删除具有特殊字符和数字的特定字符串

I have following example its working fine but i want to remove Issue No1 – ,Issue No2 – ,Issue No3..... at once because I don't want to add Issue No2 – , Issue No3 ... everytime in preg_replace. I think this is possible with preg_replace. I wrote following code but did not get the actual result. Any advise or guidance would be greatly appreciated.

$catName="Issue No1 – This is new Issue No2 – This is also new item Issue No3 – This is new one There are 1 2 3 items ....... ";
echo $catName= preg_replace("/Issue No\d+/","",$catName);

Output should be:

This is new This is also new item This is new one There are 1 2 3 items .......

You also have to add - at end of your expression

preg_replace("/Issue No\d+ –/", "", $catName);

DEMO

Try like below -

$catName = preg_replace("(Issue No[0-9]+)", "", $catName);

<?php
    $catName="Issue No1 - This is new Issue No2 - This is also new item Issue No3 - This is new one There are 1 2 3 items ....... ";
    echo "<h1>$catName</h1>
";

    $catName = preg_replace("/Issue No\d+ - /","",$catName);
    echo "<h1>$catName</h1>
";

?>
