I have a string coming from a form. Should I identify with PHP language in which it was written. I have seen that there are methods with the Google API but I think there are two problems, the first is that after a defined number of research I have to pay, the second that I get requests from libreirie Additional Zend I can not install on my hosting. Maybe I'm wrong?
Is there a way 100% free and does not require libraries difficult to install on a Hosting?
