Question

所以我正在学习PHP，并从一些非常基础的东西开始。

我正在尝试从我的控制器文件夹中的文件调用一个函数，但它不起作用。

我已成功地将我输入的任何内容回显到URL栏中，但它不会在我的其他index.php文件中打印出作为控制器一部分的消息，但当然会继续回显任何消息输入的URL。我错过了什么吗？

所以这就是我坐在我的MVC文件夹之外的一个index.php文件：

<?php

$url = $_GET['url'];

echo $url;

require 'controllers/' . $url . '.php';
$controller = new $url;
?>

以下是我在我想要调用的controllers文件夹中的index.php文件中的内容：

<?php

class Index {

  function __construct(){
    echo 'We are in index';
  }
}

?>

我的.htaccess文件如下所示：

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l

RewriteRule ^(.*)$ /index.php?url=$1 [QSA,L]

如果您使用的是Linux，请将execute()更改为@interface LinksTableViewController (){ NSArray *data; } @property (strong, nonatomic) NSArray *links; @property (strong, nonatomic) NSArray *tNames; @property (strong, nonatomic) NSArray *dThor; @property (strong, nonatomic) NSArray *theLinker; @property (strong, nonatomic) NSArray *anText; @property (strong, nonatomic) NSArray *noDo; @end @implementation LinksTableViewController - (void)viewDidLoad { [super viewDidLoad]; UISegmentedControl *statFilter = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"STAT1", @"STAT2", @"STAT3", @"STAT4", nil]]; [statFilter sizeToFit]; [statFilter addTarget:self action:@selector(MySegmentControlAction:) forControlEvents: UIControlEventValueChanged]; self.navigationItem.titleView = statFilter; [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(refreshdelay:) userInfo:nil repeats:NO]; } - (void)MySegmentControlAction:(UISegmentedControl *)segment { NSArray *arrayToSort = data; if (segment.selectedSegmentIndex == 0) { NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"pda" ascending:NO]; arrayToSort = [arrayToSort sortedArrayUsingDescriptors:@[sortDescriptor]]; NSLog(@"%@", arrayToSort); } else if (segment.selectedSegmentIndex == 1) { } else if (segment.selectedSegmentIndex == 2) { } else if (segment.selectedSegmentIndex == 3) { } [self.tableView reloadData]; } -(void)refreshdelay:(NSTimer*)timer { NSString *myString = [links absoluteString]; NSURL *JSONData = [NSURL URLWithString:myString]; NSData *datas = [NSData dataWithContentsOfURL:JSONData]; NSURLRequest *request = [NSURLRequest requestWithURL:JSONData]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; operation.responseSerializer = [AFJSONResponseSerializer serializer]; operation.responseSerializer.acceptableContentTypes = [operation.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSArray *jsonResult = [NSJSONSerialization JSONObjectWithData:datas options:kNilOptions error:nil]; data = jsonResult; NSMutableArray *names = [NSMutableArray array]; NSMutableArray *bLinks = [NSMutableArray array]; NSMutableArray *daThor = [NSMutableArray array]; NSMutableArray *bsLink = [NSMutableArray array]; NSMutableArray *ancTxt = [NSMutableArray array]; NSMutableArray *folLowd = [NSMutableArray array]; for (id itemfeed in jsonResult){ [names addObject:[NSString stringWithFormat:@"%@", itemfeed[@"ut"]]]; [bsLink addObject:[NSString stringWithFormat:@"%@", itemfeed[@"uu"]]]; [bLinks addObject:[NSString stringWithFormat:@"%@", itemfeed[@"upa"]]]; [daThor addObject:[NSString stringWithFormat:@"%@", itemfeed[@"pda"]]]; [ancTxt addObject:[NSString stringWithFormat:@"%@", itemfeed[@"lt"]]]; [folLowd addObject:[NSString stringWithFormat:@"%@", itemfeed[@"lf"]]]; self.links = names; self.tNames = bLinks; self.dThor = daThor; self.theLinker = bsLink; self.anText = ancTxt; self.noDo = folLowd; } [self.tableView reloadData]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { }]; [operation start]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath]; static NSString *Cellidentifier = @"DataTableCellId"; LICustomCell *cell = (LICustomCell *) [tableView dequeueReusableCellWithIdentifier:Cellidentifier]; if (cell == nil) { cell = [[LICustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:Cellidentifier]; NSArray *nib = [[NSBundle mainBundle]loadNibNamed:@"LiCellView" owner:self options:nil]; cell = nib[0]; NSString *sLink = self.links[indexPath.row]; NSString *aLink = self.tNames[indexPath.row]; NSString *aDa = self.dThor[indexPath.row]; NSString *theInk = self.theLinker[indexPath.row]; NSString *thAnk = self.anText[indexPath.row]; NSString *fLink = self.noDo[indexPath.row]; cell.ageLable.text = theInk; } return cell; }，然后尝试使用小写字母访问索引。

无法从控制器调用index.php中的函数
