PHP只显示$ value，直到$ value更改为止

Hi I have the following table that is generated from my database, it looks like this

The problem is I dont want the dates to repeat. If there is more than one fixture for a specific date, I only want the date displayed once and then the fixtures under the date.

Example In this case, on the image, Today,2015-04-23 must be displayed only once and then the 2 team names under it.

Im using the following code

$echoed = false;

while($row = > $played){

$gameDate = $row['event_date'];
$team1 = $row['team1'];
$team2 = $row['team2'];
$venue = $row['venue'];
$eventId = $row['event_id'];



    if($gameDate == $date && !$echoed){

    echo'<tr>'; 
    echo $echoed ='<td>Today,'.$gameDate.'echo</td>';
    echo'</tr>';
    echo'<tr>';
        echo'<td>'.$team1.'</td>';
        echo'<td>'.$team2.'</td>';
        echo'<td>'.$venue.'</td>';
        :
        :

However code above is not giving desired result and returns result same as per image above

You can check, if the date is the same as the one before:

<?php
$lastDate = '';

while($row = > $played){

$gameDate = $row['event_date'];
$team1 = $row['team1'];
$team2 = $row['team2'];
$venue = $row['venue'];
$eventId = $row['event_id'];
if($gameDate !== $lastDate) {
echo'<tr>';
  $lastDate = $gamedate;
  echo $echoed ='<td>Today,'.$gameDate.'echo</td>';
echo'</tr>';
}
echo'<tr>';
echo'<td>'.$team1.'</td>';
echo'<td>'.$team2.'</td>';
echo'<td>'.$venue.'</td>';

Note: i removed your echoed code and your if-statement, because $date is undefined :)

Save the last date in each loop and just check with date in current step.

$last_date = '';

while (...) {
    $gameDate = $row['event_date'];
    // set other variables

    if ($gameDate != $last_date) {
        // write $gameDate here
    }

    // teams table here    

    $last_date = $gameDate;
}

Instead of using $echoed the way you do, you can use the $date variable only to keep track of the current date you are printing for. Then you only print the date itself when it changes.

Something like:

// I am using $date as it seems undefined, but if you already use that, name it something else
$date = false;

while($row = > $played){

  $gameDate = $row['event_date'];
  $team1 = $row['team1'];
  $team2 = $row['team2'];
  $venue = $row['venue'];
  $eventId = $row['event_id'];

  if($gameDate !== $date){
    $date = $gameDate;
    echo'<tr>'; 
    echo $echoed ='<td>Today,'.$gameDate.'echo</td>';
    echo'</tr>';
  }
  echo'<tr>';
  echo'<td>'.$team1.'</td>';
  echo'<td>'.$team2.'</td>';
  echo'<td>'.$venue.'</td>';
