Where is the problem in this PHP code?

There is a problem in this code I can not detected

<?php echo "<a href ='$rows['Link']'> .$rows['UploadName']</a> "; ?>

Do you find you have a s开发者_如何学JAVAolution???

My guess is that your problem is that it isn't writing out the data in $rows['Link'] ... if that is the case, then your solution is to change it to {$rows['Link']} ... actually, you'll probably want to change both, since it looks like you started doing string concatenation and then switched halfway through.

So:

<?php echo "<a href ='$rows['Link']'> .$rows['UploadName']</a> "; ?>

becomes:

<?php echo "<a href ='{$rows['Link']}'>{$rows['UploadName']}</a> "; ?>

See: The PHP Manual on Variable Parsing in strings

It should be:

<?php echo "<a href ='{$rows['Link']}'>{$rows['UploadName']}</a>"; ?> 

Or:

<?php echo "<a href ='{$rows['Link']}'>" . $rows['UploadName'] . "</a>"; ?>

There's a problem in parsing variables in the string. Use curl braces:

<?php echo "<a href ='{$rows['Link']}'> .{$rows['UploadName']}</a> "; ?>

Take a look to this php.net page, under "variable parsing".

More alternatives:

<?php echo '<a href ="' . $rows['Link'] . '">' . $rows['UploadName'] . '</a>'; ?>

or

<?=('<a href ="' . $rows['Link'] . '">' . $rows['UploadName'] . '</a>')?>

Another alternative (that I tend to prefer, given I know that both 'Link' and 'UploadName' are valid indices of $row.

<a href="<?=$rows['Link']?>"><?=$rows['UploadName']?></a>

I'm not sure what that does for readability for most people, but on color-coded IDEs, it tends to help, because the HTML isn't just seen as one giant ugly single-colored string.
