PHP Arrays : How to Find the Lowest/Highest Value

Question

I have two array like this :

$array1 = array(1,1,2,3,3,4,5); //remember that i have two '1' value in this array
$array2 = array($url1, $url2, $url3, $url4, $url5, $url6);

I wish to find the lowest/highest value in $array1 then link to $url1/$url5 like this :

<a href="$url1">1</a> or <a href="$url6">5</a>

How I can make this happen using PHP? Any help would be greatly appreciated Thanks

Answer 1

Use the max() & min() function

max — Find highest value
min — Find lowest value

Example code:

$max = max($array);
$min = min($array);

Answer 2

If the array is already sorted, use $array2[0] and $array2[count($array2)-1] .

If it's not already sorted, you can use this to sort the arrays.

array_multisort($array1, SORT_NUMERIC, $array2);
$lowest = $array2[0];
$highest = $array2[count($array2)-1];

Answer 3

据我了解，您需要这两个功能： max ， min

Answer 4

try this

$maxValueKeys = array_keys($array1, max($array1)); // Your min value indexes
$minValueKeys = array_keys($array1, min($array1)); // Your max value indexes

But it isn't an associative array
