The method getElementsByTagName may return NULL ( acording to documentation here), so you need to check for not- null variable: $ cols = $ rows- > item( $ i) if(! null( $ cols) ) { $ cols = $ cols- > getElementsByTagname( ' td' ) } else. thus in the first url extracting $ items = $ dom- > getElementById( ' threads' ). returns NULL instead of the relevant object.

Fatal error: Call to a member function getElementsByTagName( ) on a non- object in. Because you failed to load the data with file_ get_ contents( ) the DOM structure had nothing hence the error. To solve it you need to check. I think the problem is this comparison: if ( $ xml- > documentElement- > getElementsByTagName( $ tagname)! If nothing is found, getElements returns an empty array which is never equal to the number 0, so this always.
