SQLite3Stmt::bindValue
Binds the value of a parameter to a statement variable
Description
public bool SQLite3Stmt::bindValue(stringint $param, mixed $value, int $type = SQLITE3_TEXT)
Caution
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.
Parameters
-
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 with 1.
-
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 type is omitted, it is automatically
detected from the type of the value: bool
and int are treated as SQLITE3_INTEGER,
float as SQLITE3_FLOAT, null
as SQLITE3_NULL and all others as SQLITE3_TEXT.
Formerly, if type has been omitted, it has defaulted
to SQLITE3_TEXT.
Note:
If value is null, it is always treated as
SQLITE3_NULL, regardless of the given
type.
Return Values
Returns true if the value is bound to the statement variable, or false on failure.
Examples
Example #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));
?>
The above example will output:
array(1) {
["bar"]=>
string(14) "This is a test"
}
