help with fgets

hi. i'm trying to read in a text file line by line into an array. i've got the following code: $i = 0; while(!feof ($fp)){ $buffer = trim(fgets($fp, 4096)); $photos[i] = $buffer; $i++; } fclose($fp); when i echo $buffer to the screen it prints out hte content of hte file line by line if i echo $photos[i] to the screen it just prints out random numbers and not the content i'd expect (the code i'm using to do this is: $i = 0; while(!feof ($fp)){ $buffer = trim(fgets($fp, 4096)); echo $buffer."<br>"; $photos[i] = $buffer; echo $photos[i]."<br>"; $i++; } fclose($fp); any help would be greatly appreciated thanks. todd kennedy
