15070 Keyword Scraper, Cleaner PHP

Straightforward Keyword Scraper script required. I have attached examples of code required for my project. User Inteferace: 1. Form box to enter starting keyword. 2. Special Functions Checkboxes: A. Checkbox to "clean" (eliminate adult keywords) from results. B. Checkbox to create "typos" of keywords with a .php subroutine script. a. Form box to to enter how many keywords should be run through the typo generator, ie. first 500 keywords, first 1000 keywords, the first 333 keywords etc. (this will obviously explode the volume of the final list immensely, so a very efficient process should be used here) C. Check box to select size of keyword phrase to be kept in output, for example no more than 2 words in each phrase, or no more than 5 words in each phrase - up to 6 for this project. 3. Scraper search depth drop down menu, levels 1-6. A. Level 1 means find keyword phrases associated with the starting keyword, when all keywords are found, exit search and print to output. B. Level 2 means run query for Level 1, THEN, start with the first keyword on Level 1's output list and collect all keywords associated with THAT word. (this creates an exponentially larger list...for example, if level 1 search yields 500 keywords, and there are 4 associated keywords for every keyword of level 1, the total output for level two woould be 2000). C. Level 3 means the same process as Levels 1 and 2, but this time querying the results of level 2's final output for more keywords. (Again, this will explode the list exponentially...using the above example of 2000 keyword output for level 2, and 4 associated keywords for each of the 2000 level 2 output, we now have 8000 keywords). D. Level 4 - same process as above, one level deeper. E. Level 5 - same process as above, one level deeper. F. Level 6 - same process as above, one level deeper. 4. Checkbox to save output to txt file. 5. Form input to name output txt file. 6. Form input to select whether or not output to txt should be grouped, ie. txt files of 500 keywords, 1000 keywords, 2500 keywords, or 10,000 keywords, or "OTHER" value. A. Form input for "other" value for output of keywords. 7. Checkboxes to choose services to query: Overture, Yahoo!, Google Keyword Tool, Google Suggestion BETA, Ask, and Snap. 8. Submit Query button and process. Process: 1. Begin with starting keyword input, query selected sites. 2. Collect results. 3. Remove Duplicate words. 4. Remove Adult words if this option selected. 5. Create txt file with name provided in form. 6. Print output words to txt file if only level 1. Sub-levels Process: 1. If Level 2 or more is selected... A. Go to level 2 search mode with level 1's cleaned list and no duplicates. B. Clean Level 2 output. C. Remove duplicate words in level 2 output. 2. If repeat process for each level selected. 3. Once final level has been achieved, clean words (if selected in user input) and remove duplicates. 4. Print to txt file as named in user input. Typo-Creator sub process - See attached Script 1. Open file txt list gathered from the previously completed processes. 2. Create typos for each word on list. 3. Save to txt file "{keyword list name}[login to view URL]". Parsing keyword list into groups of keywords: 1. Open final list of keywords from first two processes. 2. Select first 500, 1000, 5000, or 10,000 as specified by user input. 3. Save each block to txt file "{keyword list name}-Block{N}.txt" where N=what block of keywords is saved in the file, for example if the list is being parsed into groups of 500, the first 500 keywords would be saved as "{keyword list name}[login to view URL]" - Block 2, 3, etc for each remaining group of keywords.
