Is there any way I can execute a PHP script from MySQL?

问题:

I want to invoke and execute a PHP script from a MySQL procedure. Is this possible?

CREATE PROCEDURE simpleproc (OUT param1 INT)     BEGIN          Call my php script here     END// 

[EDIT]
I am in fact trying to raise an event when a condition is met ― for instance when my table field value matches the current time. Then, I want to capture the event and send an email.

It's possible, See the MySQL FAQ for an explanation of how

Can triggers call an external application through a UDF?

But it's likely to be bad design on your part if you have to resort to this

DELIMITER @@  CREATE TRIGGER Test_Trigger AFTER INSERT ON MyTable FOR EACH ROW BEGIN  DECLARE cmd CHAR(255); DECLARE result int(10); SET cmd=CONCAT('/usr/bin/php ', '/home/test/beta/demo.php'); SET result = sys_exec(cmd);  END; @@ DELIMITER ;

For solve your problem you can create table for tasks. From stored procedure you can put to this table any string for task. On server you can run PHP script by crontab. Script will check this table and make some operation.
