This article mainly introduces how php determines whether the elements in the array are the same related knowledge, detailed and easy to understand, simple and fast operation, has a certain reference value, I believe everyone read this php how to determine whether the elements in the array are the same article will have some gains, let's take a look at it.

Judgment method: 1. Remove duplicate values in the array, syntax "$newArr=array_unique($arr);";2. Get the length of the array after deduplication. If the array length is 1, then the elements in the original array are the same, syntax "if(count($newArr)==1){//operation when they are the same}."

Operating environment of this tutorial: Windows 7 system, PHP7.1 version, DELL G3 computer

In php, array_unique() and count() functions can be used to determine whether all elements in an array are the same.

Realization of ideas:

Use array_unique() to remove duplicate values from an array. If two or more array values are the same, only the first value is retained and the others are removed.

Use count() to get the length of the deduplicated array

If the array length is 1, it means that there is only one element in the original array, that is, the elements in the original array are all the same.

If the array length is not 1, it means that the original array is not all the same.

Implementation method:

1. Use array_unique() to remove duplicate values from the array

2. Use count() to determine the length of the deduplicated array and determine whether the array length is 1.

Extension: Improved code, encapsulated as a functional function:
