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

Wordpress用户添加一行:

@ini_set（“memory_limit”、“-1”）;

在wp-settings.php中，你可以在wordpress安装的根文件夹中找到

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.

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;

在Wordpress中切换到一个新主题后，我收到了同样的错误信息。PHP运行的是5.3版本，所以我切换到了7.2。这解决了问题。

写

ini_set (memory_limit’,‘- 1);
