允许的内存大小为 138412032 字节耗尽（试图分配 20480 字节）

Question

我正在尝试使用 Slim PHP Framework 开发一个 PHP 作曲家应用程序，并尝试像这样对 migrations.php 文件进行更改

<?php

declare(strict_types=1);

require __DIR__ . '/../../src/App/App.php';

try {
    $settings = $app->getContainer()->get('settings');

    $hostname = $settings['db']['hostname'];
    $username = $settings['db']['username'];
    $password = $settings['db']['password'];
    $database = $settings['db']['database'];

    $pdo = new PDO("mysql:host=$hostname", $username, $password); //Possibly the connection
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "DROP DATABASE IF EXISTS $database";
    $pdo->exec($sql);
    echo "[OK] Database droped successfully" . PHP_EOL;

    $sql = "CREATE DATABASE $database";
    $pdo->exec($sql);
    echo "[OK] Database created successfully" . PHP_EOL;

    $sql = "USE $database";
    $pdo->exec($sql);
    echo "[OK] Database selected successfully" . PHP_EOL;

    $sql = file_get_contents(__DIR__ . '/../../database/database.sql');
    $pdo->exec($sql);
    echo "[OK] Tables created successfully" . PHP_EOL;
//    echo "[OK] Records inserted successfully" . PHP_EOL;
    $data = file_get_contents(__DIR__ . '/../../database/companies.json');
    $array = json_decode($data, true);
    foreach($array as $row) {
        $relationships = $row["relationships"];

        $pdo->exec($sql);

    }
    echo "[OK] Json inserted into tables successfully" . PHP_EOL;



} catch (PDOException $e) {
    echo "[ERROR] " . $e->getMessage() . PHP_EOL;
}

我尝试加载一个 companies.json 文件，该文件大小为 78.5MB，当我运行 composer migration 时，我运行进入错误 Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /.../extras/bin/migration.php on line 35.

我还在代码库中使用相同的composer.json

    }
}

并且我在 here.

的 /docker/php7/php.ini 的存储库中添加了一个 php.ini 文件

有人介意告诉我如何增加应用程序的内存限制吗？我对 PHP 很陌生。让我知道是否需要更多说明

Answer 1

我建议您可以通过以下方式设置：

ini_set('memory_limit', '80M');

但是，这是一个糟糕的解决方案，尽量不要将整个 json 文件加载到内存中并使用类似 jsonstreamingparser .

的东西

Answer 2

是128M，设置memory_limit = 256M为例，希望对你有帮助

（在 .ini 中）
