    I need a piece of software that monitors a specified instagram user"s feed, and reports back to me (via email) when another specified user comments on their feed.i.e. User"s feed to monitor: @maryCommentor to monitor @bobMary posts a photo of a dog at 10:00amBob comments on Mary"s dog photo at 2:00pmSoftware sends me an email with a link to the photo, a copy of the comment, and the precise time that Bob"s comment was made.This seems difficult to monitor as Instagram doesn"t seem to publish the time a comment is posted, so this would require monitoring of the feed on a pretty frequent basis.The software could be cloud based (that"s probably best), or could run on my desktop (mac) if easier.

    I have a script in PHP. It reads from CSV and inserts several records in a MySQL database. Insertion in general works fine however, there is a bug with dates.CSV contains "...7,07/21/2014,07/21/2014,AAHR7709..." fields are coma separated.Last programmer used this sentence $value = eregi_replace("/","-",mysql_fecha($value));Result, in MySQL i am getting "0000-00-00" in field content.Rest of the files import is working fine, just have trouble with 4 date fields.Let me know if you can fix this.

    Hello,My PHP script has been hacked and it redirects to random URLS predefined by the hacker. He uses subdomains of other hacked websites. We are unable to find the URLS of the redirections in my PHP script database so searching for them in database is useless. The hacker maybe uses an URL rotator but not sure.I can give you access to the FTP of my PHP script and access to the database with MYPHPADMIN. The random redirections occur about once every 24 hours approximately when browsing on the script or simply visiting the PHP site. whenever a connection to the database is done by the script. Previously a coder checked and failed to find the issue. You must be a real professional to bid for this project. No time wasters please.We have put the php code in debugging mode but the redirections do not appear in logs.It"s older PHP script used to track and redirect website traffic that runs on dedicated server. php.ini file on server looks clean.Please bid only if you have huge experience in hacking, security, php and mysql.Thanks
