Php在数组中添加重复值

I have an array which contain multiple values inside it, all i want is to find duplicate items and add the number of times they are inside an array. Here goes an example

$someVar = array('John','Nina','Andy','John','Aaron','John','Zack','Kate','Nina');

I want my final result to look like

John = 3;
Nina = 2;

and so on.

EDIT | These values are dynamic i have no idea what these names going to be.

Thanks

Use array_count_values() and array_filter() to achieve this.

$result = array_filter( array_count_values( $someVar), function( $el) {
    return $el > 1; 
});

$result will be an associative array containing the names as keys and the number of times they occur as values, but only if they were duplicated in the $someVar array.

Here is a demo showing the correct output.
