PHP MYSQL<？php echo $ row [$ variable]; ？> [英] PHP MYSQL <?php echo $row[$variable]; ?>
问题描述
我有以下代码可以实现我想要的功能，但是反斜杠<？php echo $ row [\’t_id\’]; ？> ，<？php echo $ row [\’t_type\’]; ？> 和<？php echo ucfirst $ row [\'t_fn\']）。\'& nbsp; \'.ucfirst（ $ row [\'t_ln\']）; ？> 不输出它们各自的变量。
I have the following code that does what I want it to do, but the ones with the backslashes <?php echo $row[\'t_id\']; ?>, the <?php echo $row[\'t_type\']; ?> and the <?php echo ucfirst$row[\'t_fn\']).\' \'.ucfirst($row[\'t_ln\']); ?> do not output their respective variable.
相反，它们的输出像
view_t_profile.php?tutor_id=<?php echo $row['t_id']; ?>&t_type=<?php echo $row['t_type']; ?>
<？php echo ucfirst $ row ['t_fn']） 。'& nbsp;'。ucfirst（$ row ['t_ln']）; ？> 不会像以前的代码那样显示在网页上，而是以斜体显示为红色文本。我不是程序员，所以如果有人可以更正我的代码，我肯定会感激的。通常，我可以弄清楚，但是在这一点上，我不知道。
The <?php echo ucfirst$row['t_fn']).' '.ucfirst($row['t_ln']); ?> doesn't show up on the web page like the previous code, but its in the code italicized and in red text. I'm not a programmer/coder, so if someone can correct my code, I sure would appreciate it. Usually, I can figure it out, but on this one, I cannot.
<?php
if($row['t_type'] == 1)
{
echo '<center><strong><font color="#3BB9FF"><a href="view_t_profile.php?t_id=<?php echo $row[\'t_id\']; ?>&t_type=<?php echo $row[\'t_type\']; ?>" class="cls" target="_blank"><br />View Profile</a></font></strong></center>';
echo '<center><strong>Main Contact</strong></center>';
echo '<center><strong><font color="#3BB9FF"><?php echo ucfirst$row[\'t_fn\']).\' \'.ucfirst($row[\'t_ln\']); ?></font></strong></center>';
}
if($row['t_type'] == 0)
{
echo '<center><strong><font color="#3BB9FF"><a href="view_t_profile.php?t_id=<?php echo $row[\'t_id\']; ?>&t_type=<?php echo $row[\'t_type\']; ?>" class="cls" target="_blank"><br />View Profile</a></font></strong></center>';
echo '<center><strong>Main Sponsor</strong></center>';
echo '<center><strong><font color="#3BB9FF"><?php echo ucfirst$row[\'t_fn\']).\' \'.ucfirst($row[\'t_ln\']); ?></font></strong></center>';
}
?>
推荐答案
您不使用 <？php echo ...？> 当您已经处于PHP模式并回显某些内容时。只需连接变量即可。
You don't use <?php echo ... ?> when you're already in PHP mode and echoing something. Just concatenate the variable.
echo '<center><strong><font color="#3BB9FF">' . ucfirst($row['t_fn']) . ' ' . ucfirst($row['t_ln']) . '</font></strong></center>';
<？php echo ...？> 在您仅直接输出HTML并想要插入一些PHP时使用。例如，像这样：
<?php echo ... ?> is used when you're just outputting HTML directly, and you want to insert a bit of PHP. For instance, like this:
if($row['t_type'] == 1)
{ ?>
<center><strong><font color="#3BB9FF"><a href="view_t_profile.php?t_id=<?php echo $row['t_id']; ?>&t_type=<?php echo $row['t_type']; ?>" class="cls" target="_blank"><br />View Profile</a></font></strong></center>
<center><strong>Main Contact</strong></center>
<center><strong><font color="#3BB9FF"><?php echo ucfirst$row['t_fn']).' '.ucfirst($row['t_ln']); ?></font></strong></center>
<?php
}
