问题描述
我正在编写一个codeigniter应用程序，执行查询时遇到以下致命错误.
I'm writing a codeigniter application, upon doing a query i get hit with the following fatal error.
我可以增加允许的内存大小，但是似乎问题可能更加严重，如果这是内存泄漏，我只是给php更多的内存.查询甚至不那么密集，它只返回一行数据.
I could increase the allowed memory size, but it seems that the issue could be much more graver, that if it is a memory leak, i'd just be giving php more memory to play around with. The query is not even that intensive, it just returns one row of data.
这是我的控制人
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Invest_webhook extends CI_Controller {
private $web_msg = null;
private $proceed = 1;
private $data = null;
private $receive = null;

$data = array_merge($data,$this->lang->language);

$this->parser->parse('dashboard/'.$page);
$this->parser->parse('dashboard/footer');
}
public function webhook(){
echo memory_get_peak_usage()."<br/>";
//$update = file_get_contents("php://input");
//$update = json_decode($update,true);
$update = array(
'notification_id' => '57233292b6a3d133e9c83822',
'delivery_attempt' => 1,
'type' => 'address',
'data' => Array(

if($receive == $expect){

return true;
}

return false;
}

}

$einv = $this->member['inv'];
settype($einv,'float');
$new_inv = $einv + $this->receive;
$this->member['inv'] = $new_inv;
$this->member['last_inv'] = 'NOW()';
$this->data['confirmed'] = 1;
if($this->invest->update_investment($this->data,$this->member)){
$this->web_msg = 'inv_complete';
$this->complete = 1;
return true;
} else {

return false;
}
}
private function get_investment_data($address){

}
private function log($text){
$file = fopen(APPPATH."/logs/investments/log.log",'a');
fwrite($file,$text);
fwrite($file,"\n");
fclose($file);
}
}
这是我的模特
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Invest_model extends CI_Model {
public function __construct(){
parent::__construct();
}
public function investment_data($address){
$this->db->where('address',$address);
$this->db->where('confirmed',0);
$f = $this->db->get('investments');
return $f->result_array();
}
public function current_investment($tid){
$this->db->select('inv');
$this->db->where('tid',$tid);
$f = $this->db->get('users');
$f = $f->row_array();
return $f;
}
public function get_member_data($tid){
echo "<hr/>";
echo memory_get_peak_usage()."<br/>";
$this->db->where('tid',$tid);
echo memory_get_peak_usage()."<br/>";
$f = $this->db->get('users');
echo memory_get_peak_usage()."<br/>";
return $f->row_array();
}
public function update_investment($inv,$member){
$this->db->trans_begin();
$this->db->set($inv);
$this->db->where('address',$inv['address']);
$this->db->update('investments');
$this->db->set($member);
$this->db->where('tid',$member['tid']);
$this->db->update('users');
if($this->db->trans_status() === FALSE){
$this->db->trans_rollback();
return false;
} else {
$this->db->trans_commit();
return true;
}
}
}
我不是在哪里可以进一步优化它，这是非常简单直接的，如果这是我逻辑上的问题，希望比我更好的头脑能够发现并指导我.
I am not as to where i can optimize this further, its pretty simple and straight forward, if its a problem in my logical appraoch, hopefully a better mind than mine will be able to spot and guide me further.
谢谢.
推荐答案
您的代码看起来不错.检查是否重复调用某些函数.
Your code looks fine. Check if some function is getting called repeatedly.
您可以使用
ini_set('memory_limit', '-1');
作为临时解决方案.或只是增加memory_limit
as a temporary solution. or just increase the memory_limit
检查您的php.ini文件.如果采用以下格式，
Chceck you php.ini file. If it is in the below form,
memory_limit=8G
以 MB
memory_limit=8192M
您也可以像在代码中那样
You can also do it in your code like
ini_set('memory_limit', '8192M');
