pg_insert
(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)
pg_insert — Insert array into table
Description
PgSql\Connection
$connection,string
$table_name,array
$values,int
$flags = PGSQL_DML_EXEC): PgSql\Result|string|bool
pg_insert() inserts the values
of values into the table specified
by table_name.
If flags is specified,
pg_convert() is applied to
values with the specified flags.
By default pg_insert() passes raw values.
Values must be escaped or the PGSQL_DML_ESCAPE flag
must be specified in flags.
PGSQL_DML_ESCAPE quotes and escapes parameters/identifiers.
Therefore, table/column names become 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 -
An PgSql\Connection instance.
-
table_name -
Name of the table into which to insert rows. The table
table_namemust at least have as many columns asvalueshas elements. -
values -
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. -
flags -
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 theflagsthen query string is returned. WhenPGSQL_DML_NO_CONVorPGSQL_DML_ESCAPEis set, it does not call pg_convert() internally.
Return Values
Returns true on success or false on failure.. Or returns a string on success if PGSQL_DML_STRING is passed
via flags.

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";
}
?>
