Cross-origin request refers to the situation where the content running on a web page interacts with resources from a different domain. To address the PHP cross-origin request issue, several methods can be adopted:<\/p>\n

    \n
  1. Utilizing CORS (Cross-Origin Resource Sharing): Setting response headers in PHP code to allow requests from specific sources. Cross-origin requests can be achieved by setting response headers such as Access-Control-Allow-Origin, Access-Control-Allow-Headers, and Access-Control-Allow-Methods.<\/li>\n<\/ol>\n
    header<\/span>('Access-Control-Allow-Origin: *'<\/span>);\r\nheader<\/span>('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS'<\/span>);\r\nheader<\/span>('Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept'<\/span>);\r\n<\/code><\/pre>\n
      \n
    1. Utilize JSONP (JSON with Padding): JSONP is a method of fetching data across domains using the script tag. In PHP, you can return data in JSONP format, and the frontend can retrieve the data by dynamically creating a script tag.<\/li>\n<\/ol>\n
      $callback<\/span> = $_GET<\/span>['callback'<\/span>];\r\n$data<\/span> = array<\/span>('message'<\/span> => 'Hello, World!'<\/span>);\r\necho<\/span> $callback<\/span> . '('<\/span> . json_encode<\/span>($data<\/span>) . ')'<\/span>;\r\n<\/code><\/pre>\n
        \n
      1. Utilizing a proxy server: Send the cross-origin request to the proxy server, which forwards the request and returns the data. This allows bypassing the browser’s same-origin policy and achieving cross-origin requests.<\/li>\n<\/ol>\n
        The above are several common methods to solve the issue of PHP cross-origin requests. Choose the appropriate method based on the specific situation.<\/p>\n","protected":false},"excerpt":{"rendered":"
