For a small history oriented project I am looking to convert an identifier (used for links) to an appealing title. Below are five examples of how the identifiers might be called and how I am trying to make them look. However, I can't figure it out unfortunately.
Is there an elegant solution for something like this in PHP?
[identifier] = [title]
This should work for you:
Just use preg_replace_callback() to bring your string in your expected format, e.g.
<?php
$str = "1904-1905-france-germany";
echo $str = preg_replace_callback("/(\d+)(?:-(\d+))?(.*)/", function($m){
if(!empty($m[2]))
return $m[1] . "/" . substr($m[2], -2) . implode(" ", str_replace("-", " ", array_map("ucfirst", explode("-", $m[3]))));
return $m[1];
}, $str);
?>
output:
1904/05 France Germany
Getting all elements into an array, and filtering and formatting result by array element counts works too:
$subject2 = '1904-1905-france-germany-spain';
$new = explode('-', $subject2);
if(count($new) == 2){
echo $name = $new[0] . '/' . substr($new[1], 2);
} elseif (count($new) > 2) {
$name = $new[0] . '/' . substr($new[1], 2);
for($i = 2; $i<count($new); $i++ ){
$name.= ' ' . ucfirst($new[$i]) . ' ';
}
$name = trim($name, ' ');
echo $name;
}
