如何计算while循环后的数组中的字符

Question

请问你有什么想法如何计算while循环后字符串$chars中的所有字符？

$x = 0; 
$b = 0; 

while ($x++ < 10) { 
    echo $chars = $item->zodziai[$b++]; 
    echo ' '; 
} 

echo strlen($chars);

串连人物再算上他们

<?php 
$x = 0; $b = 0; 
$char = ''; //define a variable to collect all the chars 
while ($x++ < 10) { 
    $char .= $item->zodziai[$b++]; //add to the char 
    echo $chars = $item->zodziai[$b++]; echo ' '; 
} 
echo strlen($char); //then count all the array combined 
?>
