------------------------------------------------------------------



php.ini
memory_limit = 700M


php-script
for ($i=1;$i<10000000;$i += 40000) {
	echo '<div style="float:left; width:100px;">'.$i.'</div><div
style="float:left;">'.round((memory_get_usage()/1048576),2).' MB</div><div
style="clear:left;"></div>';
	for ($j=1;$j<40000;$j++) {
		$wert[] = $i+$j;
	}
	
}
