pg_field_size - Returns the internal storage size of the named field

SYNOPSIS

       int pg_field_size (resource  $result, int  $field_number)

DESCRIPTION

       pg_field_size(3) returns the internal storage size (in bytes) of the field number in the given PostgreSQL $result.

       Note

	       This function used to be called pg_fieldsize(3).

PARAMETERS

	      o $result
		- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).

	      o $field_number
		- Field number, starting from 0.

RETURN VALUES

	The internal field storage size (in bytes). -1 indicates a variable length field.  FALSE is returned on error.

EXAMPLES

       Example #1

	      Getting information about fields

	      <?php
		$dbconn = pg_connect("dbname=publisher") or die("Could not connect");

		$res = pg_query($dbconn, "select * from authors where author = 'Orwell'");
		$i = pg_num_fields($res);
		for ($j = 0; $j < $i; $j++) {
		    echo "column $j
";
		    $fieldname = pg_field_name($res, $j);
		    echo "fieldname: $fieldname
";
		    echo "printed length: " . pg_field_prtlen($res, $fieldname) . " characters
";
		    echo "storage length: " . pg_field_size($res, $j) . " bytes
";
		    echo "field type: " . pg_field_type($res, $j) . " 

";
		}
	      ?>

	      The above example will output:

	      storage length: -1 bytes
	      field type: varchar

	      fieldname: year
	      printed length: 4 characters
	      storage length: 2 bytes
	      field type: int2

	      column 2
	      fieldname: title
	      printed length: 24 characters
