457400 modify text files

Hi I have 3 php files , every file has 10,000 lines ( a total of 30,000 lines ) I need someone to check every lines on the files and to modify where is needed. What to modify? there can be found links like: $urls[] = '[login to view URL]' . $domainshort . '/posts/taringa/4128234/[login to view URL] and $urls[] = '[login to view URL]' . $domainshort . ' The chosen for this project will have to edit the lines that are looking like first sample link by adding at the end right after .html this " '; " (without comas), the link will look like this: $urls[] = '[login to view URL]' . $domainshort . '/posts/taringa/4128234/[login to view URL]'; For the second sample link need to delete this " . ' " after $domainshort and to replace it with " ; " , the link will look like this: $urls[] = '[login to view URL]' . $domainshort; If you are a patient person then you can finish this project. Please, only serious persons. Contact me via PMB if there are any questions.
