I was also having the same problem, looked for phpinfo.ini, php.ini or .htaccess files to no avail. Finally I have looked at some php files, opened them and checked the codes inside for memory. Finally this solution was what I come out with and it worked for me. I was using wordpress, so this solution might only work for wordpress memory size limit problem. My solution, open default-constants.php file in /public_html/wp-includes folder. Open that file with code editor, and find memory settings under wp_initial_constants scope, or just Ctrl+F it to find the word "memory". There you will come over WP_MEMORY_LIMIT and WP_MAX_MEMORY_LIMIT. Just increase it, it was 64 MB in my case, I increased it to 128 MB and then to 200 MB.

// Define memory limits.
if ( ! defined( 'WP_MEMORY_LIMIT' ) ) {
    if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
        define( 'WP_MEMORY_LIMIT', $current_limit );
    } elseif ( is_multisite() ) {
        define( 'WP_MEMORY_LIMIT', '200M' );
    } else {
        define( 'WP_MEMORY_LIMIT', '128M' );
    }
}

if ( ! defined( 'WP_MAX_MEMORY_LIMIT' ) ) {
    if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
        define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
    } elseif ( -1 === $current_limit_int || $current_limit_int > 268435456 /* = 256M */ ) {
        define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
    } else {
        define( 'WP_MAX_MEMORY_LIMIT', '256M' );
    }
}

顺便说一句，请不要做下面的代码，因为这是不好的做法:

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

如果您试图读取一个文件，这将占用PHP中的内存。例如，如果您试图打开并读取一个MP3文件(例如，$data = file("http://mydomain.com/path/sample.mp3"))，它将把它全部拉到内存中。

正如Nelson所建议的，如果您确实需要使用这么多内存，您可以提高您的最大内存限制。

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。

我没有更新主机，数据库是只读的。Joomla需要编写会话，但无法完成。

如果你正在使用Laravel，那么可以使用以下方法:

public function getClientsListApi(Request $request){
      print_r($request->all()); //for all request
      print_r($request->name); //for all name 
}

而不是

public function getClientsListApi(Request $request){
      print_r($request); // it show error as above mention
}
