Syntax Error on php echo - php

I am having trouble getting the URL to display correctly. This works now, but the link has " in front of the url. and yet the url link works fine
echo "<br>" . $result['text'] . " <em>(Contributed by: \"<a
href=\"http://example.com/portfolio?ID=$result[ID]\">" .
$result['display_name'] . "</a>" . ")</em>" . "<br>";


sigh:
echo '<br>' . $result['text'] . ' <em>(Contributed by: <a
href="http://example.come/portfolio?ID="'.$result['ID'].'">'.
$result['display_name'] .'</a>)</em><br>';

Empty parameter when passing through header location

I'm setting a variable based on an array. When I echo the variable it displays on the screen, however when I try to add it to a Header Location it doesn't show up in the URL of the next page - everything else does:
$myid = $selected_cat3[0]['id'];
Header("Location:/cat-dashboard/cat-results/?catID=" . $myid
. "&question1=" . $_GET['question1'] . "&question2=" . $_GET['question2']
. "&question3=" . $_GET['question3'] . "&question4=" . $_GET['question4']
. "&question5=" . $_GET['question5'] . "&question6=" . $_GET['question6']
. "&question7=" . $_GET['question7'] . "&question8=" . $_GET['question8']);
This is the generated url:
/cat-dashboard/cat-results/?catID=&question1=0&question2=3&q‌​uestion3=1&question4‌​=1&question5=1&quest‌​ion6=2&question7=1&q‌​uestion8=3
Am I doing something wrong? It doesn't show even if I use: $myid = "1";

php in header url error

I have just a quick question. i was using a normal html link tag to redirect to a paypal checkout page and it was working fine even when i had php inside the url. but when i was using it in a php header
the url cuts off where i enter the php.
header('location: https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=XXXX&lc=UK&item_name=<? echo $product . " " . $server ?>&amount=<? echo $xprice1; ?>%2e00&currency_code=GBP&button_subtype=services&no_note=0&bn=PP%2dBuyNowBF%3abtn_buynowCC_LG%2egif%3aNonHostedGuest');

You are placing the PHP code inside of the location redirect as a string. The code is not being evaluated as PHP.
Try this instead:
<?php
$url = "https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=XXXX&lc=UK&item_name=" . $product . " " . $server ."&amount=" . $xprice1 . "%2e00&currency_code=GBP&button_subtype=services&no_note=0&bn=PP%2dBuyNowBF%3abtn_buynowCC_LG%2egif%3aNonHostedGuest";
header('location: ' . $url);
Or, you could keep it in one line like so:
<?php
header('location: ' . "https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=XXXX&lc=UK&item_name=" . $product . " " . $server ."&amount=" . $xprice1 . "%2e00&currency_code=GBP&button_subtype=services&no_note=0&bn=PP%2dBuyNowBF%3abtn_buynowCC_LG%2egif%3aNonHostedGuest");

header('location: https://www.paypal.com/cgi-bin/webscr?cmd=_xclick&business=XXXX&lc=UK&item_name=<? echo $product' . " " . '$server ?>&amount=<? echo $xprice1; ?>%2e00&currency_code=GBP&button_subtype=services&no_note=0&bn=PP%2dBuyNowBF%3abtn_buynowCC_LG%2egif%3aNonHostedGuest');
This may solve your problem. Please dont forget to tick the answer right if it works.

How to add a variable to this?

I am using the following snippet. How do I add q=$k in the <a href url>?
<?php
echo '<a id=d href="'.$_SERVER['PHP_SELF'].'?pg='.($s+10).'">Next</a>';
?>

<?php
echo '<a id=d href="'.$_SERVER['PHP_SELF'].'?pg='.($s+10).'&q='.$k.'">Next</a>';
?>
Something like that?

echo '<a id=d href="' . $_SERVER['PHP_SELF'] . '?pg=' . ($s+10) . '&q=' . $k . '">Next</a>';

You can do this:
echo "<a id='d' href='" . html_entities("$_SERVER[PHP_SELF]?pg="
. urlencode($s + 10) . "&q=" . urlencode($k)) . "'>Next</a>";
I added suitable escaping for the URL parameter and HTML output: URL encoding for the URL GET parameters, and HTML entity replacement for the entire URL string.

How would you do a code-escape in PHP?

I have a huge list of stuff for a glossary ( about 17 pages worth ) that I have to put into an XML file. So I decided I'd use php to make it. My code works, except where ALL the XML code is, it doesn't show because it's trying to render it. Help?
$arg=explode("\n", $strang);
echo count($arg);
for ($i=0;$i<=count($arg);$i=$i+3)
{
echo "<word id='" . $arg[$i+1] . "'>";
echo "<desc>" . $arg[$i] . " - " . $arg[$i+2] . "</desc>";
echo "<pic></pic>";
echo "<audio></audio>";
}

I assume by render it you mean in your browser? If so, you'll need to escape the characters so they will be interpreted literally rather than as markup.
Check out htmlspecialchars and htmlentities

use CDATA construction:
echo "<desc><![CDATA[" . $arg[$i] . " - " . $arg[$i+2] . "]]></desc>";

If this is your entire script, fastest way would probably be to swap all of the <'s with <
$arg=explode("\n", $strang);
echo count($arg);
for ($i=0;$i<=count($arg);$i=$i+3)
{
echo "<word id='" . $arg[$i+1] . "'>";
echo "<desc>" . $arg[$i] . " - " . $arg[$i+2] . "</desc>";
echo "<pic></pic>";
echo "<audio></audio>";
}

correct way to echo a link with a onclick javascript function

my question is how I can echo this the right way
because the variable in the onclick function gives out a undefined error
$openchat="<a href='javascript:void(0)' onClick='return chatWith(" . $livenaam .")'>" . $livenaam . "</a><br>";
echo $openchat;
I want to use it in a loop to get a list off users online for the chat
Thanks, Richard

Looks like you are missing some quotes:
$openchat="<a href='javascript:void(0)' onClick='return chatWith(\"" . $livenaam ."\")'>" . $livenaam . "</a><br>";
or for increased security:
$openchat="<a href='javascript:void(0)' onClick='return chatWith(\"" . htmlspecialchars($livenaam,ENT_QUOTES) ."\")'>" . htmlspecialchars($livenaam,ENT_QUOTES) . "</a><br>";

Try this:
'' . htmlspecialchars($livenaam) . '<br>'
If json_encode is not available, try this:
'' . htmlspecialchars($livenaam) . '<br>'
