Error: pathinfo() expects parameter 1 to be string, object given

This error indicates that the pathinfo() function in PHP is expecting a string as its first parameter, but it received an object instead. The pathinfo() function is used to retrieve information about a file path, such as the directory name, filename, extension, etc.

The function requires a string representing the file path as its first argument. However, if an object is passed instead of a string, the function doesn’t know how to handle it and throws this error.

Example

Let’s consider an example where an object is mistakenly passed to the pathinfo() function: 

    // An object representing a file path
    $filePath = new stdClass();
    $filePath->path = "/path/to/file.txt";
    
    // Calling the pathinfo function with an object instead of a string
    $fileInfo = pathinfo($filePath);
    
    // This will throw an error like: pathinfo() expects parameter 1 to be string, object given

In the above example, we have mistakenly passed an object ($filePath) to the pathinfo() function instead of a string. As a result, the error is thrown.

To fix the error, we need to ensure that we pass a string representing the file path to the pathinfo() function. In the above example, it can be fixed as follows: 

    // A string representing the file path
    $filePath = "/path/to/file.txt";
    
    // Calling the pathinfo function with the correct string parameter
    $fileInfo = pathinfo($filePath);
    
    // Now, $fileInfo will contain the file information without any error

In the corrected example, we only pass the string representing the file path to the pathinfo() function, which resolves the error.
