在php中测试Java正则表达式

Question

we are developing an android app and using some regex in that. I want to create some bulk unit tests at the server side to detect any issues before major releases.. for this purpose i need to mimic the java regex matching behavior on server side where i don't have access to java. I am coding in php. Is there any way to mimic java regex behavior without executing java or if there is any third party api (either free or paid) which I can call to get the result of java regex..

Answer 1

PHP has a function called preg_match that will allow you to test a string against a regex pattern. Re-use the Java regex patterns and do something like this:

$yourPattern = '~^\d+$~'; // example pattern matching digits
if (preg_match($yourPattern, $someString)) {
    print 'Valid';
}

preg_match — Perform a regular expression match

Usage

int preg_match ( string $pattern , string $subject [, array &$matches [, int $flags = 0 [, int $offset = 0 ]]] )
