In PHP how can I quickly tell if all values in array are identical?

The Arrays. equals() method checks the equality of the two arrays in terms of size, data, and order of elements. This method will accept the two arrays which need to be compared, and it returns the boolean result true if both the arrays are equal and false if the arrays are not equal.
Using Arrays. equals(array1, array2) methods − This method iterates over each value of an array and compare using equals method. Using Arrays. deepEquals(array1, array2) methods − This method iterates over each value of an array and deep compare using any overridden equals method.
Javascript Useful Snippets — allEqual() In order to check whether every value of your records/array is equal to each other or not, you can use this function. allEqual() function returns true if the all records of a collection are equal and false otherwise.
You can use the test:
count(array_unique($arr)) == 1;
Alternatively you can use the test:
$arr === array_fill(0,count($arr),$arr[0]);
$results = array_unique($myArray);
if(count($results) == 1){
// $myArray is all duplicates
}
