物理截取：

$file = ‘/www/htdocs/inc/lib.inc.php‘;

$filename = basename($file);

echo $filename, ‘<br/>‘;//  lib.inc.php

$filename = str_replace(strrchr($filename, ‘.‘), ‘‘, $filename);

echo $filename, ‘<br/>‘;//  lib.inc

使用pathinfo($path, $options)：

$file = ‘/www/htdocs/inc/lib.inc.php‘;

$path_parts
 
 = pathinfo($file);

echo ‘目錄名稱‘ . $path_parts[‘dirname‘], ‘<br/>‘;  //  /www/htdocs/inc

echo ‘文件全名‘ . $path_parts[‘basename‘], ‘<br/>‘; //  lib.inc.php

echo ‘文件後綴‘ . $path_parts[‘extension‘], ‘<br/>‘;//  php

echo ‘文件名稱‘ . $path_parts[‘filename‘], ‘<br/>‘; //  lib.inc         // PHP >= 5.2.0
 


echo ‘目錄名稱‘ . pathinfo($file, PATHINFO_DIRNAME), ‘<br/>‘;  //  /www/htdocs/inc

echo ‘文件全名‘ . pathinfo($file, PATHINFO_BASENAME), ‘<br/>‘; //  lib.inc.php

echo ‘文件後綴‘ . pathinfo($file, PATHINFO_EXTENSION), ‘<br/>‘;//  php

echo ‘文件名稱‘ . pathinfo($file, PATHINFO_FILENAME), ‘<br/>‘; //  lib.inc         // PHP >= 5.2.0
