Use of codeigniter memory

I made my first application in codeigniter, at first it was working all right. However when I looked at the server memory, it is very high, it starts with little use, and with each request it increases the use and does not release more. I don’t know what to do at the moment. I’ve used the code $db['default']['save_queries'] = FALSE;

But it didn’t work, I added the code

function __destruct() {
    unset($this);
}

to try to free up the memory used in $this, but it didn’t do much good either.

Any idea how to release the memory used?

Thank you

  • it would be good to make a Profiling of the application, I have a question about it, so far only know zend studio as a good tool http://answall.com/questions/28784/profiling-php-debug-tempo-de-execu%C3%A7%C3%A3o

  • I’ve seen the Codeigniter give a few bugs anyway. For example: I’ve done a test, sending great data via POST (form) in a system Codeigniter, and the same generated a fatal error (memory exhaustion).

  • Instead of unset($this), tries to trade for $this->db->close() in the main model :)

I have also had problems with excess memory usage and wrote this short cycle to free everything at the end of each application load.

Do print_r of memory_get_usage()and memory_get_peak_usage() to see the before and after running the cycle:

// DEVELOPMENT
print_r(memory_get_usage()); echo '<br>'; // Antes
print_r(memory_get_peak_usage()); echo '<br>';

foreach (array_keys(get_defined_vars()) as $var){
    unset($$var);
}

// DEVELOPMENT
print_r(memory_get_usage()); echo '<br>'; // Depois

This memory overflow can be the automatic saving of the last query, you can use $this->db->save_queries = false; or change the config/database.php file to 'save_queries' => FALSE,

Look I think it may be the way it was developed, the CI makes many includes. the more $this->load use the more memory will consume.

But it also has to see if the memory consumption is php or database.
