我试图让我的代码在发送到的url没有所需的变量时工作。
这是错误：
E_WARNING：type 2 - file_get_contents（链接）：无法打开流：HTTP请求失败！未找到HTTP / 1.1 404 - 第23行
我的代码转到此用户页面，一切正常：
但是当它转到此用户页面时会出错：
如果在网址中没有任何内容，因为它没有显示任何内容以及何时显示它，我会做什么。但出于某种原因，我无法让它与两者合作。
这是我的代码：

这是你想要做的吗？
PHP将字符串视为字节数组。如果字符串长度大于0，而不是检查字符串是否为空，我想检查是否设置了第一个字节。有些人认为它不那么人性化，但仅仅是某些人。
使用isset($mystring[0])查看字符串的长度是否至少为一个字符。
file_get_contents之前的@符号用于错误抑制。如果无法找到文件，@会阻止错误显示在浏览器中。

您应该能够检查文件内容，以确定它具有所需的数据。
<?php
$claw = file_get_contents('https://euw.api.pvp.net/api/lol/euw/v1.3/stats/by-summoner/' . $id . '/ranked?season=SEASON2016&api_key=' . $apiKey);
if(false === empty($claw)) {
$gaza = json_decode($claw);
if(true === empty($gaza->champion)) {
return 'Invalid data received';
}
} else {
return 'No data found';
}
?>
您的比较条件似乎也存在语法错误，该错误使用赋值运算符，该运算符将始终求值为true。但不确定是否使用了您的代码部分。
elseif($getLeagueNamelistside =0){
应该只是
else {
将作为if ($getLeagueNamelistside <= 0) return DO_NOTHING;
<强>更新
要防止显示文件错误，并显示其他错误，您可以禁用错误消息的显示。无论如何，生产代码应该是这种情况。
ini_set('display_errors', 'off');
或过滤仅显示某些错误消息。
ini_set('error_reporting', E_ERROR | E_PARSE);
您还可以通过预先@
@file_get_contents('https://example.com/index.php');
最后但并非最不重要的，我的首选方法是使用输出缓冲来防止不需要的内容输出到客户端。
ob_start();
echo file_get_contents('https://example.com/index.php');
$content = ob_get_clean();
echo false === strpos($content, '404') ? $content : 'OOps';
