HomeBackend DevelopmentPHP Tutorialjson_encode之后,json数据变成[{"a","1"}],怎么改成{"a","1"}

function get_js_array($sql){	$result = mysql_query($sql);	$arr = array();	while($row = mysql_fetch_array($result, MYSQL_ASSOC)){		$arr[] = $row;  	}	$js = json_encode($arr);	mysql_free_result($result);	mysql_close($conn);	return $js;}


求根据这个改写一下。。 谢谢


回复讨论(解决方案)

$js = json_encode(array_pop($arr));

$js = json_encode(array_pop($arr));


是这样的。我那个输出出来希望是个{"a","1"},{"b","1"};

我现在这个方法输出出来是[{"a","1"},{"b","1"}]

你这个方法修改完了以后输出出来是{"a","1"}

括号去掉了。 但是只输出一条数据。

你的??是???的。

$js = trim(json_encode($arr), '[]');

你这个需求很奇怪,本来是数组,却不用数组表示

$js = trim(json_encode($arr), '[]');

是我给ios做后台接口。  json_encode 之后  传过去他们解析不了。 他们只能解析{"a","1"}... 加了[]  他们就解析不了了。。

谢谢了。  可以了。。

你??元素,不用??怎?行。
最??,你先json_encode,然後??掉??括?,但那?你如何decode?

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
