Hello I have used this wp function kd_mfi_get_featured_image_id that is deprecated. But in error log actually I have a big amount of rows due to this function and I think that affect on performances too.
It is also used by my theme that is one of the most used (Avada).
So I wanna ask you an alternative for this one.
The kd_mfi_get_featured_image_id function has been deprecated since
Avada 5.2.0. Please use fusion_get_featured_image_id instead.
Taken from here

Hide deprecated warning
Does anyone know if there is any way to hide warning for a specified deprecated class (not all warning) in VS Code?
I am using VS Code Version: 1.55.2 (Universal) and PHP IntelliSense v2.3.14
From (https://code.visualstudio.com/updates/v1_49):
Disable these strike throughs by setting "editor.showDeprecated":
false
See also here: https://github.com/microsoft/TypeScript/issues/40511
The word 'super' then gets striked through and hovering over seems to
say it is deprecated for typescript, but this is not a typescript
file. It does not affect the code but is confusing many people.
Working around it by disabling the "Editor: Show Deprecated" setting,
but would prefer to be able to enable that setting. This has only been
happening since the VS Code update on August 10, 2020 (yesterday).
I've found the following code that checks if the stripslashes() function exists.
if ( function_exists( 'stripslashes' ) ) {
// Do something
} else {
// Do something
}
The stripslashes() function works on PHP4 and PHP5, so I wonder why it needs a conditional statement to check if the function exists. I don't get it.
It's not a subjective question. Just tell me what is the difference between the usage of this statement and not using it. Thanks in advance!

There used to be a feature in PHP known as magic quotes, which while well-intentioned, has caused endless confusion.
Most likely this code is intended to detect magic quotes, however this is not the correct way to do this, especially since it does not work.
The correct way to detect if magic quotes are enabled is to use the fuction made for the purpoes, get_magic_quotes_gpc like so.
if (get_magic_quotes_gpc()) {
Or perhaps the following, if you are concerned this will be removed.
if (function_exists('get_magic_quotes_gpc') && get_magic_quotes_gpc()) {
That being said, the whole magic quotes feature was removed back in PHP 5.4, so unless you need to support obsolete versions of PHP, you can just forget the whole thing ever existed (unless you use WordPress that is...).
On a side note, I suppose it's possible the stripslashes function may be removed in the future, and may not have existed at one point, but in this context that's probably not the reason.
Sidenote: Transcribed from some of my comments (slightly modified) to supply the question with a complimentary answer to that of Alexander's.
This is probably to check if some coder went and created a custom function called the same (a method to someone's madness?), or somebody hacked the PHP core and removed it; I'm speculating of course, it's not impossible.
However, the same thing goes for if ( function_exists( 'mysql_real_escape_string' ) ).
If a server doesn't support those old and deprecated mysql_ functions, then the conditional statement is needed and would prove to be effective/useful for something of that nature to be used.

https://wiki.php.net/rfc/mysql_deprecation
https://wiki.php.net/rfc/remove_deprecated_functionality_in_php7
https://wiki.php.net/rfc
Personally, function_exists() should only be used against probable deprecated functions; mysql_ being one of them and session_register() - I'm sure there are more.
It's listed in the manual from contributed notes http://php.net/manual/en/function.stripslashes.php and it seems to have something to do with magic_quotes_gpc as per what Alexander (O'Mara) said in comments.
N.B.:
I am by no means looking to gain anything from this, but for others visiting the question.
Is it possible to add a removed/deprecated function to PHP5? Like session_is_registered, ereg, etc.
[update] solved for session_is_registered:
<?php
function session_is_registered($name) {
return isset($_SESSION[$name]);
}
thanks.
Of course you can do it by modifying and recompiling the PHP source code, however the first question you have to answer is Do I really need to this or I might be better to go for my IDE's find-and-replace function?
If there is a real need for this -- for whatever reason, maybe you can redefine those functions. I haven't test it yet, as I agree with others that functions and features get removed or deprecated for a good and mostly important reasons, so I'm not sure if it does work in a situation that the function is removed or depreciated, but you can try to redefine them either using runkit_function_redefine or
override_function.
In that case you have to simulate the functionality again -- probably with their good-to-go replacements, so again think twice before start doing that.
Is there a way to remove function alias in PHP?
I can rename my function but it would be nice to use name "fetch".
Problem:
I just tested the following code and it appears to work for me, but perhaps it is because I don't have the mysqli library installed. I would test it because it might be more contextual than your IDE will have you believe. It seems to be a method for mysqli, but it might not be a global function.
<?php
function fetch(){
echo 'Hello world!';
}
fetch();
No.
(Short of recompiling the PHP binary)
This is more of a function of the IDE than the actual language... Some IDEs may give you that ability... I don't even know if recompiling the PHP binary (as Alan Storm suggested) would help since sometimes the stuff is hardcoded into the IDE / use the PHP docs online
For completeness sake: Normally, no, this can not be done. However: this can be done using a PECL extension called "runkit".
Runkit is described as "For all those things you probably shouldn't have been doing anyway", and allows you to basically tear out the innards of PHP from within PHP itself. Replacing built-in functions, undefining constants, unloading classes - suddenly everything is possible. And you should really question what you are doing if you ever feel you need it - odds are what you are doing violates some principles that are there for very good reasons, you just don't know them yet. I've never found a situation where using Runkit was a genuinely Good Idea.
Oh, in order to remove built-in functions you'll specifically need to enable this capability in your php.ini

I'm new in this site. I want to ask about PHP programming. How do we can handle deprecated function in PHP. I want to redirect it to my new function. As we know, ereg function has been deprecated in PHP 5.3.0 and recommended to preg_match (posix to PCRE). But, when we wrote a lot of code with ereg function, do we have to change it manually? I want a solution like this.
function ereg($pattern, $string, &$array) { return preg_match('#'.$pattern.'#', $string, $array); }
The main problem is not the ereg function, but solution of handling deprecated function.
I've been searching in Google. Someone suggest to use override_function (using APD extension). But, this extension is hard to find (I need precompiled extension build for windows). Anyone can help me?
I'm sorry for my bad English. I hope you can understand.
The reason they tell you it is deprecated, and they don't remove it completely, is to give you time to update your code.
If you don't want to update your code, you can always just not upgrade your install of PHP. Or you can wait until a release of PHP is out were ereg() is removed completely, and use your above solution.
Other possible solutions include doing a search/replace for all ereg calls, and replacing it my_ereg, which could be the function you defined above.
Also:
if(!function_exists("ereg")){ .... }
Define the function inside of the if statement that checks if the function already exists. This will make the transition smoother.
But all in all, the purpose of deprecation is to give developers time to update their code and stop using all of the deprecated functions before they remove it completely from the code base.
I believe some call it 'Maintenance'.
You could always use the function_exists function.
if(!function_exists('ereg'))
{
function ereg($pattern, $string, &$array)
{
return preg_match('#'.$pattern.'#', $string, $array);
}
}
Using this method would allow it to work in all version as if it is deprecated but still able to be used it will use the function but once it has been removed from php it will be able to use your user defined function.
