我有一个非特定于用户的大型多维数组〜100Mb-150Mb,目前将其保存在一个JSON文件中。必须使用来自API的数据每分钟更新此数组。
我不确定是否应该使用add_filter( 'gettext', 'change_add_to_cart_message', 10, 3 );
function change_add_to_cart_message( $translated, $text, $domain ) {
global $pagenow;
if( $text === 'WooCommerce status' && $domain === 'woocommerce' && is_admin() && $pagenow === 'index.php' ){
$translated = __( 'WooCommerce summary', $domain );
}
return $translated;
}
或$_COOKIE
进行存储,并避免写入文件(即$_SESSION
)以提高性能。
可能没有内存问题,因为已经使用以下脚本顶部的此设置收集了数据:
fopen(); fwrite(); fclose();
ini_set('max_execution_time', 0);
ini_set('memory_limit', '-1');
set_time_limit(0);
// Config class for path and other constants
require_once __DIR__ . "/ConstEQ.php";
class EquityRecords extends EQ implements ConstEQ
{
public static function getSymbols()
{
//***************** START: ALL SYMBOLS ARRAY ********************** //
// var: is a filename path directory, where there is an md file with list of equities
$list_of_equities_file = __DIR__ . self::SYMBOLS_PATH;
// var: is content of md file with list of equities
$content_of_equities = file_get_contents($list_of_equities_file);
// var is an array(3) of equities such as: string(4) "ZYNE", string(10) "2019-01-04", string(27) "ZYNERBA PHARMACEUTICALS INC"
$symbols_array = preg_split('/\R/', $content_of_equities);
//***************** END: ALL SYMBOLS ARRAY ********************** //
// child and mother arrays are created to help calling equities in batches of 100, which seems to be the API limit.
$child = array();
$mother = array();
// var: is 100 counter
$limit_counter = self::NUMBER_OF_STOCKS_PER_REQUEST;
foreach ($symbols_array as $ticker_arr) {
$limit_counter = $limit_counter - 1;
$symbols_array = preg_split('/\t/', $ticker_arr);
array_push($child, $symbols_array);
if ($limit_counter <= 0) {
$limit_counter = self::NUMBER_OF_STOCKS_PER_REQUEST;
array_push($mother, $child);
$child = array();
}
}
return $mother;
}
public static function allEquitiesSignleJSON()
{
$equity_arrays = EquityRecords::getSymbols();
$base_url = self::BASE_URL . self::TARGET_QUERY;
$current_time = date("Y-m-d-H-i-s");
$all_equities = array();
// ticker: AAPL, GE, AMD
foreach ($equity_arrays as $ticker_arr) {
$ticker = array_column($ticker_arr, 0);
$equity_url = $base_url . implode("%2C", $ticker) . self::END_POINT;
$raw_eauity_json = file_get_contents($equity_url);
$raw_equity_array = json_decode($raw_eauity_json, true);
$all_equities = array_merge($all_equities, $raw_equity_array);
}
$all_equities_json = json_encode($all_equities);
$symbols_dir = __DIR__ . self::SYMBOLS_DIR;
if (!is_dir($symbols_dir)) {mkdir($symbols_dir, 0755, true);}
$raw_equity_file = $symbols_dir . "/" . $current_time . ".json";
$fp = fopen($raw_equity_file, "x+");
fwrite($fp, $all_equities_json);
fclose($fp);
echo "YAAAY! Equity JSON file success at " . __METHOD__ . " ! " . self::NEW_LINE;
}
}
。 128Mb
的最大容量与$_COOKIE
相同吗?答案 0 :(得分:2)
我不确定是否应该使用
$_COOKIE
或$_SESSION
来存储它…
这两种东西都不大可能。
$_COOKIE
映射到用户浏览器中的cookie。 It is limited to 4 kB per cookie, and a total of roughly 80 kB across all cookies.设置较大的Cookie将使对您网站的请求变慢,因此不建议这样做。
$_SESSION
存储在Web服务器上的文件中,并且具有更宽松的大小限制,但为每个用户单独存储。除非您从此API收集的数据是特定于用户的,否则这也不是一个好选择。
如果您的数据确实只是从API收集的,并且应该在所有用户之间共享,那么将其存储在文件中(就像您已经在做的一样!)是一种非常合理的方法。 Cookie无法容纳100 MB,并且将其存储在会话中也无济于事。
