Fitering an array

[format]

Hi Guys, I got great help here a few years ago and I wonder if I can ask another related question.

 

I am using the floowing to get the smallest quote from the array below:

 

$minSLevel = min($SLevels); // get minimum value
$minSLevel[0] = str_replace(',', '', $minSLevel[0]);

 

Array ( [0] => Array ( [0] => 35.18 [1] => Royal London ) [1] => Array ( [0] => 34.18 [1] => Zurich Life ) [2] => Array ( [0] => 32.74 [1] => Friends First ) [3] => Array ( [0] => 39.13 [1] => Aviva ) [4] => Array ( [0] => 40.59 [1] => Irish Life ) [5] => Array ( [0] => 35.26 [1] => New Ireland ) )

 

Works great.

 

Is it possible to filter the above to find value of [0] where [1] = Zurich Life

 

Many thanks for any help given.  Very much appreciated.

If want to match or more accurately compare something you can loop through an array with a foreach or for loop using a comparison operator , can also use some regex with preg_match or preg_match_all for multiples

Check if a specific value exists in the array using in_array true/false

array_search can return the key of the array

Thanks for the quick answer, a few options to read and learn.  Would you know which option above would get me going the quickest.  I had a quick look at the documentation and could see how to get the value of [0] and matching [1].  I suspect I have some reading ahead of me, just not sure which methos above I should start with.  Many thanks

I suppose that will depend the rest of your code and what doing with it.

Hmmm,all I want is to find the Zurich Life entry and its matching quote.  Thats it really.  Sorry if not using correct terms etc.

You could try something like this:

$matchingIndex = '';
foreach($yourArray as $currIndex => $subArray) {
    if($subArray[1] == 'Zurich Life') {
        $matchingIndex = $currIndex;
        break;  //break out of the loop, since you found Zurich Life
    }
}

Reconfgure your array so it is more useful, like

Array
(
    [Royal London] => 35.18
    [Zurich Life] => 34.18
    [Friends First] => 32.74
    [Aviva] => 39.13
    [Irish Life] => 40.59
    [New Ireland] => 35.26
)

This will do it

$data = array ( 
    array ( 35.18 , 'Royal London' ) ,
    array ( 34.18 , 'Zurich Life' ) ,
    array ( 32.74 , 'Friends First' ) ,
    array ( 39.13 , 'Aviva' ) ,
    array ( 40.59 , 'Irish Life' ) ,
    array ( 35.26 , 'New Ireland' ) 
    );
// reconfigure
$companies = array_column($data,1);
$prices = array_column($data,0);
$newdata = array_combine($companies, $prices);

echo $newdata['Zurich Life'];    //--> 34.18

Many thanks to you all for your replies.  Lots to take in.  cyberRobot, I tried your suggestion and it worked a charm.  Barrand, your suggetion also make sperfect sence.  Thank you for this.  Good help like this is worth its weight in gold, especialy when on the back foot with time.

 

Thanks again.
