致命错误:尝试备份数据库时,允许的内存大小为33554432字节(尝试分配91字节)错误

I got Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 91 bytes) error while trying to backup database on online rest server using Codeigniter dbutil backup() function.

Here is my code:

    $this->load->dbutil();
    $backup =& $this->dbutil->backup(); 
    $this->load->helper('file');
    write_file('./uploads/db/mybackup.gz', $backup);

I can't find out where I am doing wrong.

    You need to increase your script memory by using this:

    ini_set('memory_limit', '-1'); 
    

    You need to use this line at the top of file.

    By increasing memory_limit your script will take unlimited memory usage of server.

    If you have access on php.ini file than you can increase limit from php.ini file otherwise you need to add this line.

    Side note:

    If you think unlimited memory will be effected on other areas than you can set custom value as:

    ini_set('memory_limit', '512M');  //increase size as you need
