حصلت علي مهمة لاختبار معرفتي بال php

Task

Encode and Decode conditions

  •    Don’t use Base64 encode decode functions

  •    Every time whenever page refreshes or requesting new page load the encoded data must be changed and result must be same

o For example I am encoding a simple name “ Ahmed Ibrahim” so result must be exact same

  • Same applies for the file encode it and every time even a same file is used to encode the encoding characters must be different

And file upload extensions to be allowed only “pdf”, “jpg”, “jpeg”, “png”, “docx

لكن للاسف لم افهم جيدا المقصود الرجاء المساعدة
