Laravel DB插入错误:允许的内存大小已用尽 [英] Laravel DB Insert Error: Allowed Memory Size Exhausted

问题描述

尝试在数据库中插入约2万条记录时遇到问题.我注意到，即使我在foreach循环中回显，也没有在命令行中输出任何内容.相反，插入与...有关的〜9440条记录后出现错误.

I'm running into an issue when trying to insert ~20K records into my DB. I notice that even though I'm echoing inside my foreach loop, I'm not getting anything outputted in the command line. Instead, I get an error after inserting ~9440 records relating to...

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 91 bytes) in /Users/me/Sites/Laravel/database/connection.php on line 293

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 91 bytes) in /Users/me/Sites/Laravel/database/connection.php on line 293

这是我的代码(同时使用Eloquent和Fluent进行了尝试):

Here is my code (tried using both Eloquent and Fluent):

<?php

class Process_Controller extends Base_Controller
{
    public function action_migrate()
    {
        $properties = DB::table('raw_properties')->get('id');
        $total = count($properties);

        foreach ($properties as $x => $p) {
            $r = RawProperty::find($p->id);
            $count = $x + 1;

            $prop_details = array(
                'column' => $r->field,
                // Total of 21 fields
            );

            DB::table('properties')->insert($prop_details);

            echo "Created #$count of $total\n";
        }
    }
}

推荐答案

此错误表示您的PHP脚本由于为脚本分配的内存不足而耗尽了内存限制.

This error depicts that your PHP script has exhausted memory limit due to insufficient memory allocated for script.

您需要使用ini_set函数来增加memory_limit 例如ini_set('memory_limit'，'128M');

You need to increase memory_limit using the ini_set function e.g ini_set('memory_limit','128M');
