How can PHP beginners improve their understanding of basic programming concepts to avoid errors like mixing object and array syntax?

When mixing object and array syntax in PHP, beginners can improve their understanding by practicing with simple examples and focusing on the differences between objects and arrays. One way to avoid this error is to consistently use the arrow (->) notation for objects and square brackets ([]) for arrays.

// Correct usage of object and array syntax
$object = new stdClass();
$object->property = 'value';

$array = [];
$array['key'] = 'value';
