How will i separated by comma the result of array_diff i tried this code but it gave me Warning: explode() expects parameter 2 to be string, array give Warning: Invalid argument supplied for foreach()
<?php
$row['IMEI_MX'] = '123,222,333';
$row2["IMEI_MX"] = '123,222';
$imei = $row["IMEI_MX"];
$imeiserial = explode(',', $imei);
$imeitransfer = $row2["IMEI_MX"];
$imeitransferserial = explode(',', $imeitransfer);
$a1 = $imeiserial;
$a2 = $imeitransferserial;
$result = array_diff($a1,$a2);
$separate = implode(' ', $result);
foreach($separate as $is){
echo $is;
}
I think you just want to show the values of first string which are not in second string .
Tried this one
<?php
$row['IMEI_MX'] = '123,222,333,444';
$row2["IMEI_MX"] = '123,222';
$imei = $row["IMEI_MX"];
$imeiserial = explode(',', $imei);
$imeitransfer = $row2["IMEI_MX"];
$imeitransferserial = explode(',', $imeitransfer);
$a1 = $imeiserial;
$a2 = $imeitransferserial;
$result = array_diff($a1,$a2);
$sting = implode(',',$result);
echo $sting;
?>
It will result as
333,444
