PHP Task - read value from File input to MySQL + Get Value from Website and write to txt file

I am in need of a PHP developer to assist me with a task that involves reading a value from a TXT file input and writing it to a MySQL database. Additionally, I need the developer to retrieve a value from a website and write it to a TXT file. [login to view URL] (is wrote by other code) and it writes inside the text file: username,,15451 so first PHP just to check for the Username in the Database , if he excist then add the second value (can be a number from 1 to 10 trillion) and at it into the MySQL field "gems". Second is: There will be a 2 Text Fields: Username Amount send Button thats for withdrawl, so they put they wish username in on what they wanna get the payout the second file is how much they wanna withdrawl (so before its send check if he has enough in MySQL of gems) if he was enough PHP writes a new textfile in folder /withdrawls/[login to view URL] (the username that he want to payout) in the .txt file php put the value: username,gems gems = the amount he withdrawl before the withdrawl is submitted dont forget to take the value from gems in mysql db away so cant double payout. Looking for some long term working :) Ideal Skills and Experience: - Strong proficiency in PHP - Experience with MySQL database - Knowledge of web scraping and data retrieval - Familiarity with data validation and error handling I will provide the file name and location for the TXT output file and am open to discussing any additional details or requirements for the project.
