preg_match help

[devWhiz]

I fail miserably at regex

 

I need to get the string in between app# and &open

 

so it would be

 

$matches = "bz8D1qQq0rQHQ2WEQ5fGG3KIWNIFUqIhwwSRVlob%2b7bR7RH%3d";

 

 

app#bz8D1qQq0rQHQ2WEQ5fGG3KIWNIFUqIhwwSRVlob%2b7bR7RH%3d&open

 

and if someone could post a link to where I might be able to grasp the preg_match function, aside from the manual that would be great.. Thanks

To learn how to use this function you'll want to learn regular expressions. regular-expressions.info is good learning resource and http://gskinner.com/RegExr/ is a good site for testing out your regex patterns.

 

A regex pattern that you can use would be

preg_match('~app#(.*)&open~', $string, $matches);

 

preg_match will return an array of matches

Array
(
    [0] => app#bz8D1qQq0rQHQ2WEQ5fGG3KIWNIFUqIhwwSRVlob%2b7bR7RH%3d&open
    [1] => bz8D1qQq0rQHQ2WEQ5fGG3KIWNIFUqIhwwSRVlob%2b7bR7RH%3d
)

use $matches[1] to get the match string between the # and &. If you need to match multiple instances of app#{WHATEVER}&open then you'll need to use preg_match_all

I'd recommend changing .* to .*? in the above regex to stop it being a "greedy" regex
