This is the format of  etc crontab      ---------------- minute  0 - 59        ------------- hour  0 - 23           ---------- day of month  1 - 31              ------- month  1 - 12  OR jan feb mar apr                    ---- day of week  0 - 6   Sunday 0 or 7  OR sun mon tue wed thu fri sat                                 user-name  command to be executed   I recommend copy  amp  pasting that into the top of your crontab file so that you always have the reference handy  RedHat systems are setup that way by default   To run something every minute             username  var www html a php   To run something at midnight of every day   0 0       username  var www html reset php   You can either include  usr bin php in the command to run  or you can make the php scripts directly executable   chmod  x file php   Start your php file with a shebang so that your shell knows which interpreter to use      usr bin php  lt  php    your code here
