pg_insert — Insert array into table
$connection
,$table_name
,$values
,$flags
= PGSQL_DML_EXEC
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.
connection
An PgSql\Connection instance.
table_name
Name of the table into which to insert rows. The table table_name
must at least have as many columns as values
has 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_ASYNC
or PGSQL_DML_STRING
combined. If PGSQL_DML_STRING
is part of the flags
then query string is returned. When PGSQL_DML_NO_CONV
or PGSQL_DML_ESCAPE
is set, it does not call pg_convert() internally.
Returns true
on success or false
on failure.. Or returns a string on success if PGSQL_DML_STRING
is passed via flags
.
A ValueError is thrown when the specified table is invalid.
A ValueError or TypeError is thrown when the value or type of field does not match properly with a PostgreSQL's type.

<?php
$dbconn = pg_connect('dbname=foo');
// This is safe somewhat, since all values are escaped.
