Pixel Javascript

I need a javascript file to send events to a php process (the php script I've already done) the javascript must be called in the same way as the facebook pixel, example: <script> !function(f,b,e,v,n,t,s) {if([login to view URL])return;n=f.fbq=function(){[login to view URL] [login to view URL](n,arguments):[login to view URL](arguments)}; if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0'; n.queue=[];t=[login to view URL](e);t.async=!0; t.src=v;s=[login to view URL](e)[0]; [login to view URL](t,s)}(window, document,'script', '[login to view URL]'); fbq('track', 'PageView'); </script> They can have several fbq set at different locations on the page, and all of these fbq events must be located by the script, and sent to PHP to process one by one.
