This article mainly introduces "php how to judge how many values of two arrays are the same". In daily operation, I believe many people have doubts about how php judges how several values of two arrays are the same. The editor consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt of "how to judge how many values of two arrays are the same". Next, please follow the editor to study!

Method: 1, use array_intersect () to compare arrays, syntax "array_intersect (array 1, array 2)", will return an intersection array; 2, use count () to get the length of the intersection array, syntax "count (array)", the length of the returned array is the number of elements with the same value.

Operating environment of this tutorial: windows7 system, PHP7.1 version, DELL G3 computer

Php's method of judging that two arrays have the same values

1. Use the array_intersect () function to compare two arrays to get the intersection elements

The array_intersect () function compares the values of two (or more) arrays and returns an intersecting array.

As you can see, the returned intersection array contains elements with the same values for all the two arrays.

You only need to calculate the length of the intersection array to know how many values are the same between the two arrays.

2. Use count () to get the length of the intersection array

The count () function can count the number of all elements in an array, or the number of attributes in an object.

$len=count ($intersect); echo the elements with the same value in the two arrays are:. $len.

At this point, the study on "how to judge how many values of two arrays are the same" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
