Hi I have just created a PR with the implementation of six new functions which can be used to manage suffixes and prefixes in strings. I did not actually plan to create the PR just yet, I just wanted to add the implementation as a sample of what I wanted to achieve and wanted to create the PR in my own fork but somehow I managed to actually create it in the main repo.
This is the PR https://github.com/php/php-src/pull/20953 Nevertheless, the idea is that in php code many times we have to deal with prefixes or suffixes of strings, this comes up a lot when you are dealing with file names or urls. Some examples - If the domain includes a initial www part, remove it - If the filename includes the .png extension, remove it - If the URL does not include the http:// schema, add it - If the URL is missing a trailing slash, add it - If the URL starts with http://, change it to https:// - If the filename ends in .jpeg, change it to .jpg - etc... It is not too difficult to implement this functionality by using the str_starts_with, str_ends_with and the substr functions or with preg_replace but I think it would be good to have some functions that can perform these operations in a single step, creating code which is simpler to write and to understand My proposal adds six functions: function add_prefix(string $source, string $prefix): string function add_suffix(string $source, string $suffix): string Add a prefix or suffix to a string *only if the string does not yet have it* function remove_prefix(string $source, string $prefix): string function remove_suffix(string $source, string $suffix): string Remove a prefix or suffix from a string if the string has it function replace_prefix(string $source, string $prefix, string $replace): string function replace_suffix(string $source, string $suffix, string $replace): string Replace a prefix or suffix in a string it the string has it I would like to know if the internals people think that the addition of these functions would be interesting. If there is some interest I will prepare a full RFC This is my first contribution to php-src so I would be grateful for any advice or hints :-) Cheers Carlos
