I am not exploding $one and using our own code with minor changes. I am only changing condition and echoing only selected instead of selected="selected"
<body>
<select name="city[]" size=5 multiple="multiple">
<option value="pune"<?php if (substr_count($one, 'pune') > 0 )
{
echo
'selected';
} ?>>pune</option>
<option value="mumbai"<?php if (substr_count($one, 'mumbai') > 0) { echo
'selected'; } ?>>mumbai</option>
<option value="nasik"<?php if (substr_count($one, 'nasik') > 0) { echo
'selected' ;} ?>>nasik</option>
<option value="surat"<?php if (substr_count($one, 'surat') > 0) { echo
