****English The space industry has been stagnant for many years, in 1964 according to NASA and ESA it was possible to send a device to Mars that sent some photos of the planet, the last mission arrived at Mars on 11/26/2018. In this year 2020, 3 new missions were sent , one from the United Arab Emirates, one from China and one from the USA. The 3 estimated to reach Mars in February 2021 . None of these mission has a different proposal that could send strong results, always a vehicle that goes, takes photos and then sends them to Earth, along with measurements that have not been of greater relevance, speaking from my point of view as a world citizen. Today we have interesting technology that could improve all this, but for some strange reason no scientist attached to the exploration agencies occurs to use it. To put it in simple terms, there are many robots that have demonstrated exceptional capabilities and that can be controlled remotely, such devices could already be mass produced an...

If you need to use PHPWord in a hosting environment in which you can't install via composer, you must install it locally on your development machine, then just copy the directory to your hosting provider (normally copy the vendor directory to your root application directory). The only change I needed to do is to have a writable directory where to store the created files. In my case I created "./public/docs" then in the method save: $objWriter->save('./public/docs/my_wordfile.docx'); ********** Si necesita usar PHPWord en un servidor de hosting en el cual no puede instalar usando el composer, lo que debe hacer es instalar en su máquina local, luego solo basta con copiar el directorio a su proveedor de hosting (normalmente copie el directorio vendor al directorio root de su aplicación).

This is a very common solution and normally expressed as a joke to recognize the "Support Engineer" 's main activity: when someone needs to fix something in the computer and calls for support and the supporter says: "please restart your computer." This is not a nonsense solution, in fact if there are some smart question from the supporter and finally decides to tell the user please restart is because of this. Example of questions for a program that is not working on the computer: 1. Have you applied a recent update on the app? R/No 2. Someone else applied an update on your computer? R/No 3. When was the last time your app was working fine? R/A few minutes ago 4. Ok, if your computer is the same in configuration and it fails a few moments ago, it must be something about the operating system exahusted, I think you must restart your computer. R/I already did it, I restarted the computer. 5. Oh, ok, so you are now opening the program and it's still fail...
