Regular expressions in PHP are powerful tools for pattern matching and manipulating strings.
Regular expressions are defined using the preg_match() function in PHP.
They are used to search, replace, and validate strings based on specific patterns.
Regex patterns consist of a combination of characters and special symbols.
Modifiers can be added to the pattern to control the matching behavior.
Common regex functions in PHP in...
