pg_insert
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
pg_insert — Insert array into table
Description
pg_insert ( resource $connection , string $table_name , array $assoc_array [, int $options = PGSQL_DML_EXEC ] ) : mixed
pg_insert() inserts the values of assoc_array
into the table specified by table_name
. If options
is specified, pg_convert() is applied to assoc_array
with the specified options.
If options
is specified, pg_convert() is applied to assoc_array
with the specified flags.
By default pg_insert() passes raw values. Values must be escaped or PGSQL_DML_ESCAPE option must be specified. PGSQL_DML_ESCAPE quotes and escapes parameters/identifiers. Therefore, table/column names became case sensitive.
Note that neither escape nor prepared query can protect LIKE query, JSON, Array, Regex, etc. These parameters should be handled according to their contexts. i.e. Escape/validate values.
Parameters
-
connection
-
PostgreSQL database connection resource.
-
table_name
-
Name of the table into which to insert rows. The table
table_name
must at least have as many columns asassoc_array
has elements. -
assoc_array
-
An array whose keys are field names in the table
table_name
, and whose values are the values of those fields that are to be inserted. -
options
-
Any number of
PGSQL_CONV_OPTS
,PGSQL_DML_NO_CONV
,PGSQL_DML_ESCAPE
,PGSQL_DML_EXEC
,PGSQL_DML_ASYNC
orPGSQL_DML_STRING
combined. IfPGSQL_DML_STRING
is part of theoptions
then query string is returned. WhenPGSQL_DML_NO_CONV
orPGSQL_DML_ESCAPE
is set, it does not call pg_convert() internally.
Return Values
Returns the connection resource on success, or false
on failure. Returns string if PGSQL_DML_STRING
is passed via options
.
Examples
Example #1 pg_insert() example
<?php $dbconn = pg_connect('dbname=foo'); // This is safe somewhat, since all values are escaped. // However PostgreSQL supports JSON/Array. These are not // safe by neither escape nor prepared query. $res = pg_insert($dbconn, 'post_log', $_POST, PG_DML_ESCAPE); if ($res) { echo "POST data is successfully logged\n"; } else { echo "User must have sent wrong inputs\n"; } ?>
Changelog
Version | Description |
---|---|
5.6.0 | Unless PGSQL_DML_STRING is passed, the function now returns the connection resource instead of true on success. |
5.6.0 | No longer experimental. Added PGSQL_DML_ESCAPE constant, true /false and null data type support. |
5.5.3/5.4.19 | Direct SQL injection to table_name and Indirect SQL injection to identifiers are fixed. |
