Or I dont need to change anything on my swift code and I need to change my database to store emojis? Or my API PHP?
Your connection to MySQL must specify utf8mb4.
Your column/table must be `CHARACTER SET utf8mb4.

I want to store the whole Url of the image in my MySQL database coming from firebase storage when calling getDownloadUrl() method.
When doing the above I'm able to save the url but the token gets cut.
This is what I gets in my database
https://firebasestorage.googleapis.com/v0/b/vibesproject-b54f0.appspot.com/o/UserProfileImages/Shaks?alt=media
and when alerting the same url in the app I got the whole path as shown in the below figure.
How can I store the whole path with the token in the database
This is the App image
Check that the MySQL column length is not too short to store the whole URL.
Actually I would suggest using a column type of TEXT instead of VARCHAR.

I want to save chemistry equations in my database, equations for example:
`AB + O2 → Oxide of A & B`
Even typing here 2 is coming beside O whereas it's the symbol of oxygen like below:
Please note: If I am trying to directly copy and paste it in MySQL table field using phpMyAdmin, there also O2 is not getting saved as a symbol.
Note: MySQL field is text , collation is utf8mb4_general_ci.
Saving from php to mysql is next step. For now at least simply copying it (from phpMyAdmin) should work in MySQL.
I noticed that the subscript numbers on the web pages aren't actually subscripts, its just the HTML tag making it. (the <sub> tag).
So you have to use some kind of converter for it or do it yourself to convert it to actual unicode subscript.
If you want to print the equations to web page from database, you can save it with the HTML tag e.g.
H<sub>2</sub>O

I pass a variable called txt from one query on a web page to another web page using
<?php echo $_GET['txt'];?>
the problem some time the text will have a word like don't in it. the (') causes things to just stop. I need to output the variable as read from the database which would include any text that was in the field
When using $_GET you should use urlencode() and urldecode().

You can use htmlentities or use single quote '', this is a very good SO question and answer on difference in php between single and double quotes.
Use htmlentities($your_html_code);
It is your safest bet, it does what htmlspecialchars() does, and more.
