How can the file content be stored in a variable when using HTTP methods in PHP?

When using HTTP methods in PHP, such as POST or PUT, to upload a file, you can store the file content in a variable by accessing it through the $_FILES superglobal array. The $_FILES array contains information about the uploaded file, including its temporary location on the server. By reading the content of the file from this temporary location, you can store it in a variable for further processing. 

// Check if the file was uploaded successfully
if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    // Get the temporary location of the uploaded file
    $tmpFilePath = $_FILES['file']['tmp_name'];

    // Read the content of the file into a variable
    $fileContent = file_get_contents($tmpFilePath);

    // Now $fileContent contains the content of the uploaded file
} else {
    // Handle the file upload error
    echo 'File upload failed with error code: ' . $_FILES['file']['error'];
}
