Re:Subject: Difficult String/number fomatation plz hlp!

Try split() function which splits a string into an array based on a regular expression (PP manual) : this is different than explode() which splits on a fixed delimiter. eg (this is in the manual ): $stringparts=split ('[,-]', $string); Will split $string= "1,3, 3-6, 8" into individual array elements. Don't forget to remove spaces from the input first, str_replace(" ","",$string) or add spaces as a non-separator to your regex. Then use array_unique(array,array) to remove duplicates. Don't you just *love* PHP :-) Finally recombine the array in your desired format (I have no idea what rules the 'correct form' takes - you have to write that yourself :-) Cheers, Neil Smith.

Content-Transfer-Encoding: 7bit Subject: Difficult String/number fomatation plz hlp! Hi! I have a textfield wich allows any number of integers seperated with " ", "," or "-"... I need this input to be formated in two steps: First into a sequence of numbers into an array, lowest first... Second to the correct form of the initial input... Example: User input: "1,3, 3-6, 8" (string) First step: 1,3,4,5,6,8 (array) second step: "1,3-6,8" (string) please help me with this one! I don't mind using ereg-functions though I'm not good at it myself...
