Searching against an array?

[gurpalrattu]

I'm working on an assignment for my PHP class and I'm stuck.

 

Basically what I'm trying to do is take the input from an html form and check that it matches against a key or a value in an associative array I created in a separate php file. I'm printing each pair like "key => value", and if either the key or value matches then that line will be bolded.

 

I'm using the array_key_exists and in_array functions to match against the array, but whats happening is if it finds that the input matches then every line becomes bolded. How do I make it so that one one selected line will be bolded and the rest will print out normally?

 

I can post the text from my file if needed, but I'd rather do it this way as I don't want to just be told what to write, I wanna learn this.

 

Edit: I'm also using the foreach function in conjunction with the other two functions, so I understand why they're all printing out bolded, I just would like to know what how use to just print one line

pseudocode

get input
for each array element
   if matches input
        print bold
   else
        print plain
   end if
end for

Okay, so I figured out how to check a string against an array and I can get the result that I want, but if I put in more than one string then it stops working.

 

 

this is the function I'm using:

 

function tester($comp,$search)
{
    ksort($comp);

    foreach ($comp as $key => $value){
        if ($search == $key || $search == $value){
                print "<strong>"."*=*=*$key ==> $value"."</strong>"."<br />";
        }
        
        else {
            print "$key ==> $value <br />";
        }
        }
        }

 

As you can see I am passing in the array($comp) and the search values($search), if there is only one search term then this works, but if I put in more than one then it doesn't work. I tried to use the explode function, but that doesn't seem to work and now I'm stuck and I'm not sure what to do.

$comp = array(

            'aaa' => 'bbb',

            'ccc' => 'ddd',

            'eee' => 'fff',

            'bbb' => 'ggg',

            'hhh' => 'kkk',

            'mmm' => 'nnn',

            'ppp' => 'qqq',

            'rrr' => 'sss',

            'ttt' => 'ccc'

        );

$search = 'kkk,ccc,bbb';


tester($comp, $search);


function tester ($comp, $search)

{

    ksort($comp);

    $asrch = explode(',', $search); // convert to array

    foreach ($comp as $k=>$v) {

        if (in_array($k, $asrch) || in_array($v, $asrch)) {

            echo "<strong>$k => $v</strong><br>";

        }

        else {

            echo "$k => $v<br>";

        }

    } 


}
