Postgresql regexp_matches inside view always returns null when queried from PHP

Question

I have view similar to this one

CREATE OR REPLACE VIEW regexp_test AS (
    SELECT regexp_matches(decode(\'NTB4\', \'base64\')::text, \'(\\d+)x\')
)
<         


        

Answer 1

pg_query returns a result resource.

$result = pg_query('SELECT * FROM regexp_test');

while ($row = pg_fetch_row($result)) {
  echo "$row";
}

pg_query returns false on error

If an error occurs, and FALSE is returned, details of the error can be retrieved using the pg_last_error() function if the connection is valid.
