It is unfortunately easy to program in PHP in a way that consumes memory faster than you realise. Copying strings, arrays and objects instead of using references will do it, though PHP 5 is supposed to do this more automatically than in PHP 4. But dealing with your data set in entirety over several steps is also wasteful compared to processing the smallest logical unit at a time. The classic example is working with large resultsets from a database: most programmers fetch the entire resultset into an array and then loop over it one or more times with foreach(). It is much more memory efficient to use a while() loop to fetch and process one row at a time. The same thing applies to processing a file.

COMPOSER_MEMORY_LIMIT=-1 composer require mageplaza/module-core

我们也遇到过类似的情况，我们尝试了顶部给出的答案 报错(' memory_limit ', ' 1 '); 一切工作正常，压缩图像文件大于1MB到KBs。

做的事情:

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

从来都不是好事。如果你想读取一个很大的文件，最好的做法是一点一点地复制它。尝试以下代码进行最佳实践。

$path = 'path_to_file_.txt';

$file = fopen($path, 'r');
$len = 1024; // 1MB is reasonable for me. You can choose anything though, but do not make it too big
$output = fread( $file, $len );

while (!feof($file)) {
    $output .= fread( $file, $len );
}

fclose($file);

echo 'Output is: ' . $output;

我运行以下命令编写器更新，现在正在工作。如果它不能解决你的问题，增加你的内存限制在memory_limit在php.ini文件。

我想分享我在这个问题上的经验!

假设你有a类和B类。

class A {
    protected $userB;

    public function __construct() {
        $this->userB = new B();
    }
}

class B {
    protected $userA;

    public function __construct() {
        $this->userA = new A();
    }
}

这将启动一个对象链的形成，这可能会产生这种问题!
