php获取文件名的方法:可以用basename()函数来获取文件名,例如:【basename($full_name)】。还可以使用pathinfo()函数来获取文件名。

php如何获取文件名

PHP中获取文件名的方式

1、直接用basename:

<?php
$full_name = &#39;c:\wamp\php\php.ini&#39;;
$base = basename($full_name); // $base is "php.ini"
$dir = dirname($full_name);  // $dir is "c:\wamp\php"
?>

2、pathinfo:

<?php
$path_parts = pathinfo(&#39;/www/htdocs/inc/lib.inc.php&#39;);
 
echo $path_parts[&#39;dirname&#39;], "\n";
echo $path_parts[&#39;basename&#39;], "\n";
echo $path_parts[&#39;extension&#39;], "\n";
echo $path_parts[&#39;filename&#39;], "\n"; // since PHP 5.2.0
?>

3、explode :使用一个字符串分割另一个字符串

array explode ( string $delimiter , string $string [, int $limit ] )
