Re: remove characters, add newline & making a twodimensional array

Well, i'm kind of a newby, but this is what i would like to do in php: 1. i'm writing all instances of a mysql table to a txt file, but when i add "\n" to go on on the next line, in the txt file there is a square printed. When i try to import the txt file into ms access, the square is not recognized by this program to represent a newline.. how can i add a newline to a txt file, that actually IS a newline (or better: hard return) and that will be recognized as one, when reading the file into another program? Newline in dos/windows text files is "\r\n"

2. a array contains a string of text, multiple words and interpunction. my first question: how can i remove the interpunction ( i know how to strip slashes and trim spaces..)?

strtr() -- cantains also an example secondly, after this, i would like to count all double

entries. f.e. when the word computer occurs twice in the sentence, i would like to make an array that is twodimensional: word-number of occurences (f.e. 'computer' '2'). How do i do that, for i don't really understand the phpmanual-explanation about this topic. And thirdly: how do i get both facts (word and number) out of the array? (all this has to produce a word-frequecylist, so if anybody has a clue how to do that......)

First you need to get and array of all words - use explode() or preg_split(). Then you need to loop the array and count the words.

3. how can i upload an image to my server and then call the image back into a webpage, just by using php?
