In our study, many problems need to be solved continuously in practice. When we match PHP regular expressions, it is difficult to perform complex matching operations only by using regular table functions under POSIX. So how to implement multi-line matching of PHP regular expressions.
For example, perform a match search on the entire file (especially multi-line text). One way to do this using ereg() is to do it in separate lines. The example in Listing 6.5 demonstrates how ereg() assigns the parameters of the INI file to an array.

The above code example is the specific implementation method of PHP regular expression multi-line matching. I hope you can learn something after reading it. experience.
