时间输入验证/当我输入intime 10:30或9:30两者都被接受但在PHP中条件不正确

Question

foreach ( $period as $dt )
{
    $new=$dt->format("Y-m-d");
    $sql1=mysql_query("SELECT * FROM enginner_timesheet e, cz c
            WHERE e.enginner_name='$name'
               and c.fullname='$fullname'
               and e.date='$new' ");            
    $row2= mysql_fetch_array($sql1);

    $in_time=$row2["in_time"];
    // if the condition apply
    if ($in_time > "10:20")
          $in_time = "<font color='#FF0000'>" .$in_time. "</font>";
    //if the condition met than time font will be red

    echo "<td>".$in_time."-".$row2["out_time"]."-".$row2["other_details"]."</td>";
} 

I want to require if the condition is true than font text will be red but my output differs. The value is shown in red but 10:23 shows in red and 9:23 also shows in red.

Answer 1

try this way

if(strtotime($in_time)>strtotime("10:20"))
