How can i find back links threw php programing ?

i need to develop program to find perfect backlinkg from Google.

can anyone help me ?

 

You could parse google results with link: or use their api as explained here http://stackoverflow.com/questions/2751473/how-to-calculate-google-backlinks-using-php
The amount of requests you can do will be limited however.

 

Wouldn't you want to do links: rather than link:

 

If I wanted to find all backlinks for the keyword ceo to my blog markustenghamn.com I would search "link:markustenghamn.com ceo"
