pg_insert
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
pg_insert — Insert array into table
Description
$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 paramters/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_namemust at least have as many columns asassoc_arrayhas 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_ASYNCorPGSQL_DML_STRINGcombined. IfPGSQL_DML_STRINGis part of theoptionsthen query string is returned. WhenPGSQL_DML_NO_CONVorPGSQL_DML_ESCAPEis 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";
}
?>
