地址:', '门牌号:', '收件人税号:', '账单地址:'];
$pattern = '修改为:';

}
}
return $description;
}
5. The format comparison before and after the final replacement is as follows, which meets expectations. See Figure 1:
