A couple of useful PHP functions

I've recently added to my home page a count of the number of papers which include the string "xspec". This accesses the new ADSlabs full text search. The html instruction is



where the getXSPECpapers.php file contains

1 - 20 of (.+?)%';
preg_match($regex,$data,$match);
echo $match[1];
?>

This can be modified for any other string by changing the q=xspec section of the URL.

I've also added to my CV page so that it updates the number of citations to each of my papers. The HTML to do this is eg:



where the bibcode argument is the standard ADS bibcode. The getCitations.php file contains

(.+?) abstracts.%';
preg_match($regex,$data,$match);
echo $match[1];
?>
