[SOLVED] $10 paypal for quick help

[tommyda]

I need some help building a function that searches a specified page on an external site for a line of code (link), then returns true or false depending on whether it is there or not.

 

I know it is possible because directorys use this function.

 

I am willing to pay $10 though paypal or moneybookers to the first one who can help me

 

Thanks for reading

content = file_get_contents("www.google.com")

 

That will get you the source code

 

Now, how do you want to search for this line?

 

Can you view the source of the site and paste the line you want, then we will know how to search for it

[tommyda]

Ok just a link <a href="www.mysite.com">just a link</a>

[jaymc]

View the source, does that link sit on its own on 1 line

 

See, you will need to use regex to dig out that link, in which case you will need to give regex some rules to search by

 

But if the website changes there code often, then it can screw things up

 

For example today that link might be on line 923, where as tommorow it may be on line 966

[tommyda]

So how do the directorys do it?

 

Directorys tell you to copy and paste a line of code then they search to see if its there and if it is they add your listing automatically

 

This is exactly the function i need.

[jaymc]

Yeh.. but its getting that function

 

Unless it is piblically available, you will need or have someone write it

 

Which is why its important to know how there source is wrote

 

A function will need to know how and what to read in order to select the criteria you are looking for

 

Regex, line numbers, what ever...

 

Unles there is some super pre made function that can do it...

Surely the following will work, won't it?

 

<?php

$content = file_get_contents("http://www.google.co.uk"); // Loads the source code into a string

if (stristr($content, '<a href="www.mysite.com">just a link</a>')) /* If that link is in the string it returns true, if not, it returns false. */ { 
return true;
}
else {
return false;
}

?>
