pg_insert Überträgt Werte aus einem Array in eine Tabelle


mixed pg_insert ( resource $connection , string $table_name , array $assoc_array [, int $options = PGSQL_DML_EXEC ] )

pg_insert() fügt die Werte des assoc_array in die Tabelle table_name ein. Falls options angegeben wurde, wird pg_insert() auf assoc_array mit den angegebenen Optionnen angewendet.


Diese Funktion ist EXPERIMENTELL. Das Verhalten, der Funktionsname und alles Andere, was hier dokumentiert ist, kann sich in zukünftigen PHP-Versionen ohne Ankündigung ändern. Seien Sie gewarnt und verwenden Sie diese Funktion auf eigenes Risiko.



PostgreSQL Verbindungskennung.


Name der Tabelle, in die die Zeilen eingefügt werden sollen. table_name muss mindestens soviele Spalten haben, wie das assoc_array Elemente.


Ein array dessen Indizes Feldnamen von table_name sind und dessen Werte in die entprechenden Spalten eingefügt werden.


Jede Kombination aus PGSQL_CONV_OPTS, PGSQL_DML_NO_CONV, PGSQL_DML_EXEC, PGSQL_DML_ASYNC oder PGSQL_DML_STRING. Falls PGSQL_DML_STRING bei den options angegeben wurde, wird der Abfrage-String zurückgegeben.


Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben. Falls die Konstante PGSQL_DML_STRING in den options übergeben wurde, wird ein string zurückgegeben.


Beispiel #1 pg_insert() Beispiel

// Das ist sicher, da $_POST automatisch konvertiert wird
$res pg_insert($dbconn'post_log'$_POST);
  if (
$res) {
"Der Inhalt von $_POST wurde protokolliert\n";
  } else {
"Vermutlich wurden falsche Eingabedaten gesendet\n";

it seems to fail silently if you try to insert somehting with a mis-named column

If you need schema support, this function will do something similar to pg_insert:

function pg_insert_with_schema($connection, $table, $updates)
 $schema = 'public';
 if (strpos($table, '.') !== false)
    list($schema, $table) = explode('.', $table);

    if (count($updates) == 0) {
        $sql = "INSERT INTO $schema.\"$table\" DEFAULT VALUES";
            return pg_query($sql);
        } else {
 $sql = "INSERT INTO $schema.\"$table\" ";
 $sql .= '("';
 $sql .= join('", "', array_keys($updates));
 $sql .= '")';

 $sql .= ' values (';
 for($i = 0; $i < count($updates); $i++)
   $sql .= ($i != 0? ', ':'').'$'.($i+1);
 $sql .= ')';
 return pg_query_params($connection, $sql, array_values($updates));

Today at work I isolated a problem I was having with this function to how I was formatting the date.  I was assigning the date in my code as follows:

$today = date( "Ymd" ); // ISO 8601

This format is acceptable to PostgreSQL, as verified by their documentation and buy tests using psql.  However, to make it work in my code, I had to make the following change:

$today = date( "Y-m-d" ); // also ISO 8601 format

Had a few issues while trying to run this in PHP 4.4.0:

- I could not get it to work with column names that are SQL reserved words (example: desc, order). I was forced to change the column names in order to use the function. I could not put the column names in quotes, because that caused pg_convert() to fail.

- Function was returning false until I passed the PGSQL_DML_EXEC option.

Beware of the following: pg_insert() and pg_update() are adding slashes to all character-like fields they work with. This makes them SQL injection super-safe, but there are unwanted consequences, as follows:

If you have a regular setup with magic_quotes_gcp=On, and you use pg_insert() or pg_update(), you will end up with fields that look as if you used addslashes() twice. To solve this, you can use stripslashes() on the data just before using it with pg_insert() or pg_update().

There's another alternative, which seems better to me. Why make yourself crazy all over the code, adding slashes, stripping slashes, worrying whether magic_quotes_gpc is on or off and so on and so forth? Why do this, when the only place you actually need those slashes is right when you push the data into the database?

So why not get rid of your addslashes() and stripslashes() from all over your code, and turn magic_quotes_gcp off. As long as you always use pg_insert() and pg_update() to do your DB work, you're SQL-injection safe AND slash-headache free.

Next version :) My version checks whether value is bool, null, string or numeric and if one of the values is not function returns false if not. null values are inserted as NULL, bool as true or false and strings are add-shlashed before adding to query string. Note, that this function is not safe. SQL injection is possible with column names if you use $_POST or something similar as a $array.

function db_build_insert($table, $array) {
  if (
count($array)===0) return false;
$columns = array_keys($array);
$values = array_values($array);

  for (
$i = 0, $c = count($values); $i$c; ++$i) {
    if (
is_bool($values[$i])) {
$values[$i] = $values[$i]?'true':'false';
    } elseif (
is_null($values[$i])) {
$values[$i] = 'NULL';
    } elseif (
is_string($values[$i])) {
$values[$i] = "'" . addslashes($values[$i]) . "'";
    } elseif (!
is_numeric($values[$i])) {

"INSERT INTO $table ($column_quote" . implode(', ', $columns) .
") VALUES (" . implode(', ', $values) . ")";

Returns SQL statement, slight improvement on the code from 'rorezende at hotmail dot com'.  This version adds bool values correctly.It also checks to make sure there is actually a value in the array before including it in the sql statement. (ie: null values or empty strings won't be added to the sql statement)

function db_build_insert($table,$array)

$str = "insert into $table ";
$strn = "(";
$strv = " VALUES (";
$name,$value) = each($array)) {

is_bool($value)) {
$strn .= "$name,";
$strv .= ($value ? "true":"false") . ",";

is_string($value)) {
$strn .= "$name,";
$strv .= "'$value',";
       if (!
is_null($value) and ($value != "")) {
$strn .= "$name,";
$strv .= "$value,";
$strn[strlen($strn)-1] = ')';
$strv[strlen($strv)-1] = ')';
$str .= $strn . $strv;

Time is money, then I write a function similar to pg_insert in PHP (only output sql statement) :

   function db_mount_insert($table,$array) {

    $str = "insert into $table (";
    while(list($name,$value) = each($array)) {       
        $str .= "$name,";       
    $str[strlen($str)-1] = ')';
    $str .= " values (";
    while(list($name,$value) = each($array)) {       
            $str .= "'$value',";
            $str .= "$value,";
    $str[strlen($str)-1] = ')';
    $str .= ";"    ;
    return $str;
