Find last of match string automatically
<p>I want to make id for entries as long as 7 digits.. 
while first entry is created, it will get id is 0000001
And my problem is i want to get id and add to 1 every time new entry is created..</p>

<p>I have a bunch of code and still confuse to implement it.</p>

<pre><code>$str_rep = "0000123";
$str_rep2 = "0005123"; // My character string can be like this
$str_rep3 = "0009123"; // My character string can be like this

$match_number= array(1,2,3,4,5,6,7,8,9); // I create array to do it automatically but it was not work.

// I do it manually
$get_str = strstr($str_rep, "1");
$get_str = strstr($str_rep2, "5");
$get_str = strstr($str_rep3, "9");

// Result
echo $get_str . "&lt;br&gt;";
echo $get_str2 . "&lt;br&gt;";
echo $get_str3 . "&lt;br&gt;";
</code></pre>

<p>Thanks in advance</p>
