I have a php 7 app and I want to match some patterns using regex. I have the following pattern so far:
/=\~|=\*|=|!=|\(\)|>=|<=|>|</
And I'm able to match any of the following:
=~, =*,=,!=...etc.
However, I want to match two more patterns, the first starts with = followed by any number of chars (including numbers and special characters) ending with an asterisk, for example: =ijnhu9* or =1$n*. The second one is = followed by an asterisk followed by any number of chars (including numbers and special characters). For example: =*bfrg%1 or =*7lk;y. How can I add these two new patterns to my original pattern? Thank you.

You can extend the alternation with the parts that you want, and put the most specific ones at the beginning.
=\*[^\s*=]*|=[^\s*=]*\*|=[~*]?|!=|\(\)|[<>]=?
