Added rm_string in text_helper

[mmrtonmoybd]

Allows to removed specific keyword or fields from string.
I added a new function rm_string in text helper. It will removed specific keywords or fields from given string.
I am not good at English, so I did not give huge description about it.
Thank You All.

The initial issue was related to the validation, but it seems it can be solved with an existing rule.

please follow coding standard, you can run composer update and it will auto-fix in next commits when you make new changes.

I'm not really sure if this functionality fits as a helper function. Basically it's a one-liner in a loop... Also, why preg_replace() and not str_replace()?

Personally I'm not sold yet, but maybe you have some good use cases?

Other things:

• Code should comply with our code style
• We need tests
• We need updates to the user guide

[mmrtonmoybd]

@michalsn I changed the code. Maybe Now it is correct. Review it.

[samsonasik]

missing close }, also, again, please provide unit tests and follow coding style, do composer update and it will automatically fix it on next commit.

@samsonasik
I will fixed this problem soon, also give a unit test.
I close this pull request now, again reopen it soon.
This replace_string are helpful . when the developer didn't show some words/keywords in blog post /comment box.
Example : I want to push drugs in her body.
If I use this function the drugs will be replaced.
Output: I want to push in her body.

Soon I give a new PR .
Thanks to all Codeigniter Teams

I just realized that we have word_censor() function already. So this would be redundant functionality.

[mmrtonmoybd]

@michalsn Yes the function word_censor is same as my expected. I have not see this function at before.
Sorry for my mistake 😣😣😣.

Codeigniter have not route function in url helper, but codeigniter have site_url and base_url function.
In Laravel https://laravel.com/docs/7.x/helpers#method-route
Have route function .
This is very useful function in view when we working with form.
In Laravel we use like this

<form action="<?= route("blog.post") ?>">

If we didn't not assigned the url in router it's gives a exception.
Codeigniter also need a samilar helper function.
Maybe it will be added soon.

[michalsn]

No worries, I forgot about this too. I just remembered it because you gave me your use case example.

As for route thing. We have route_to() and url_to() functions:
