PHP parsing project

Hello! I need a PHP code which parses a multi array variable to sample and collect keywords and keyword phrases. Please find the complete project description deeper. [the scape here is too small I think] ## Deliverables Let me start with an example how the content of the variable that have to be parsed may look like: Array ( [title] => Array ( [0] => Alice DSL ab 14,90?'?/M* [1] => o2 DSL Flatrate [2] => Kabel Internet Telefon TV [3] => DSL Flatrate [4] => Festnetz+DSL trotz Schufa [5] => DSL Preisvergleich [6] => Hochwertige SDSL Leitung [7] => 1 Woche kostenlos testen [8] => SEO Tools XOVI [9] => PC Leistung Verbessern [10] => &quot;Richtig Fett Abnehmen&quot; [11] => Tagesgeld-Vergleich [12] => Adwords Optimieren [13] => Arcor Internet Flatrate [14] => Suchmaschinen-Marketing [15] => Flatrate Vergleich [16] => 14 Tage Diät mit Erfolg [17] => Kostenlose Übungen [18] => Unitymedia DSL [19] => für nur 0,03 C/Min Surfen ) [text] => Array ( [0] => Superflexibel ohne feste Laufzeit: Verbinden, ohne sich zu binden!

The amount of entries is variable. May be less than 20 but never more than 20. I am only interested in the first array. Just ignore array 2 and 3. The first step tat is to do is to delete all words in array 1 which are written in a txt file. On the webserver the file's name is filterlist.txt. For building the code just use a txt file with the following words in it: aber als am an auch auf aus bei bin bis bist da my Also all numbers from 0 to 9 have to be deleted ["1304" as example has also completely to be deleted]. And the special characters ,.?;- also have to be deleted. Now the text have to be parsed twice. The first time every single word must be checked. If it is new, it must be written in an array. If it is already part of the array, the counter have to be set up. For example: We habe the text "hello my friend, where are you my friend, where?" So we first have to delete all we can find in the filterlist are receive: "hello friend where are you friend where" The array your code should build have finally to contain: $single[0] = "friend;2"; $single[1] = "where;2"; $single[2] = "hello;1"; $single[3] = "are;1"; $single[4] = "you;1"; So only the word "friend" appears twice in the text. Every other word only once. Please start the array with the highest number (here: 2) and count down. Okay, now to the second parsing step. The text is the same (after deleting the words and characters from the filterlist) but now do noch check single words, check now always two words together. So all available word pairs from our example are hello friend friend where where are are you you friend friend where As you can see only one word pair appears twice: "friend where". So the array for this second paring is: $double[0] = "friend where;2"; $double[1] = "hello friend;1"; $double[2] = "where are;1"; $double[3] = "are you;1"; $double[4] = "you friend;1"; That's it!
