I am facing some problem in PHP code. It is a basic question but I don't know the answer. The code is here:
echo '<a href="profile.php?act=show&id=<?=$_SESSION['id']?>&line=true" class="myac">My Data</a>';
How to use the quotation mark in the id? Please help me.
That's wrong. Already you are using echo. So concatenate the value this way:
<?php
echo '<a href="profile.php?act=show&id=' . $_SESSION['id'] . '&line=true" class="myac">My Data</a>';
//-------------------------------------^^^^^^^^^^
And please refrain from using short tags (<? ?>), use full tags: <?php ?>.
apart from the above mentioned way by @praveen u can use it like below also if u don't want to put the anchor tag inside php
<a href="profile.php?act=show&id=<?php echo $_SESSION['id']?>&line=true" class="myac">My Data</a>
