Unable to access my wp admin

I am unable to access my wp admin .

Showing an Error message

Strict Standards: Only variables should be passed by reference in /home2/tosaleco/public_html/wp-content/plugins/p3-profiler/p3-profiler.php on line 50

Here is the line 50

if ( is_admin() && ‘admin-ajax.php’ == end( explode( ‘/’, $_SERVER[‘PHP_SELF’] ) ) ) {

I had nil knowledge about php. Please let me know what changes in that line will give me access to my wp admin

Will be waiting for the reply.

Thank you.
