php如果许多条件中的一个是真的或者全部都是假的

Question

<?php
$input = '5' ;
$id = array(1,2,3,4,5,6,7);

How to match if $input is in $id ? How to do something if it is false (No match), like if $input='10' echo No match?

Answer 1

To check if value is contained in array, you can use native PHP function in_array()

if(in_array($input, $id)){
    echo 'Match';
}else{
    echo 'No match';
}
