File delete help

[steviez]

Hi,

 

I have built a captcha system that saves the captcha to a temp folder with the file name captcha_CURRENT_TIME_STAMP where CURRENT_TIME_STAMP is the unix time.

 

I want to delete images older than 5mins old by reading the time stamp on the file name. My question is this:

 

How can i loop through the image folder and read the time stamps on the file name and delete all images older than 5mins?

 

Thanks

Try saving the image name as a timestamp. eg: 200110112312 / YYYYMMDDHHMM.

Unless you can use CRONJOB, suggest maybe each time a person visited the captcha page, do the clean up as well.
