If you're only interested in appending to the end of a file, then use $fp = fopen('filename', 'a+'); and fputs() all you want. But, if you want to stick stuff into the middle... # Real process uses file(), # but for test, set Content manually. $Content[] = 'The start of the content array.'; $Content[] = 'Some more stuff.'; $Content[] = 'And yet more stuff.'; $Location = array_search('Some more stuff.', $Content); $New[] = 'Why, here is some new stuff'; $Final = array_merge( array_slice($Content, 0, $Location + 1), $New, array_slice($Content, 0 - (count($Content) - $Location - 1)) ); # In your process, you'll really want to insert # implode('', $Final) into the file with fputs(), # but, hey, this is a demonstration. print_r($Final); --Dan -- PHP classes that make web design easier SQL Solution | Layout Solution | Form Solution sqlsolution.info | layoutsolution.info | formsolution.info T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y 4015 7 Av #4AJ, Brooklyn NY v: 718-854-0335 f: 718-854-0409
