我有两个PHP脚本正在从API加载许多可变资源，导致响应时间长达2.2秒到4秒。如何减少响应时间和提高效率的任何建议将非常感激？减少服务器响应时间加载许多资源
第一个脚本
require('path/to/local/API_2');
//Check if user has put a query and that it's not empty
if (isset($_GET['query']) && !empty($_GET['query'])) {
//$query is user input
$query = str_replace(" ", "+", $_GET['query']);
$query = addslashes($query);
//HTTP Request to API_1
//Based on $query
//Max Variable is ammount of results I want to get back in JSON format
$varlist = file_get_contents("http://ADRESS_OF_API_1.com?$query&max=10");
//Convert JSON to Array()
$varlist = json_decode($varlist, true);
//Initializing connection to API_2
$myAPIKey = 'KEY';
$client = new APIClient($myAPIKey, 'http://ADRESS_OF_API_2.com');
$Api = new API_FUNCTION($client);
$queries = 7;
//Go through $varlist and get data for each element in array then use it in HTML
//Proccess all 8 results from $varlist array()
for ($i = 0; $i <= $queries; ++$i) {
//Get info from API based on ID included in first API data
//I don't use all info, but I can't control what I get back.
$ALL_INFO = $Api->GET_FUNCTION_1($varlist[$i]['id']);
//Seperate $ALL_INFO into info I use
$varlist[$i]['INFO_1'] = $ALL_INFO['PATH_TO_INFO_1'];
$varlist[$i]['INFO_2'] = $ALL_INFO['PATH_TO_INFO_2'];
//Check if info exists
if($varlist[$i]['INFO_1']) {
//Concatenate information into HTML
$result.='
<div class="result">
<h3>'.$varlist[$i]['id'].'</h3>
<p>'.$varlist[$i]['INFO_1'].'</p>
<p>'.$varlist[$i]['INFO_2'].'</p>
</div>';
} else {
//In case of no result for specific Info ID increase
//Allows for 3 empty responses
++$queries;
}
}
} else {
//If user didn't enter a query, relocates them back to main page to enter one.
header("Location: http://websitename.com");
die();
}`
注：$结果等于从角落找寻每一次循环中的HTML信息。
注意：几乎所有的时间都花在
for ($i = 0; $i <= 7; ++$i)循环中。
第二个脚本
//Same API as before
require('path/to/local/API_2');
//Check if query is set and not empty
if (isset($_GET['query']) && !empty($_GET['query'])) {
//$query is specific $varlist[$i]['id'] for more information on that data
$query['id'] = str_replace(" ", "+", $_GET['query']);
$query['id'] = addslashes($query['id']);
//Initializing connection to only API used in this script
$myAPIKey = 'KEY';
$client = new APIClient($myAPIKey, 'http://ADRESS_OF_API_2.com');
$Api = new API_FUNCTION($client);
$ALL_INFO_1 = $Api->GET_FUNCTION_1($query['id']);
$query['INFO_ADRESS_1.1'] = $ALL_INFO_1['INFO_ADRESS_1'];
$query['INFO_ADRESS_1.2'] = $ALL_INFO_2['INFO_ADRESS_2'];
$ALL_INFO_2 = $Api->GET_FUNCTION_2($query['id']);
$query['INFO_ADRESS_2.1'] = $ALL_INFO_3['INFO_ADRESS_3'];
$ALL_INFO_3 = $Api->GET_FUNCTION_3($query['id']);
$query['INFO_ADRESS_3.1'] = $ALL_INFO_4['INFO_ADRESS_4'];
$ALL_INFO_4 = $Api->GET_FUNCTION_4($query['id']);
$query['INFO_ADRESS_4.1'] = $ALL_INFO_5['INFO_ADRESS_5'];
$query['INFO_ADRESS_4.2'] = $ALL_INFO_6['INFO_ADRESS_6'];
$ALL_INFO_5 = $Api->GET_FUNCTION_5($query['id']);
$query['INFO_ADRESS_5.1'] = $ALL_INFO_7['INFO_ADRESS_7'];
}
$result = All of the $query data from the API;
} else {
//If no query relocates them back to first PHP script page to enter one.
header("Location: http://websitename.com/search");
die();
}`
注：Similiarly的第一个脚本，大部分时间都花在正从次级API信息 。 $ varlist [$ i] ['id'] = $ query ['id']。注意：在第二个脚本中，第一个API由第一个脚本页面中的单个 特定变量替换，因此$ varlist [$ i] ['id'] = $ query ['id']。
注意：同样，$ result是HTML数据。
API响应多长时间一次？我的意思是，如果这就像是你正在拉的新闻馈送，它不会经常改变。您可以使用cron来拉取和缓存请求，然后从缓存副本中提取。 –
API响应在查询更改时发生更改，这是非常频繁的。尽管可能值得花时间查看是否有某些更常见的查询。 – John
如果API2有一个可以获取多个结果的方法，那么您可以将http请求从8减少到2.除此之外，还可以缓存您所能做的所有事情。如果你仍然不能缩短时间，请确保你异步地调用这个代码（例如使用ajax），这样你可以向用户显示一些建议进度的信息（微调器，进度条等） – Steve
