How I could bulk Rename images based on regex with php? - php

Question

I want to remove this random string from my images names, but I can't figure out the right regex pattern to use.
Example file name: my-image-name-fbe49f24d64ad9432d6abede3dc9f0f9.jpg
Expected file name: my-image-name.jpg

Answer 1

if your string will always have the same format my-image-name-fbe49f24d64ad9432d6abede3dc9f0f9.jpg then you must do the following
$string = 'my-image-name-fbe49f24d64ad9432d6abede3dc9f0f9.jpg';
$sxplodePoint = explode('.', $string);
$ext = $sxplodePoint[count($sxplodePoint) - 1]; //obtanin extencion
$explodeGion = explode('-', $string);
$del = $explodeGion[count($explodeGion) -1];
$newString = '';
foreach ($explodeGion as $value) {
if($value != $del){
$newString = $newString. '-' . $value;
}
}
return trim($newString . '.' .$ext , '-');
A bit long code, but it will give the appropriate result if your string keeps that form
you can also use a function inside your controller
public function images(){
$stringImage = 'my-image-name-fbe49f24d64ad9432d6abede3dc9f0f9.jpg';
return $this->decodificator($stringImage);
}
public function decodificator($string){
$sxplodePoint = explode('.', $string);
$ext = $sxplodePoint[count($sxplodePoint) - 1]; //obtanin extencion
$explodeGion = explode('-', $string);
$del = $explodeGion[count($explodeGion) -1];
$newString = '';
foreach ($explodeGion as $value) {
if($value != $del){
$newString = $newString. '-' . $value;
}
}
return trim($newString . '.' .$ext , '-');
}
or also if its string is an array
public function imagesArray(){
$stringImages = [
'my-image-name-fbe49f24d64ad9432d6abede3dc9f0f9.jpg',
'my-image-name2-fbe49f24d64ad9432d6abede3dc9f0f9.jpg',
'my-image-name3-fbe49f24d64ad9432d6abede3dc9f0f9.jpg'
];
$newsStrings = [];
foreach($stringImages as $stringImage){
$newsStrings[] = $this->decodificator($stringImage);
}
return $newsStrings;
}
be careful in the shape of your string array, it may not necessarily be like my example
