Thanks to Dan, whose above comment provided a key to solve the issue of how to append to a file. After, using phpinfo(); I made sure my installation of PHP had the requisite settings mentioned in the text to the manual entry for fopen(), I was puzzled as to why my use of fopen() with the append option 'a' (append option) didn't work. Then I read a comment contributed to Appendix L (http://us2.php.net/manual/en/wrappers.php) that the append option 'a' for fopen() doesn't work as expected. The writer suggested using the 'w' option instead, which I found did work. But the 'w' option (write option) overwrites everything in the file. The question remained how to accomplish appending. Following Dan's suggestion about the 'r+' option, I tried this, which works fine: $string = "Message to write to log"; $filehandle = fopen ("/home/name/sqllogs/phpsqlerr.txt", 'r+'); fseek ( $filehandle,0, SEEK_END); fwrite ( $filehandle, $string."\n" ); fclose ($filehandle); ---- Manual Page -- http://www.php.net/manual/en/function.fseek.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52929 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52929&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52929&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52929&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52929&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52929&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52929&report=yes Search -- http://master.php.net/manage/user-notes.php
