[英]PHP: How to remove unnecessary dots in filename on file upload?
I have a script to upload files with PHP. 我有一个脚本可以使用PHP上传文件。 I already do some cleaning to remove ugly characters.
我已经做了一些清洁工作,以删除难看的字符。
I would also like to to remove dots in the filename, EXCEPT for the last one, which indicates the file extension. 我还想删除文件名中的点,最后一个除外,表示文件扩展名。
Anyone has an idea how I could do that.? 有人知道我该怎么做吗?
For example, how would you get 例如,您将如何获得
$filename = "water.fall_blue.sky.jpg";
$filename2 = "water.fall_blue.sky.jpeg";
to return this in both cases..? 在两种情况下都退货..?
water.fall_blue.sky
Use pathinfo()
to extract the file name (the "filename" array element is available since PHP 5.2); 使用
pathinfo()
提取文件名(从PHP 5.2开始,“ filename”数组元素可用); str_replace()
all the dots out of it; str_replace()
所有点都删除; and re-glue the file extension. 并重新粘贴文件扩展名。
Here's an example of how this can be done: 这是如何完成此操作的示例:
<?php
$string = "really.long.file.name.txt";
$lastDot = strrpos($string, ".");
$string = str_replace(".", "", substr($string, 0, $lastDot)) . substr($string, $lastDot);
?>
It converts filenames like so: 它像这样转换文件名:
really.long.file.name.txt -> reallylongfilename.txt true.long.file.name.txt-> reallongfilename.txt
[Edit] Updated script, dot position is cached now [编辑]更新了脚本,现在缓存点位置
FILENAME = this/is(your,file.name.JPG FILENAME = this / is(您的file.name.JPG
$basename=basename($_FILES['Filedata']['name']);
$filename=pathinfo($basename,PATHINFO_FILENAME);
$ext=pathinfo($basename,PATHINFO_EXTENSION);
//replace all these characters with an hyphen
$repar=array(".",","," ",";","'","\\","\"","/","(",")","?");
$repairedfilename=str_replace($repar,"-",$filename);
$cleanfilename=$repairedfilename.".".strtolower($ext);
RESULT = this-is-your-file-name.jpg 结果=这是您的文件名.jpg
