Php function missing one record - php

Question

I have a php function
function getMembersByFamilyNumber($familyNumber){
$html = "";
$query = db_execute("SELECT * FROM `family_members` WHERE `family_number` = '".$familyNumber."' and `isActive`= '1' and `isDelete`= '0' ORDER BY id DESC");
$check = mysql_fetch_assoc($query);
if ($check) {
while($result = mysql_fetch_assoc($query)){
extract($result);
$html.='
<li>
<time class="cbp_tmtime" datetime="2013-04-10 18:30"><span>'.$familyNumber.'</span> <span>'.$relation_head.'</span></time>
<div class="cbp_tmicon cbp_tmicon-phone"></div>
<div class="cbp_tmlabel">
<h2>'.$name.'</h2>
<button type="button" class="btn btn-success pull-right" onclick="editPageContent(\'editpagecontent\',\'editMember\',\''.$id.'\');">Edit</button>
<button type="button" class="btn btn-danger pull-right" onclick="deletePageContent(\'deletepagecontent\',\'deleteHead\',\''.$id.'\');">Delete</button>
<ul>
<li>Age: '.$age.' years old</li>
<li>Education: '.$education.'</li>
<li>Occupation: '.$occupation.'</li>
<li>Alive: '.$alive.'</li>
<li>Phone: '.$phone.'</li>
<li>CNIC: '.$cnic.'</li>
</ul>
</div>
</li>
';
}
return $html;
exit;
}else{
return "<li><h2>No members found.</h2></li>";
}
}
Is is returning only one record, but in database there is two records against this query, whenever i i execute this query in MySQL it returning two rows, but whenever i run this code it return only second record, missing first record, every time it missing first record. means if my table have 5 records this function returns 4 records and miss 1st record. Why this happens? help me.

Answer 1

Use mysql_num_rows($query) not use
$check = mysql_fetch_assoc($query);
if ($check) {
This is correct solution:
if (mysql_num_rows($query) > 0) {
while($result = mysql_fetch_assoc($query)){
