[SOLVED] Why doesnt this work?

[therealwesfoster]

I have a code that gets the longest (strlen) index from an array, and saves in to a variable:

I get no errors, but the $length var stays at 0.. what am i missing lol?

 

<?php
// Get longest index
$ckline = explode("; ",$ck);
$length = 0;

for ($i=0; $i<=count($ckline); $i++)
{
if ( $length < strlen($ckline[$i]) )
{
	$length = $ckline[$i];
}
else
{
	$length = $length;
}
}

echo $length;
?>

Shouldn't you be setting length to strlen($ckline[$i]);

 

<?php
          
// Get longest index
$ckline = explode("; ",$ck);
$length = 0;

foreach ($ckline as $ck)
{
$length = max($length, strlen($ck));
}

echo $length;
?>

Your comparison is wrong.

 

Try this:

<?php
$ckline = explode("; ",$ck);
$length = 0;

foreach ($ckline as $line)
      $length = (strlen($line) > $length)?strlen($line):$length;

echo $length . '<br>';
?>
