failure with find() function using PHP with Silex - php

Question

Here is the failure message I get in Terminal running 'phpunit tests':
1) StylistTest::test_find
null does not match expected type "object".
/Users/evanbutler/Desktop/hairSalonApp/tests/StylistTest.php:163
Here's my test method:
function test_find()
{
//Arrange
$name = "Stylist Jane";
$id = 1;
$name2 = "Stylist Bob";
$id2 = 2;
$test_stylist = new Stylist($name, $id);
$test_stylist->save();
$test_stylist2 = new Stylist($name2, $id2);
$test_stylist2->save();
//Act
$result = Stylist::find($test_stylist->getId());
//Assert
$this->assertEquals($test_stylist, $result);
}
And here's my method:
static function find($search_id)
{
$found_stylist = null;
$stylists = Stylist::getAll();
foreach($stylists as $stylist) {
$stylist_id = $stylist->getId();
if ($stylist_id == $search_id) {
$found_styist = $stylist;
}
}
return $found_stylist;
}
Here's my getAll method:
static function getAll()
{
$returned_stylists = $GLOBALS['DB']->query("SELECT * FROM stylists;");
$stylists = array();
foreach($returned_stylists as $stylist) {
$name = $stylist['name'];
$id = $stylist['id'];
$new_stylist = new Stylist($name, $id);
array_push($stylists, $new_stylist);
}
return $stylists;
}

I've been staring at this for way too long and I'm totally stumped.

Change
$found_styist = $stylist;
to
$found_stylist = $stylist;
You need a better IDE man. Simple static analysis could tell you about the unused variable.
