php文件路径获取文件名

$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

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

$path_parts = pathinfo($file);

echo ‘目录名称‘ . $path_parts[‘dirname‘], ‘<br/>‘;  //  /www/htdocs/inc

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

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

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

echo ‘目录名称‘ . pathinfo($file, PATHINFO_DIRNAME), ‘<br/>‘;  //  /www/htdocs/inc

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

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

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