Я вызываю следующие две функции внутри функции с именем RebuildSummary ()

create_summary ()insertdatafromfile ()1. функция create_summary

Функция create_summary извлекает данные о деятельности из базы данных и выполняет циклический просмотр действий, используемых для каждого цикла, и вставляет данные в текстовый файл ниже, как показано ниже:

zfilename71801404123.txt

A|201309|R|C|2|014000956|014000956|2200|201211|M|3118.72|35215.12|1639.96|40749.29|46183.13|44653.83|1529.3|||423|9999|EVERGREEN IMPLEMENT INC 
A|201309|R|C|2|014000956|014000956|2201|201211|M|0|13.86|0|15.22|13.86|15.22|-1.36|||423|9999|EVERGREEN IMPLEMENT INC 

2. функция вставки данных из файла

Функция insertdatafromfile прочитает содержимое того же текстового файла [zfilename71801404123.txt] и вставит его в сводную таблицу с помощью команды LOAD DATA.

Код

function RebuildSummary() {
    $random = date('dmyhis');
    $zfilename = "zfilename".$random;
    create_summary($zfilename);
    insertdata($zfilename);

Мой вопрос:

Я получаю приведенную ниже ошибку при вызове функции RebuildSummary.

[17-Apr-2014 03:54:42 America/Los_Angeles] PHP Fatal error:  Out of memory (allocated 1517289472) (tried to allocate 64 bytes) in C:\HostingSpaces\wwwroot\system\database\drivers\mysql\mysql_result.php on line 162

У меня достаточно памяти на стороне сервера, но как система отображает эту ошибку «Недостаточно памяти»
