urlencode php示例

Question

I want to pass a php variable as part of the link. How can I achieve this?

$x = 24; //$x is a php variable 

How to pass this value as part of a href="". A working example would be helpful.

Answer 1

<A href="whatever.php?x=<php echo $x;?>">link</a>

Answer 2

It works mostly like the version you know from Javascript:

print '<a href="page.php?x=' . urlencode($x) . '&y=2">click here</a>';

Or if you want to use the PHP inline html notation style (with short tags <?= enabled):

<p><a href="page.php?x=<?= urlencode($x) ?>">click here</a></p>

Answer 3

$x = 24;
$y = 'some text';
print('<a href="http://site.com/url.php?x=' . rawurlencode($x) . '&amp;y=' . rawurlencode($y) . '"></a>');

in url.php file you can get this variables using

$x = $_GET['x'];
$y = $_GET['y'];

Answer 4

Use http_build_query() to build query string ( a=b&c=d ). This function handles all typical probles like escaping (eg. # → %23 ) or proper HTML mark-up ( & → & ) etc.

printf('<a href="http://site.com/url.php?%s">Click me</a>', http_build_query(array(
   'a' => $x,
   'b' => 'Some strange characters like #$^$%&%^*^&('
)));
