add string to variables

[newphpcoder]

Hi

Good day!

I just want to know if what syntax/code should I use to put - in my data variable.

for example I have this data.

$lot_number_indi_scan = 'LO130315002LO130318001';

I want to create a new variable and the output has added - between the lot_number_indi_scan like this:

$newlot = 'LO130315002-LO130318001';


I want to happen is first I will check the length of $lot_number_indi_scan if length is greater than 10 every lot_number_indi_scan has -
like this:
$newlot = 'LO130315002-LO130318001';


Any help is highly appreciated.

Thank you so much.

This could help you http://php.net/manual/en/function.substr.php

$lot_number_scan = "LO130315002LO130318001,LO130315003"
$lot_number_indi_scan = explode(',', $lot_number_scan);

$count_lot_str = strlen($lot_number_indi_scan);

if($count_lot_str > 11)
{
$lot_number_indi_scan = substr($lot_number_indi_scan, 0, 11) . "-" . substr($lot_number_indi_scan, 11); ;
}
else
{
$lot_number_indi_scan = $lot_number_indi_scan;
}

but instead the length is 11 it becomes 5 i don't know why.

Thank you so much.

explode() turns $lot_number_indi_scan into an Array, so your strlen() of $lot_number_indi_scan is on the "Array" object (hence 5; A-r-r-a-y).

What you need to do is loop over the $lot_number_indi_scan like such:

    $lot_number_scan = "LO130315002LO130318001,LO130315003";
    $lot_number_indi_scan = explode(',', $lot_number_scan);
    
    //$count_lot_str = strlen($lot_number_indi_scan);
    
    foreach ($lot_number_indi_scan as $tmpID => $lot_number) {
        if(strlen($lot_number) > 11)
        {
            $lot_number = substr($lot_number, 0, 11) . "-" . substr($lot_number, 11);
        }
        else
        {
            $lot_number = $lot_number; 
        }
        
        $lot_number_indi_scan[$tmpID] = $lot_number;
    }
    
    // i just put the results of the manipulation back into the original array
    echo "<pre>";
    print_r($lot_number_indi_scan);
    echo "</pre>";

    // $lot_number_indi_scan
    // Array
    // (
    //     [0] => LO130315002-LO130318001
    //     [1] => LO130315003
    // )

If the lot numbers are always in the form 1-n capital letters followed by 1-n numbers:

$str='LO130315002LO130318001';
$newStr=preg_replace('/(?<=[0-9])(?=[A-Z])/', '-', $str);
echo $newStr;"
