$iph_correction_values[4] = $ic_din_exists_01;

$iph_correction_values[7] = $ic_din_exists_02;

 

$iph_correction_cnames = implode($iph_correction_cnames ,",");

        $iph_correction_values = implode($iph_correction_values,"','");

"isset — Determine whether a variable is set"

 

http://php.net/isset

 

 

Example:

 

 

<?php
$var = "blah";
if(isset($var)) {
    echo 'var is set';
}

if(isset($othervar)) {
    echo 'othervar is set';
}

 

would ouput var is set.
