SQLite3Stmt::bindParam
Binds a parameter to a statement variable
&reftitle.description;
public boolSQLite3Stmt::bindParam
mixedsql_param
mixedparam
inttype
Binds a parameter to a statement variable.
Before PHP 7.2.14 and 7.3.0, respectively,
SQLite3Stmt::reset must be called after the first call to
SQLite3Stmt::execute if the bound value should be properly
updated on following calls to SQLite3Stmt::execute.
If SQLite3Stmt::reset is not called, the bound value will
not change, even if the value assigned to the variable passed to
SQLite3Stmt::bindParam has changed, or
SQLite3Stmt::bindParam has been called again.
&reftitle.parameters;
sql_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.
param
The parameter to bind to a statement variable.
type
The data type of the parameter 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 param: boolean
and integer 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.
If param is &null;, it is always treated as
SQLITE3_NULL, regardless of the given
type.
&reftitle.returnvalues;
Returns &true; if the parameter is bound to the statement variable, &false;
on failure.

notation.

<function>SQLite3Stmt::bindParam</function> Usage
This example shows how a single prepared statement with a single parameter
binding can be used to insert multiple rows with different values.
exec("CREATE TABLE foo (bar TEXT)");
$stmt = $db->prepare("INSERT INTO foo VALUES (:bar)");
$stmt->bindParam(':bar', $bar, SQLITE3_TEXT);
$bar = 'baz';
$stmt->execute();
$bar = 42;
$stmt->execute();
$res = $db->query("SELECT * FROM foo");
while (($row = $res->fetchArray(SQLITE3_ASSOC))) {
var_dump($row);
}
?>
]]>
&example.outputs;
string(3) "baz"
}
array(1) {
["bar"]=>
string(2) "42"
}
