Question

我有两条路径需要剥离回Views文件夹，然后检查该文件夹中是否存在文件。

查看/ [控制器} / {操作} / {ID}

区/查看/ [控制器} / {操作} / {ID}

我正在寻找一种方法从网址中删除Views /

右边的所有内容

Answer 1

使用http://php.net/substr和http://php.net/function.strpos

的组合

$url = substr( $url, 0, strpos($url, "Views/"));

Answer 2

也许是这样的：

$url = 'Areas/Views/[Controller}/{Action}/{ID}';
$segmentedUrl = explode('/',$url);
$viewsPosition = array_search('Views', $segmentedUrl);
$leftPart = array_slice($segmentedUrl, 0, $viewsPosition+1);
var_dump($leftPart);

Answer 3

<?php

class Path{

    protected $originalPath;
    protected $path; // only this path gets manipulated for method chaining reasons

    public function setPath($path)
    {
        $this->originalPath = $path;
        $this->path = $path;
    }

    public function getPartial($partial)
    {
        if(!isset($this->originalPath))
            throw new Exception('No Path set');

        // Get the position of partial in our path
        $rawPos = strpos($this->path, $partial);
        if($rawPos === false)
        {
            throw new Exception('The Partial: '.$partial. 'was not found within the path');
        }
        else
        {
            // If we found the partial let's add the length of the given
            // string to figure the actual position 
            $pos = $rawPos + strlen($partial);
            $this->path = substr($this->path, 0, $pos);
            return $this;
        }
    }

    public function find($file)
    {
        $path = $this->path;
        $this->rewindPath();

        if(is_file($path . '/' . $file))
            return true;
        return false;
    }

    protected function rewindPath()
    {
        $this->path = $this->originalPath;
    }



}

// Instantiate Class
$path = new Path();

$path->setPath('Views/[Controller}/{Action}/{ID}');

var_dump($path->getPartial('Views')->find('test.txt'));

$path->setPath('Test/Views/[Controller}/{Action}/{ID}');

var_dump($path->getPartial('Views')->find('test.txt'));

尽管这个问题已经回答了，但我也希望向你展示一个OO方法。路径可以动态设置，您可以使用方法链接在那里搜索文件。这只是一个蓝图，所以你得到了基本的想法。

快乐的编码！
