How to Resolve Warnings from file_get_contents() in PHP

When accessing remote URLs using the file_get_contents() function, you may encounter a warning if the protocol (e.g., "http://") is omitted from the URL string.

Step 1: Check the Return Code

To handle this issue, you can check the return code of file_get_contents(). If the function returns FALSE, it indicates an error. In such cases, you can implement error handling logic within the following conditional statement:

if ($content === FALSE) {
    // Handle error here...
}

Step 2: Suppress Warnings

Another approach is to suppress the warning by using the error control operator (@) before the function call:

$content = @file_get_contents($site);

This syntax will intentionally suppress any warnings or notices generated by the file_get_contents() function. However, it is important to note that suppressing warnings may conceal underlying issues in your code. It is generally better to handle errors explicitly to ensure the proper functioning of your script.
