Regex to optimize code change using Notepad++

Question

Hello, can someone please help me create a regex expression for the pattern below.

I have in my php code the following pattern: htmlspecialchars($str) I need to create an expression that replaces that for this: htmlspecialchars($str,ENT_NOQUOTES,"UTF-8")

The expression must recognize the size of $str and ignore it. After all, I hope that texts like the below have added to their end, the string: ENT_NOQUOTE,"UTF-8.

For example: Where I have:

htmlspecialchars($table->content)

should stay that way:

htmlspecialchars($table->content,ENT_NOQUOTES,"UTF-8") 

Where I have:

htmlspecialchars($_POST['title'])

should stay that way:

htmlspecialchars($_POST['title'],ENT_NOQUOTES,"UTF-8")

Squeeze Ctrl+H and in the field Find what add this:

htmlspecialchars\(([^,]+?)\)

And in the field Replace with this:

htmlspecialchars\($1, ENT_NOQUOTES, "UTF-8"\)

See the example on Notepad++:

Explaining the regex:

• The \( and the \) is to escape the parentheses that in regex are used for groups, this way will not be used so, will be as normal quotes.

• The ([^,]+?) forms a group that searches for everything that does not have a comma, so it will avoid substituting in places where the string is already correct (htmlspecialchars($str,ENT_NOQUOTES,"UTF-8"))

• the $1 in the field Replace with (htmlspecialchars\($1, ENT_NOQUOTES, "UTF-8"\)) serves to take the value of the group ([^,]+?) at the time of replace.
