PDOStatement::setFetchMode()
reset default fetch() mode for a statement to PDO_FETCH_BOTH
PDOStatement::setFetchMode(PDO_FETCH_NUM)
PDOStatement::setFetchMode(PDO_FETCH_ASSOC)
PDOStatement::setFetchMode(PDO_FETCH_BOTH)
PDOStatement::setFetchMode(PDO_FETCH_OBJ)
set default fetch() mode for a statement.
PDOStatement::setFetchMode(PDO_FETCH_COLUMN, int colno)
set default fetch() mode to retrieve colno-th column on each fetch() call.
PDOStatement::setFetchMode(PDO_FETCH_CLASS, string classname [, array ctor args])
set default fetch() mode to create an instance of classname,
calling it's ctor, passing the optional ctor args.
The names of the columns in the result set will be used as property names on
the object instance. PPP rules apply.
[NOTE: calling ctor is not yet implemented]
[TODO: this might crash PHP for persistent PDO handles]
PDOStatement::setFetchMode(PDO_FETCH_INTO, object obj)
Similar to PDO_FETCH_CLASS, except that each iteration will update the
supplied object properties.
[TODO: this might crash PHP for persistent PDO handles]
The default fetch() mode is used when no parameters are passed to
PDOStatement::fetch(). When using a statement in an iterator context,
PDOStatement::fetch() is called implicitly on each iteration.
object PDO::queryAndIterate(string sql, <PDOStatement::setFetchMode args>)
This is semantically equivalent to:
$stmt = $pdo->prepare($sql);
$stmt->execute();
$stmt->setFetchMode($args);
return $stmt;
Example/Intended usage:
/* fetch an array with numeric and string keys */
foreach ($pdo->queryAndIterate("select NAME, VALUE from test") as $row) {
debug_zval_dump($row);
}
/* fetch the value of column 1 into $row on each iteration */
foreach ($pdo->queryAndIterate("select NAME, VALUE from test",
PDO_FETCH_COLUMN, 1) as $row) {
debug_zval_dump($row); // string(3) "foo"
}
/* create a new instance of class Foo on each iteration */
foreach ($pdo->queryAndIterate("select NAME, VALUE from test",
PDO_FETCH_CLASS, 'Foo') as $row) {
debug_zval_dump($row);
/*
Object(Foo)#4 (2) refcount(2){
["NAME"]=>
string(12) "foo220051429" refcount(2)
["VALUE"]=>
string(12) "bar789825748" refcount(2)
}
*/
}

add DOMText isElementContentWhitespace (spec name change)
- old props/method kept for BC.
- spec names changed when Level 3 went from Draft to Recommendation
nuke some unused code
- Extensions which delete global variables need to use new special function
- delete_global_variable() (I'm about to rename it) to remove them.
- Will post to internals@ or via commit messages if there's anything else.
