phpmaster | Using PHP Regular Expressions

Core points Regular expressions (also known as regex) are patterns used to match text in strings. They are especially useful when you need to find text for different instances in a string.

PHP uses functions such as preg_match(), preg_replace(), and preg_match_all() to apply regular expressions. These functions can verify form fields, format text, and extract information arrays from strings, respectively. Metacharacter, quantifier and fraction
