Code after a return statement in a PHP function
(3 answers)
Closed 6 months ago.
please check my code. i have some program to return the third largest word in a given array.
if in the third largest word has a same letters long, so retrun the last one.
for example ['world', 'hello', 'before', 'all', 'dr'] the output should be 'hello'.
my program is working fine, however when I want to echo the $result, the code doesn't execute.
here is my code:
<?php
$array = ['world', 'hello', 'before', 'all', 'dr'];
$array2 = [];
foreach ($array as $value) {
$array2[$value] = strlen($value);
}
asort($array2);
$slice = array_slice($array2, -3);
$array3 = [];
foreach ($slice as $key => $value) {
$array3[] = $key;
}
$result = "THIS RESULT SHOULD BE RE ASSIGNED, BUT WHY !!!!!";
for ($i = count($array3) - 1; $i >= 0; $i--) {
if ($i == 0) {
$result = $array3[$i];
return $result;
}
if (strlen($array3[$i]) == strlen($array3[$i - 1])) {
$result = $array3[$i];
return $result;
}
}
echo "THIS LINE IS NOT WORKING";
echo $result;

Answer 1

You have to use break instead of return.
<?php
$array = ['world', 'hello', 'before', 'all', 'dr'];
$array2 = [];
foreach ($array as $value) {
$array2[$value] = strlen($value);
}
asort($array2);
$slice = array_slice($array2, -3);
$array3 = [];
foreach ($slice as $key => $value) {
$array3[] = $key;
}
$result = "";
for ($i = count($array3) - 1; $i >= 0; $i--) {
if ($i == 0) {
$result = $array3[$i];
break;
}
if (strlen($array3[$i]) == strlen($array3[$i - 1])) {
$result = $array3[$i];
break;
}
}
echo $result;

Answer 2

Simply remove the return statements in the loop. instead of return, perhaps use break.

Answer 3

You can try this way as well.
<?php
/**
* Read more about here
* https://www.php.net/manual/en/function.usort.php
*/
function sort_by_length($a,$b){
return strlen($b)-strlen($a);
}
$array =['world', 'hello', 'before', 'all', 'dr'];
usort($array,'sort_by_length'); // sorting array with a custom function.
if(count($array) >= 2) {
$sliced = array_slice($array, 2);
$result = $sliced[0];
/**
* Read more at
* 1. https://www.php.net/manual/en/function.next.php
* 2. https://www.php.net/manual/en/function.current.php
*/
while(strlen(current($sliced)) == strlen(next($sliced))){
$result = current($sliced);
}
echo $result;
} else {
echo "Not enough items in array.";
}
This will output
hello

Answer 4

Remove the return .It return the value so any code after it will not be executed.
