[PHP] Problem z pamięcią Opcje

[shinuexx]

Mam problem z alokacją danych w pamięci. Jestem w trakcie pisania skryptu do otwierania plików Matlaba *.mat i wyskakuje mi błąd:

Kod

Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 24 bytes) in D:\Program Files (x86)\Zend\Apache2\htdocs\homepage\mat2.php on line 146

Zupełnie nie widzę błędu w skrypcie w tym miejscu, ale na wszelki wypadek dodam także kod:
