I have this array:
$myArray = array("0x40x40" => 64, "0x50x40" => 65, "0x60x40" => 66);
Now I want to find the smalles value, in this case its 64 (the first key/value pair). Is there a way other than looping through the array and to compare the values? The smallest value is not always the first and the values are not sorted by the way.
Thanks!
You can use the min() function to get your answer nicely.
echo min(2, 3, 1, 6, 7); // 1
or
$myArray=array(2, 3, 1, 6, 7);
echo min($myArray); // 1
min() loops through the array. Algorithmically, there's nothing better one can do unless the array has a known structure (sorted ascending/descending, or descending in first part, ascending in second, ...).Using min:
$myArray = array(
"0x40x40" => 64, "0x50x40" => 65, "0x60x40" => 66, "0x70x40" => 67, "0x80x40" => 68, "0x90x40" => 70, "0x100x40" => 71, "0x110x40" => 74, "0x120x40" => 76);
echo min($myArray);
Use below statement in your code and you are done.
min($myArray);
will return # array('0x40x40')
$myArray = array(
"0x40x40" => 64,
"0x50x40" => 65,
"0x60x40" => 66,
);
array_keys($myArray, min($myArray));
If you only needs the lowest or highest value
$myArray = array( "0x40x40" => 64, "0x50x40" => 65, "0x60x40" => 66 );
asort ( $myArray );
$item = current( $myArray );
This is for lowest to highest, in reverse U would need the arsort() function
