PHP script - modify output text

I need a simple php application. This is how it works. 1. There are four input fields. a. variable name b. number of lines c. number of variables d. input text (it will accept very long texts) 2. There will be one output text field. (Output generated by the script). 3. There will be 2 buttons: GO and RESET (GO process the application, RESET clears the fields). 4. Above the output field, there will be a space for messages (error, success, etc). This is how it should work: 1. User sets a variable name. 2. User sets number of lines to count. (the count is defined by an "." and the next two letters following are a "space" and "any letter in caps". 3. The user will set the number of variables 4. The user will paste a text. When the user clicks on GO, the app will process the text. a. the character " will be transformed into " b. the character ' will be transformed into ' Then the app will show the output. To explain how the output will be, I will put an example. EXAMPLE: variable name = animals number of lines = 2 number of variables = 3 Text field Dog is good. Cat is bad. This example has an etc. but it is a good example. "I pet dogs". I'd be here. Mouse is small. The example is almost finished. OUTPUT animal [1] = "Dog is good. Cat is bad"; animal [2] ="This example has an etc. but it is a good example. "I pet dogs"."; animal [3] = "I'd be here. Mouse is small"; Alert message above output "There was excess text". Possible alert messages will be: Not enough text. Excess text. Processed.
