What common issues do PHP developers face when trying to upload files using APIs like Fastbill?

One common issue PHP developers face when trying to upload files using APIs like Fastbill is encountering file size restrictions. To solve this, developers can check the maximum file size allowed by the API and ensure that the uploaded file does not exceed this limit. Another common issue is handling file types, where the API may only accept specific file formats. Developers can validate the file type before uploading it to ensure compatibility with the API. 

// Check file size before uploading
$maxFileSize = 5242880; // 5MB limit
if ($_FILES['file']['size'] > $maxFileSize) {
    echo "File size exceeds the limit.";
    exit;
}

// Validate file type before uploading
$allowedFileTypes = ['jpg', 'png', 'pdf'];
$extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
if (!in_array($extension, $allowedFileTypes)) {
    echo "Invalid file type. Allowed types are jpg, png, pdf.";
    exit;
}
