i am new to cron job . i studied some basics about cron job . i can able to call php using cron tab. By using following command in /etc/crontab
10 * * * * root /usr/bin/php /var/www/PATH TO SCRIPT/email.php
In email.php i have following code
#!/usr/bin/php
<?php
mail ("examplemail@mail.com", "Cron Successful Public HTML!","Hello World from mycron.php!");
?>
For every 10mins i am getting mail. But i need to know is there any way to call cron job from php ( invoke cron from php) i get some idea by surfing but i am not able to figure out the exact way to do my job . Here is code which i used to add job by using php
exec('echo -e "crontab -e
2 * * * * /usr/bin/php /var/www/PATH TO THE SCRIPT/crontest1.php" ');
Its not working for me. can anyone please guide me how to call or add cron from php. so tat i can send mail by executing php file & can able change time interval in php file itself.
