Bug description: $_POST variable behaves differently for form with 1 input
than multiple
Description:
------------
Under PHP 5.2.6 the $_POST variable behaves differently for html forms
with 1 input field than forms with more than one. When there is only 1
field in a form the result of $_POST['field_name'] gets returned as:
FIELD_VALUEfield_name=FIELD_VALUE
With multiple form fields the result is returned as you would expect:
FIELD_VALUE
Reproduce code:
---------------
<html>
<head>
<title>PHP 5.2.6 Form $_POST Problem</title>
</head>
<body>
<?php
if ($_POST)
{
print("Contents of \$_POST variable<br /><br />\n");
$count = count($_POST);
print("$_POST contains $count item(s).<br />\n");
foreach (array_keys($_POST) as $key)
{
$$key = $_POST[$key];
print "$key is '${$key}'<br />";
}
}
?>
<hr width="200" align="left"/>
Form with 1 input field<br /><br />
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
Field1: <input type="text" name="field1" value="value1"/><br />
<input type="submit" value="Add" />
</form>
<br />
<hr width="200" align="left"/>
Form with 2 input fields<br /><br />
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
Field2: <input type="text" name="field2" value="value2" /><br />
Field3: <input type="text" name="field3" value="value3" /><br />
<input type="submit" value="Add" />
</form>
</body>
</html>
Expected result:
----------------
... click 1st Add button ...
Contents of $_POST variable
Array contains 1 item(s).
field1 is 'value1'
... click 2nd Add button ...
Contents of $_POST variable
Array contains 2 item(s).
field2 is 'value2'
field3 is 'value3'
Actual result:
--------------
... click 1st Add button ...
Contents of $_POST variable
Array contains 1 item(s).
field1 is 'value1field1=value1'
... click 2nd Add button ...
Contents of $_POST variable
Array contains 2 item(s).
field2 is 'value2'
field3 is 'value3'
It works properly for PHP 5.2.4 on another server.
