libxml_get_errors

Function name: libxml_get_errors()

Applicable version: PHP 5, PHP 7

Function Description: The libxml_get_errors() function gets all XML errors in the current document and returns these errors as an array.

Syntax: libxml_get_errors(): array

Return value: Returns an array containing XML errors, or returns an empty array if no errors occur.

Example:

 <?php // 创建一个包含错误的XML 文档$xml = "<root><element1>value1</element1><element2>value2</element2>"; // 禁用错误报告libxml_use_internal_errors(true); // 使用SimpleXML 解析XML 文档$sxe = simplexml_load_string($xml); // 获取所有的XML 错误$errors = libxml_get_errors(); // 遍历错误数组并输出每个错误的消息foreach ($errors as $error) { echo "错误级别: " . $error->level . "<br>"; echo "错误消息: " . $error->message . "<br>"; echo "错误行号: " . $error->line . "<br>"; echo "错误列号: " . $error->column . "<br><br>"; } // 清除错误缓冲区libxml_clear_errors(); ?>

In the above example, we first created an XML document containing the error. Then, we use the libxml_use_internal_errors() function to disable error reporting so that we can get error information instead of throwing the exception directly. Next, we parse the XML document using the simplexml_load_string() function and use the libxml_get_errors() function to get all XML errors. Finally, we iterate through the error array and output the level, message, line number, and column number for each error.

Note that after using the libxml_get_errors() function, you should use the libxml_clear_errors() function to clear the error buffer so that the previous error will not be returned the next time you use the function.
