接收端是print_r($_POST);
发送端写了一个curl提交post。
$ch = curl_init(); curl_setopt_array($ch, array( CURLOPT_URL => 'http://myurl/abc.php', CURLOPT_RETURNTRANSFER => true, CURLOPT_POST => true, CURLOPT_POSTFIELDS =>'name=abc&id=123' ) ); $content = curl_exec($ch); print_r($content); echo '<br>=========<br>'; echo $content['name'];
打印出来的结果:
Array( [name] => abc [id] => 123 ) ========= A
为什么$content['name']得到的是一个字母A...
回复内容:

$ch = curl_init(); curl_setopt_array($ch, array( CURLOPT_URL => 'http://myurl/abc.php', CURLOPT_RETURNTRANSFER => true, CURLOPT_POST => true, CURLOPT_POSTFIELDS =>'name=abc&id=123' ) ); $content = curl_exec($ch); print_r($content); echo '<br>=========<br>'; echo $content['name'];

$content = curl_exec($ch);
这行代码拿到的 $content 是一个字符串。所以你在 echo 的时候打印的是这个字符串。
把print_r换成 var_dump 就一目了然了
var_dump($content);
得到结果:
string(44) "Array ( [name] => abc [id] => 123 ) "
echo $content['name']; // 这一句
$content是一个字符串, 'name'在这里被转乘整数0,所以是第一个字母A.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
