如果你想包含所有在一个目录和它的子目录:

$dir = "classes/";
$dh  = opendir($dir);
$dir_list = array($dir);
while (false !== ($filename = readdir($dh))) {
    if($filename!="."&&$filename!=".."&&is_dir($dir.$filename))
        array_push($dir_list, $dir.$filename."/");
}
foreach ($dir_list as $dir) {
    foreach (glob($dir."*.php") as $filename)
        require_once $filename;
}

不要忘记，它将使用字母顺序来包括您的文件。

你可以使用set_include_path:

set_include_path('classes/');

http://php.net/manual/en/function.set-include-path.php

2017年如何做到这一点:

spl_autoload_register( function ($class_name) {
    $CLASSES_DIR = __DIR__ . DIRECTORY_SEPARATOR . 'classes' . DIRECTORY_SEPARATOR;  // or whatever your directory is
    $file = $CLASSES_DIR . $class_name . '.php';
    if( file_exists( $file ) ) include $file;  // only include if file exists, otherwise we might enter some conflicts with other pieces of code which are also using the spl_autoload_register function
} );

这里由PHP文档推荐:自动加载类

如果文件之间没有依赖关系…下面是一个递归函数来包含所有子dirs中的include_once所有php文件:

$paths = array();

function include_recursive( $path, $debug=false){
  foreach( glob( "$path/*") as $filename){        
    if( strpos( $filename, '.php') !== FALSE){ 
       # php files:
       include_once $filename;
       if( $debug) echo "<!-- included: $filename -->\n";
    } else { # dirs
       $paths[] = $filename; 
    }
  }
  # Time to process the dirs:
  for( $i=count($paths)-1; $i>0; $i--){
    $path = $paths[$i];
    unset( $paths[$i]);
    include_recursive( $path);
  }
}

include_recursive( "tree_to_include");
# or... to view debug in page source:
include_recursive( "tree_to_include", 'debug');

如果你想包含所有在一个目录和它的子目录:

$dir = "classes/";
$dh  = opendir($dir);
$dir_list = array($dir);
while (false !== ($filename = readdir($dh))) {
    if($filename!="."&&$filename!=".."&&is_dir($dir.$filename))
        array_push($dir_list, $dir.$filename."/");
}
foreach ($dir_list as $dir) {
    foreach (glob($dir."*.php") as $filename)
        require_once $filename;
}

不要忘记，它将使用字母顺序来包括您的文件。

尝试使用库来实现这个目的。

这是我构建的相同想法的一个简单实现。 它包括指定的目录和子目录文件。

IncludeAll

通过终端[cmd]安装

composer install php_modules/include-all

或者将其设置为包中的依赖项。json文件

{
  "require": {
    "php_modules/include-all": "^1.0.5"
  }
}

使用

$includeAll = requires ('include-all');

$includeAll->includeAll ('./path/to/directory');
