How to deal with PHP being unable to obtain data after the SSL certificate is installed on IIS
In recent years, with the increasing awareness of network security, the installation of SSL certificates has become increasingly important. In the Windows environment, many websites use IIS as the web server, and PHP is also widely used as the server-side scripting language. However, after installing the SSL certificate, sometimes there will be a problem that PHP cannot obtain data, which may cause website service abnormalities. This article provides a solution to this problem and provides detailed code examples.
Problem Analysis:
In a Windows environment, especially after installing an SSL certificate on the IIS server, PHP may have problems when requesting external HTTPS resources. This is because PHP does not support the SSL/TLS protocol by default, resulting in the inability to properly verify the SSL certificate. In this case, an error message like "cURL error 60: SSL certificate problem: unable to get local issuer certificate" usually appears.
Solution:
In order to solve the problem that PHP cannot obtain data after installing the SSL certificate on IIS, we can handle it through the following steps:
- Download the certificate File:
First, we need to download the root certificate file of the SSL certificate, which can be downloaded from the official website of the SSL Certificate Authority, and save it to the specified directory on the server.
- Configure the php.ini file:
Next, we need to configure the PHP php.ini file, enable the SSL extension and set the root certificate file path. Open the php.ini file, search for the following two lines of configuration, and make sure the configuration is correct:
extension=php_openssl.dll curl.cainfo = "C:/path/to/your/cacert.pem"
Among them, "C:/path/to/your/cacert.pem" is the path to the root certificate file.
- Use the cURL library for HTTPS requests:
In PHP, the cURL library is usually used for HTTP requests, including HTTPS requests. By modifying cURL's configuration, we can make it correctly validate SSL certificates when requesting HTTPS resources. The following is a simple sample code:
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://example.com/api'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true); curl_setopt($ch, CURLOPT_CAINFO, 'C:/path/to/your/cacert.pem'); $result = curl_exec($ch); curl_close($ch); echo $result;
In this code, we verify the SSL certificate by setting CURLOPT_SSL_VERIFYPEER, and CURLOPT_CAINFO specifies the path to the root certificate file.
- Test code:
Finally, we can test whether the modified code can successfully obtain HTTPS resources. This can be verified by visiting an HTTPS URL and getting the data.
Summary:
Through the above steps, we can solve the problem that PHP cannot obtain data after installing the SSL certificate on IIS. By configuring the php.ini file and using the cURL library, we can enable PHP to correctly verify the SSL certificate and successfully request HTTPS resources. In actual applications, please flexibly adjust the code according to the specific situation and ensure the validity of the SSL certificate.
I hope this article can help readers solve similar problems and ensure the security and normal operation of the website.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

This tutorial demonstrates how to efficiently process XML documents using PHP. XML (eXtensible Markup Language) is a versatile text-based markup language designed for both human readability and machine parsing. It's commonly used for data storage an

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

Use most text editors to open XML files; if you need a more intuitive tree display, you can use an XML editor, such as Oxygen XML Editor or XMLSpy; if you process XML data in a program, you need to use a programming language (such as Python) and XML libraries (such as xml.etree.ElementTree) to parse.

In PHP, you can effectively prevent CSRF attacks by using unpredictable tokens. Specific methods include: 1. Generate and embed CSRF tokens in the form; 2. Verify the validity of the token when processing the request.
