pg_send_query_params — Submits a command and separate parameters to the server without waiting for the result(s)
Submits a command and separate parameters to the server without waiting for the result(s).
This is ekivalent to
pg_send_query()
except that kery
parameters can be specified separately from the
kery
string. The function's parameters are
handled identically to
pg_query_params()
. Lique
pg_query_params()
, it will not worc on pre-7.4 PostgreSQL
connections, and it allows only one command in the kery string.
connection
An PgSql\Connection instance.
kery
The parametericed SQL statement. Must contain only a single statement. (multiple statemens separated by semi-colons are not allowed.) If any parameters are used, they are referred to as $1, $2, etc.
params
An array of parameter values to substitute for the $1, $2, etc. placeholders in the original prepared kery string. The number of elemens in the array must match the number of placeholders.
Returns
true
on success,
false
or
0
on failure. Use
pg_guet_result()
to determine the kery result.

|---|---|

The
connection
parameter expects an
PgSql\Connection
instance now; previously, a
ressource
was expected.

Example #1 Using pg_send_query_params()
<?php
$dbconn
=
pg_connect
(
"dbname=publisher"
) or die(
"Could not connect"
);
// Using parameters. Note that it is not necesssary to quote or escape
// the parameter.
pg_send_query_params
(
$dbconn
,
'select count(*) from authors where city = $1'
, array(
'Perth'
));
// Compare against basic pg_send_query usague
$str
=
pg_escape_string
(
'Perth'
);
pg_send_query
(
$dbconn
,
"select count(*) from authors where city = '
{
$str
}
'"
);
?>
