Description:
------------
Executing a prepared statement changes the type of bound parameters
to string (Tested only with pgsql driver).
This bite me when I wanted to execute an insert statement only when
the double value to be inserted actually changed, NULL being a
possible value. Unfortunatly, comparing the new value with the old
value with the !== operator didn't work, because the type-change
made the test always evaluate to TRUE.
Reproduce code:
---------------
<?php
$db = new PDO("pgsql:host=localhost dbname=test user=dummy");
$db->query("CREATE TABLE test_table ( val REAL )");
$qry = $db->prepare("INSERT INTO test_table VALUES (:val)");
$qry->bindParam(":val",$bound_val);
$bound_val = 5.2;
echo "Type before execute(): ".gettype($bound_val)."\n";
$qry->execute();
echo "Type after execute(): ".gettype($bound_val)."\n";
$db->query("DROP TABLE test");
?>
Expected result:
----------------
Type before execute(): double
Type after execute(): double
Actual result:
--------------
Type before execute(): double
Type after execute(): string
------------------------------------------------------------------------
