Strange behaviour while adding a line at the BOF

Hi folks: I'm going nuts trying to add a line of data in the beginning of a text file. The text file looks like: 02_01 03_01 04_01 and so on. When I try to add a line so the text file becomes this: 01_01 02_01 03_01 04_01 I get the following result: _01 03_01 04_01 Here's how I'm attepmting to do it: $foofile = "/usr/local/.../list.txt"; $open_foo = fopen($foofile, "r+"); fputs($foofile,"$temp\n"); fclose($foofile); As a matter of fact the application I'm building is a little more complex than this, but since I'm positive that the error is in the "add-a-line" routine... Please I'm really confused about this. Logically this should work, shouldn't? HELP!
