Fatal errors cannot be tracked directly through error_handler(). You need to use register_shutdown_function() to catch those errors.

Example:

<?php
/**
 * Checks for a fatal error, work around for set_error_handler not working on fatal errors.
 */
function check_for_fatal()
{
    $error = error_get_last();
    if ( $error["type"] == E_ERROR )
        log_error( $error["type"], $error["message"], $error["file"], $error["line"] );
}

register_shutdown_function( "check_for_fatal" );
?>

This is a modified example from PHP Manual [Personally Tested & Works]. I haven't used the register_shutdown() here.

<?php

set_error_handler( "log_error" );
set_exception_handler( "log_exception" );
function log_error( $num, $str, $file, $line, $context = null )
{

    log_exception( new ErrorException( $str, 0, $num, $file, $line ) );
}

function log_exception( Exception $e )
{

echo "Some Error Occured. Please Try Later.";
exit();
}

require_once("texsss.php");// I am doing a FATAL Error here

OUTPUT :

Some Error Occured. Please Try Later.
