Question

I have an array about 1000 values, I’ve just shuffled them using shuffle(). Now I want to echo the shuffled results. But here’s the catch, can it be done without looping through the array or displaying array ‘syntax’?

ie:

<?php
    $myarray = array('a','b','c','d');
    shuffle($myarray);
    echo array_echo_vals_only($myarray);
    /*
    should echo: dbca
    */
?>

Answer 1

Simply Use Implode

echo implode($myarray);

Or Just reduce the array with array_reduce

echo array_reduce($myarray, function($a,$b){$a .= $b; return $a;});

Play around with vsprintf

echo vsprintf(str_repeat("%s", count($myarray)), $myarray);

We also have some crazy ways ..

echo preg_replace("/\W/", "", json_encode($myarray));

Or

echo str_replace(array("]","[","\"",","), "", json_encode($array));

What i think ….

Assign entire array values to string without looping in PHP

Loop is not a bad solution .. you may as well give it a try … Example :

$l = "";
$c = count($array);
for($i = 0; $i < $c; ++ $i) {
    $l .= $array[$i];
}
echo $l;
