Description: The file upload limit in web applications refers to the maximum size of files that can be uploaded to a server through a web form. This parameter is crucial for resource management, as it helps control disk space usage and server load. In PHP, this limit is set using the ‘upload_max_filesize’ directive in the ‘php.ini’ configuration file. Additionally, there is another directive called ‘post_max_size’, which also influences the total size of data that can be sent through a form. If a file exceeds the established limit, the server will reject the upload and return an error. This mechanism is essential to prevent abuse, such as overloading the server with excessively large files, and to ensure a smooth user experience. Properly configuring these limits is vital for developing secure and efficient web applications, allowing developers to manage resources and user experience effectively on their platforms.
