What does => in php mean?

=> in php is generally used as a connector between array keys and elements. Simply put, the => symbol is used to separate keys and values. The left side represents the key and the right side represents the value.

For example: 

$arr = array(
'a'=>'123',
'b'=>'456'
);
foreach($arr as $key=>$val){
//$key是数组键名
//$val是数组键名对应的值
}
