Regarding passing php variable to another page via link

Question

I want to pass a php variable, which is store in $row['ID'] to another page so i can execute my sql query with the passed variable.

I have this line of code with me

<?php echo ("<td>" . "<a href='http://localhost/kinhock/delete.php?ID=$row['ID']'>" 
. "Delete" . "<td>"); ?>

However i am getting syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING)

I am not clear about the double quote and single quote position. Is there any other way to pass my php variable instead of using this?

Answer 1

就像

echo "<td><a href='http://localhost/kinhock/delete.php?ID=".$row['ID']."'>Delete<td>";

Answer 2

When you have an array variable with a quoted string, you have to put a block around it to get it to interpolate properly. Your entire string can be rendered like this, just using interpolation:

echo "<td><a href='http://localhost/kinhock/delete.php?ID={$row['ID']}'>Delete<td>"; 

Answer 3

Try this

<?php
echo "<td><a href='http://localhost/kinhock/delete.php?ID=".$row['ID']."'>Delete<td>";
?>

Answer 4

echo不使用（），就像这样

echo "<td>" . "<a href='http://localhost/kinhock/delete.php?ID=".$row['ID'].">" . "Delete" . "<td>");
