Issue

I'm trying to figure out a regex to express this string:

 dev_XXX_<name>

where XXX is a 3 digit number and name is already expressed with /[0-9a-zA-Z \- _]/.

This regular expression will be used as a model validation rule in PHP/YII, so it's a PCRE regular expression.

My non-working solution is this one:

/^dev_([0-9]{3})_<([0-9a-zA-Z \- _])>*$/

But it seems to not accept the last major sign.

Thank you for any help & explanations!

Solution

Looks like your asterisk is in the wrong place

/^dev_([0-9]{3})_<([0-9a-zA-Z \- _])>*$/

should be

/^dev_([0-9]{3})_<([0-9a-zA-Z \- _]*)>$/

This will mean that your character set [0-9a-zA-Z \- _] should match zero or more of those characters
