How to make the regular season more strict?

Question

JavaScript

Now with a similar regex:

preg_match("/update.[0-9]+.[a-z]+/", $input_line, $output_array);

The following passes: update/213/he/he/he
And according to the idea, only update/213/he
How to be?

Answer 1

Probably, instead of all the same, it should be
Object.keys(this.props.landingState).length > 0

Answer 2

You need to add markers for the beginning and end of the line. Like this:
Otherwise, the expression will work on any lines in which (in the middle of a long text, for example) there is the desired pattern.
Well, slashes must be explicitly specified.

Answer 3

Good afternoon.
Try doing this:

preg_match("#update\/[0-9]+\/[a-z]+#", $input_line, $output_array);
