mysql_fetch_row returns value above zero despite actually being zero
I'm running the following query but $new
returns 0
:
$count = mysql_query("SELECT COUNT(*) FROM flagged WHERE status=0") or die(mysql_error());
$new = mysql_fetch_row($count);
if ($new != 0) {
echo "<script language=\"javascript\">$.titleAlert(\"New Logs - ($new[0])\");</script>";
}
Problem is the if-condition keeps getting met when it shouldn't when $new != 0
I even tried:
if ($n开发者_高级运维ew > 0) {
//update title about new logs
}
Either way, the title is still updated and I'm not sure why.
New Logs - (0)
just do
var_dump($new);
and you'll see why your if
doesn't work
Not sure what you mean. $new
should be an array not a scalar value per the PHP documentation.
mysql_fetch_row documentation
this code
$new = mysql_fetch_row($count);
makes $new becomes an array
try to compare it like this:
if ($new[0] != 0)
or even better, so You would be 100% sure it's what You need.
if (count($new) == 1 && intval($new[0]) != 0)
mysql_fetch_row
should return an array or FALSE
.
Maybe adjust your conditional to:
if ( !$new ) {
// some code here
}
