Using crontab in Ubuntu to execute php code wangking writes that in website development, php code will inevitably be executed on a regular basis. php does not have a timer like java, so it can only be replaced by crontab .??? Edit the crontab file to view the specific writing specifications. it is very convenient (vimetccrontab ):???? The writing rules are as follows: # execute php code using crontab in mhdommondowuserc Ubuntu

# m h dom mon dow user  command17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )#

*/1 * * * * root wget -q -O /dev/null http://www.rewufeng.com/

? ? The daily php code execution is:

59 23 * * * root wget -q -O /dev/null http://www.rewufeng.com/
