回复讨论(解决方案)

$text = preg_replace_callback("/%u[0-9A-Za-z]{4}/", toUtf8, $str);
应为
$text = preg_replace_callback("/%u[0-9A-Za-z]{4}/", 'toUtf8', $str);

xuzuning大大， 'toUtf8'加两个单引号，我加了不行，我不知道是不是文件的编码有问题，本地测试的时候，有些Js文件我改一下编码，就显不了数据库的数据了

另外我直接输出结果

<?phpinclude_once ("connect.php");			$page = 1;	$limit = 12;	$sidx = 'id';		$sord = 'asc';		if (!$sidx)			$sidx = 1;        $where = '';        $title = "";        if(!empty($title))            $where .= " and title like '%".$title."%'";        $sn = "";        if(!empty($sn))            $where .= " and sn='$sn'";		$result = mysql_query("SELECT COUNT(*) AS count FROM products where deleted=0".$where);		$row = mysql_fetch_array($result, MYSQL_ASSOC);		$count = $row['count'];		//echo $count;		if ($count > 0) {			$total_pages = ceil($count / $limit);		} else {			$total_pages = 0;		}		if ($page > $total_pages)			$page = $total_pages;		$start = $limit * $page - $limit;		if ($start<0) $start = 0;		$SQL = "SELECT * FROM products WHERE deleted=0".$where." ORDER BY $sidx $sord LIMIT $start , $limit";		$result = mysql_query($SQL) or die("Couldn t execute query." . mysql_error());		$responce->page = $page;		$responce->total = $total_pages;		$responce->records = $count;		$i = 0;		while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {			$responce->rows[$i]['id'] = $row["id"];			$opt = "<a href='#'>修改</a>";			$responce->rows[$i]['cell'] = array ($row['sn'],$row['title'],$row['size'],	$row['os'],	$row['charge'],	$row['price'],$opt);			$i++;		}				echo json_encode($responce);?>

可以显示了，我把那些转换函数都删除了

Dependency 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 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.
