Laravel 5 Collections: Filtering Collection Elements Using Strict Comparison Operators With whereStrict

Laravel 5

April 22, 2018 ·1 min read · John Koster

The whereStrict method is similar to the where method, but it will always use strict comparisons when determining the results to return.

#Signature

1public function whereStrict(
2    $key,
3    $value
4);

#Example Use

The $sampleCollection collection instance will be used in the following examples:

 1$sampleCollection = collect([
 2    [
 3        'name'  => 'Desk',
 4        'price' => 499.99
 5    ],
 6    [
 7        'name'  => 'Office Chair',
 8        'price' => '499.99'
 9    ]
10]);

If you noticed, the first product (Desk) has its price specified as a float value, and the second product (Office Chair) has its specified as a string.

The following example are behaviorally equivalent:

1$products = $sampleCollection
2                ->where('price', '===', 499.99, true);
3 
4$products = $sampleCollection
5                ->whereStrict('price', 499.99);

In both bases in the previous example, the $products collection would only contain the product Desk; this is because the whereStrict method (as well as the where method when the $operator is set to ===) will compare the types on both sides of the comparison operator.
