[Resolved] Unsetting a var out of an array then using foreach

[aj3220]

Ok, what i'm trying to do here is in the code i'm telling it to take 4 fields from the db. Put them into an array. Then i tell it that if one of those vars out of the array == default.gif unset that var.. Like unset $var[2] if it is set. or if var[4] is set unset it. Then i tell it with a foreach loop to display everything in $pics that is set. Again i hope that my if statement will unset everythin in $pics that == default.gif. I get a parse error on my ifstatement and it doens't seem to work. Any suggestions?

$sql = "SELECT * FROM users WHERE user='$name'";
$result = mysql_query($sql,$con);
$row = mysql_fetch_array($result) or die(mysql_error());

    $mainpic = $row['mainpic'];

    $pic1 = $row['pic1'];
    $pic2 = $row['pic2'];
    $pic3 = $row['pic3'];
    $pic4 = $row['pic4'];

    $pics = array($pic1,$pic2,$pic3,$pic4);

         if ($pics[] == "default.gif") { unset($pics[]) } 



foreach($pics as $picname)
{
$table .= "
<td align=center><a href=http://c.com/viewimage.php?image=$picname&name=$name> <span style='text-decoration: none'><img
src=http://.com/pics/$picname height=80 width=80></a></span></td>
";
} 

The error i get with this code is
Fatal error: Cannot use [] for reading in / on line 46

 if ($pics[] == "default.gif") { unset($pics[]) } 

that is line 46
that is my problem. As if you notice i'm trying to unset the var

Which line is line 46...?

[aj3220]

if ($pics[] == "default.gif") { unset($pics[]) }

That is line 46 and where the problem lays.

What i'm trying to do is tell it that if any one of the vars in the array

ie $pics[0] $pics[1] and so on.. Then unset that specific var.

So if $pics[1] is the only one that is equal to default.gif then make it equal nothing and take it away.

So the foreach statement will not display the picture unless it is != default.gif

You need to loop through the array and check each key.

if ($pics[] == "default.gif") { unset($pics[]) }

foreach ($pics as $key => $value)
{

if ($value == "default.gif") { unset ($pics[$key]); } 

}
