How to standardize the naming of photos in a folder in php? - php

Question

I have a folder containing several photos all in .jpg
The name they should all have is STYLE_COLOR-n.jpg for example K14700_7132-6.jpg because I made a script that deletes all the photos greater than -6.jpg.
My problem is that I have photos that are badly renamed, i.e. they have an underscore at the end instead of the dash like :
K14700_7132_6.jpg
Some also have a dash on both like this:
K14700-7132_6.jpg
And so my delete script doesn't work if the pictures don't all have the same rename...
Is it possible to automatically replace all the dashes and underscores that are bad to have this format on all my folder STYLE_COLOR-n.jpg?
<?php
$dir = 'C:/wamp64/www/divers/photos/';
$allFiles = scandir($dir);
foreach($allFiles as $file)
{
if (!in_array($file,array(".","..")))
{
$file = $dir.$file;
$filename = basename( $file ); //KA0710_7250-1.jpg
$underscore = explode("_", $filename);
// echo $underscore[0]."<br>"; //KA0710
$endstring = end($underscore);
// echo $endstring."<br>"; //7250-1.jpg
$underscore2 = explode("-", $endstring);
// echo $underscore2[1]."<br>"; //1.jpg
if ($underscore2[1] > 6)
{
unlink("$dir$filename");
echo 'File ' . $filename . ' has been deleted'."<br>";
}
else
{
}
}
}
echo "Deleted photos !";
?>

Sure, this is the part you'll add to that code:
$parts = preg_split("/[-_]+/", $filename);
$newfilename = strtoupper($parts[0].'_'.$parts[1]).'-'.$parts[2];
if ($newfilename !== $filename) {
rename($dir.$filename, $dir.$newfilename); // test this!
$filename = $newfilename;
}
Note - this will permanently rename files (that need it) so BEFORE you run this in production, please test for the old/new rename arguments just to be safe!
Here is the whole enchilada
<?php
$dir = 'C:/wamp64/www/divers/photos/';
$allFiles = scandir($dir);
foreach($allFiles as $file) {
if (!in_array($file,array(".",".."))) {
$file = $dir.$file;
$filename = basename( $file ); //KA0710_7250-1.jpg
// first fix the format
$parts = preg_split("/[-_]+/", $filename);
$newfilename = strtoupper($parts[0].'_'.$parts[1]).'-'.$parts[2];
if ($newfilename !== $filename) {
rename($dir.$filename, $dir.$newfilename); // test this!
$filename = $newfilename;
}
$underscore = explode("_", $filename);
$endstring = end($underscore);
// echo $endstring."<br>"; //7250-1.jpg
$underscore2 = explode("-", $endstring);
// echo $underscore2[1]."<br>"; //1.jpg
if ($underscore2[1] > 6) {
unlink("$dir$filename");
echo 'File ' . $filename . ' has been deleted'."<br>";
} else {
}
}
}
echo "Deleted photos !";
?>
