array_intersect and match multiple values same time

Question

In this script, you can see i try validate if 2 values - Jhon 34 -there are in the string called $values the same time, when i send the search i use 2 o 3 words and the idea it´s verification if find exactly this 3 or 2 words, etc, inside array

<?php  
$values="Jhon,Smith,252546,34,house,car,phone";
$post="Jhon 34";

$exp_values=explode(",",$values); 
$exp_post=explode(" ",$post);

$result=array_intersect($exp_post,$exp_values);

foreach ($result as $results) {    
    if(count($result)==count($exp_post)) { 
        echo $results; 
        print "<br>"; 
    }
} 
?>

I use count for show result only if the intersect elements it´s the same number as in the $post, because $post show values i want search inside $values, the result it´s ok if the same words find inside $values

The results it´s wrong because detect one word but i need detect all words i send, if array have all these words result must be ok, if haven´t this result it´s bad

Answer 1

You have the if and foreach backwards. First check if the count is the same to know that the post is valid, then show the results.

And instead of a loop, you can simply implode() $result:

if (count($result) == count($exp_post)) {
    echo implode('<br>', $result);
} else {
    echo "Invalid input";
}
