String replace with wildcard

I have a string http://localhost:9000/category that I want to replace with category.html, i.e. strip everything before /category and add .html.

But can't find a way to do this with str_replace.

You want to use parse_url in this case:

$parts = parse_url($url);
$file  = $parts['path'].'.html';

Or something along that line. Experiment a bit with it.

Ismael Miguel suggested this shorter version, and I like it:

$file = parse_url($url,PHP_URL_PATH).'.html';

A solution without regex:

<?php
    $url = 'http://localhost:9000/category';
    echo @end(explode('/',$url)).'.html';
?>

This splits the string and gets the last part, and appends .html.

Note that this won't work if the input ends with / (e.g.: $url = 'http://localhost:9000/category/';)

Also note that this relies on non-standard behavior and can be easily changed, this was just made as a one-liner. You can make $parts=explode([...]); echo end($parts).'.html'; instead.

If the input ends with / occasionally, we can do like this, to avoid problems:

<?php
    $url = 'http://localhost:9000/category/';
    echo @end(explode('/',rtrim($url,'/'))).'.html';
?>

Use preg_replace instead of str_replace

Regex:

.*\/(.+)

Replacement string:

$1.html

DEMO

$input = "http://localhost:9000/category";
echo preg_replace("~.*/(.+)~", '$1.html', $input)

Output:

category.html
