pg_field_prtlen
PG_FIELD_PRTLEN(3)PG_FIELD_PRTLEN(3)pg_field_prtlen - Returns the printed lengthSYNOPSIS
int pg_field_prtlen (resource $result, int $row_number, mixed $field_name_or_number)
DESCRIPTION
int pg_field_prtlen (resource $result, mixed $field_name_or_number)
pg_field_prtlen(3) returns the actual printed length (number of characters) of a specific value in a PostgreSQL $result. Row numbering
starts at 0. This function will return FALSE on an error.
$field_name_or_number can be passed either as an integer or as a string. If it is passed as an integer, PHP recognises it as the field num-
ber, otherwise as field name.
See the example given at the pg_field_name(3) page.
Note
This function used to be called pg_fieldprtlen(3).
PARAMETERS
o $result
- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).
o $row
- Row number in result. Rows are numbered from 0 upwards. If omitted, current row is fetched.
RETURN VALUES
The field printed length, or FALSE 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:
column 0
fieldname: author
printed length: 6 characters
storage length: -1 bytes
field type: varchar
column 1
fieldname: year
printed length: 4 characters
storage length: 2 bytes
field type: int2
column 2
fieldname: title
printed length: 24 characters
storage length: -1 bytes
field type: varchar
