（初级问题）如何将Array数组转换成字符串？？

Question

我的目的是想查找这个里面是否含有00-0A-EB-02-DF-EA字符串<?$string=$arry;
$pos = strpos($string,"00-0A-EB-02-DF-EA");
if ($pos === false) 
{ 
echo "not found";
echo "<br/>";
echo $pos;
}
else
{
echo "found";
echo "<br/>";
echo $pos;
}
?>

Answer 1

<?php$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);print $comma_separated; // lastname,email,phone?>

Answer 2

$string = implode("",$arry);
