PHP-String remove everything before and including " – " – Woocommerce

In WooCommerce I can get the variaation name with:

$variation_obj = wc_get_product($variation['variation_id']);                                    
variation_name = $variation_obj->get_name();

This gives me an output with the following pattern: ” – ” but I just need the Variation attribute output. Examples are:
“Refresh Spray – 250 ml”
“Refresh Spray – 500 ml”
“Refresh Spray – 1 l”

How can I remove the ” – ” and everything in front of it?

    There are various different methods for doing this kind of thing but my trick is the code below.

    <?php

$var = "blahblahblah - hello"; // put here your variable containing the "-"
$var = explode("-", $var); // cuts the string into pieces at the "-" and removes the "-"
$var = $var[0]; // grabs the part before the "-"
$var = $var."-"; // adds the "-" again, remove this part if you don't want the "-"

echo($var);

?>

    this should do exactly what you want.

    You can search for the last occurrence and get the string after that:

    $name = substr($variation_name, strrpos($variation_name, '-'));

    and when you want to remove any whitespaces use trim afterwards:

    $name = trim($name);

    If you want to remove everything before “-” including it: 

    $str_after = preg_replace("#.+s?-#","",$variation_name);

    But if you want to remove everything after including the “-“:

    $str_before = preg_replace("#-s?.+#","",$variation_name);
