SQLite3Stmt::bindValue
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
SQLite3Stmt::bindValue — Binds the value of a parameter to a statement variable
Beschreibung
Binds the value of a parameter to a statement variable.
Before PHP 7.2.14 and 7.3.0, respectively, once the statement has been executed, SQLite3Stmt::reset() needs to be called to be able to change the value of bound parameters.
Parameter-Liste
-
param -
Either a string (for named parameters) or an int (for positional parameters) identifying the statement variable to which the value should be bound. If a named parameter does not start with a colon (
:) or an at sign (@), a colon (:) is automatically preprended. Positional parameters start with1. -
value -
The value to bind to a statement variable.
-
type -
The data type of the value to bind.
-
SQLITE3_INTEGER: The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8 bytes depending on the magnitude of the value. -
SQLITE3_FLOAT: The value is a floating point value, stored as an 8-byte IEEE floating point number. -
SQLITE3_TEXT: The value is a text string, stored using the database encoding (UTF-8, UTF-16BE or UTF-16-LE). -
SQLITE3_BLOB: The value is a blob of data, stored exactly as it was input. -
SQLITE3_NULL: The value is a NULL value.
As of PHP 7.0.7, if
typeis omitted, it is automatically detected from the type of thevalue: bool and int are treated asSQLITE3_INTEGER, float asSQLITE3_FLOAT, null asSQLITE3_NULLand all others asSQLITE3_TEXT. Formerly, iftypehas been omitted, it has defaulted toSQLITE3_TEXT.Hinweis:
If
valueisnull, it is always treated asSQLITE3_NULL, regardless of the giventype. -
Rückgabewerte
Returns true if the value is bound to the statement variable, Bei einem Fehler wird false zurückgegeben..

Beispiele
Beispiel #1 SQLite3Stmt::bindValue() example
<?php
$db = new SQLite3(':memory:');
$db->exec('CREATE TABLE foo (id INTEGER, bar STRING)');
$db->exec("INSERT INTO foo (id, bar) VALUES (1, 'This is a test')");
$stmt = $db->prepare('SELECT bar FROM foo WHERE id=:id');
$stmt->bindValue(':id', 1, SQLITE3_INTEGER);
$result = $stmt->execute();
var_dump($result->fetchArray(SQLITE3_ASSOC));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
array(1) {
["bar"]=>
string(14) "This is a test"
}
