Re: RV: calling a pl/pgsql function with array in argument

this is a little bit hidden information somewhere in the manual.
Array types is the same the corresponding data type but
prepended with an underscore '_', e.g:

_int4
_date
_smallint

btw, you cannot pass PHP array to plpgsql function. You need to
convert it to string like:

{1,2,23,45}

{ -- start array
,, -- comma separated values
} -- closing tag

here is my quote function to PG:

function quote($var, $type, $empty_null = TRUE)
{
if ( empty($var) && $empty_null ){
return 'NULL';
}
if ( $type{0} == '_' ){
$type = substr($type, 1);
$temp = "'{";
foreach ( $var as $item ){
$temp .= quote($item, $type).',';
}
$temp = substr($temp, 0, -1);
return $temp ."}'";
}
switch ( $type ){
case 'int':
return intval($var);
case 'bool':
return ($var ? "'t'::bool": "'f'::bool");
case 'date':
if ( is_numeric($var) ) { // echo timestamp-kent kezeli
return date("'Y-m-d'", $var);
}
// ha ez sem, akkor sima szovegkent tovabbadja
case 'text':
if (!get_magic_quotes_gpc()) {
$var = addslashes($var);
}
return '\''.$var.'\'';
default: trigger_error("unknown type : $type ($value)", E_USER_ERROR);
}
}
