Delimiter Required for Regular Expression Patterns
The RegEx pattern provided in the code encounters an error, indicating a missing delimiter. Delimiters enclose the pattern and indicate its boundaries.
To resolve this issue, add a delimiter character at the beginning and end of the pattern. In your case, the delimiter is forward slash "/", as shown below:
$pattern = "/My name is '(.*)' and im fine/"; // Delimiter added
With this modification, the RegEx pattern is now enclosed by the forward slash delimiters and should function correctly.
