PHP：提取目录中文件的所有文件名的各个部分

Question

I'd like to be able to loop over all of the files within a directory (the one the script is in) and extract portions of the name and turn it into CSV readable.

From:

ch-026-Metallic-Morphing Mauve-14pt.jpg

To:

ch-026, Metallica-Morphing Mauve-14pt

...or however Excel or Numbers would be able to read it.

At the request of a couple of you, I'll clarify that I want to cut out the second "-" dash and replace it with a comma and space.

Answer 1

First, use

$fileList = scandir( $directoryPath );

to scan the directory. Then loop like this

foreach( $fileList as $fileName ) {
 ...
}

Finally, use preg_match to match entries. Generally:

$subject = "abcdef";
$pattern = '/^def/';
preg_match($pattern, fileName, $matches, PREG_OFFSET_CAPTURE);
print_r($matches);

In your case a pattern like

$pattern = '/^ch-\d*-(.*)-\d*pt\.jpg$/';

might do the job.

Finally, use the information provided in $matches to write the CSV file.
