Using if/else operator in php code

Question

here's my question:

i have the folwing code in my project:

$news = "Article 20.part2";

if(strpos($news,'.part1')) {$news_n = ".part1";}
else if(strpos($news,'.part2')) {$news_n = ".part2";}
else if(strpos($news,'.part3')) {$news_n = ".part3";}
else if(strpos($news,'.part4')) {$news_n = ".part4";}
else if(strpos($news,'.part5')) {$news_n = ".part5";}

echo $news;
echo "Part number:" . $news_n . "- <a href=\"#\">Read more</a>";

What i want is to display the number of the news part, but the problem is that there are articles with +20/+30 parts and i don't want to add

else if(strpos($news,'.part20')) {$news_n = ".part20";}

etc to my code.

Is there any easier way to do this?

Thanks in advance for your help!

you can use PHP preg_match for this

$news = "Article 20.part20";
$matches= array();
if (preg_match("/\.part(\d*)/", $news,$matches)){
    $news_n = '.part'. $matches[1];
}

echo $news;
echo "Part number:" . $news_n . "- <a href=\"#\">Read more</a>";

Edit: You can also use $new_n = $matches[0];. $matches[0] gives you the full match and $matches[1] will have the number part.

Edit2: If the .part is the going to be the last item, then you can use much simpler strstr.

$news = "Article 20.part20";
$news_n = strstr($news, ".part");   
echo $news;
echo "Part number:" . $news_n . "- <a href=\"#\">Read more</a>";

This is the best solution, but maybe he need to think about loops before go to regexp

Maybe something like:

for($i=1;$i<100;$i++)
{
    if(strpos($news,'.part'.$i)) 
        $news_n = '.part'.$i;
}

Use a regular expression

$matches=[];
if (preg_match_all('.part\[( ^[0-9]{1,3}$)\]/', $news, $matches)) {
print_r($matches);
}

If the string you are looking for is numbered based as you say in your question you can do:

foreach(range(1, 50) as $i) {
    $part = sprintf('.part%d', $i);
    if(strpos($news, $part) {
        $news_n = sprintf('.%s', $part);
    }
}
