当字符串包含数字时，Preg_replace不起作用

Question

So i have a string with flags like this: <<-- name -->> and now I want to replace all of them for ''.

I made the following function:

function removeFlags($output) {
    $output = preg_replace('/\<<--[^-->>]+-->>/', '', $output);
    return $output;
}

It works fine for the most flags but not when they contain numbers. For example: <<-- Model -->> will just be replaced for '', but <<-- 360 -->> will not be removed.

What am I doing wrong?

Answer 1

This should work for you, as you want to replace anything that is preceded and succeeded by a certain pattern

$output = preg_replace('/\<<--.+?-->>/', '', $output);

And I think your pattern should have worked for numbers as well, but do the numbers have a space before and after them?
