Yes - PHP arrays will inevitably be different to PostgreSQL arrays.

Hello,
Looks like it is best to forget about passing an array directly
between php and postgresql and instead rely on some string.
thanks to all

You could do something like:
(where $source_array is your array to pass to the PGSQL function):
<?php
// start off the query string
$query = "select func_a_dummy(";
// for each element of the array add to the string
foreach ($source_array AS $func_parameter)
{
$query .= "\"" . $func_parameter . "\", ";
}
// we'll end up with a trailing ", " on the end of the string due to the
final parameter, so remove it
$query = substring($query, 0, strlen($query) - 2);
// and close of the query string
$query .= ");";
?>
Then send $query to the database. That will create you something like
(if $source_array contains "param1" and "param2"):
select func_a_dummy("param1", "param2");
Regards,
Andy.
