PHP - Troubled With Quotes

This code only works in firefox
<a onMouseout='hidetooltip()' onMouseover='tooltip(\"<img src=img/heroes/$hero.gif\")' href='hero.php?hero=$hero'>Text</a>
Btw, I use this in echo (php).
How to get quotes (triple) on <img src=
?
I also have tried
<img src='img/heroes/$hero.gif'
But only works on FireFox

Hi, I could really do with some help putting the prices from two drop down boxes into sessions


To start with the user can choose two seats one from each drop down box

//DROP DOWN BOX ONE
$extract =mysql_query("SELECT * FROM ride WHERE rideID ='1'");
$numrows = mysql_num_rows($extract);
//start of form
echo '<form method="post" name="f1" action="card.php">';
echo 'Please choose a seat:  '; 
echo"<select name='seat' >";
while( $row = mysql_fetch_assoc($extract)) 
{   
$rideID = $row ['rideID'];
$name = $row ['name'];
$seatNumber = $row ['seatNumber'];
$time = $row ['time'];
$price = $row ['price'];

echo "<option name='seat'> $seatNumber </option>";
$_SESSION['extract']=$_POST['seat'];
}  
echo '</select><br>'; 

//DROP DOWN BOX TWO
$extract2 =mysql_query("SELECT * FROM ride WHERE rideID ='1'");
$numrows = mysql_num_rows($extract2);
//start of form
echo '<form method="post" name="f2" action="card.php">';
echo 'Please choose a seat:  '; 
echo"<select  name='seat2' >";
while( $row = mysql_fetch_assoc($extract2)) 
{   
$rideID = $row ['rideID'];
$rideName = $row ['rideName'];
$seatNumber = $row ['seatNumber'];
$time = $row ['time'];
$price = $row ['price'];

echo "<option name='seat2'> $seatNumber </option>";
$_SESSION['extract2']=$_POST['seat2'];
}  
echo '</select><br>'; 




at the moment I have this :

$query =mysql_query("SELECT price FROM ride WHERE rideID ='1' LIMIT 1");
while ($row=mysql_fetch_array($query))
{
echo $row['price'];
echo "<br>";

                $seatPrice1=($row['price']);
        $seatPrice2=($row['price']*2);


$vat1=17.5;

function vat($vat, $row['price'])
{
return sprintf("%01.2f", ($vat*$row['price]/ 100));
}
$vatprice = vat(17.5, 2.50);

                $total1=($vatprice);
$total2=($vatprice*2);

$endPrice1= ($total1+$seatPrice1);
$endPrice2= ($total2+$seatPrice2);



What I need is $endPrice1 and $endPrice2 in $_SESSIONS so i an INSERT them in to the database 3 pages away from this query/VAT fucntion.

Can anyone help?

Quotation marks are confusing me.   What do you guys use when it comes to quotation marks?   In HTML attributes and throughout the bodies of my web pages, I use the HTML entity (&quot;). For example:

<a href="" title="Read &quot;Article Name&quot;">

<p>In his new book, he says: &quot;This is a quote.&quot;</p>

I thought that this is the best practice.   However, today, I read that it's perfectly safe to use straight quotes (") in the body, and that I should use the HTML entity only in HTML attributes.   Is that correct?   But what if I want to use curly quotes in the body instead of straight quotes? Should I always use the HTML entities for curly quotes (&ldquo; and &rdquo;), or can I also safely use the characters (“”)?   I heard that straight quotes are safe in all browsers, even if you don't specify the character set of your web pages, but that curly quotes are only safe if you specify the character set or if you use the HTML entities.   Is that true?   And what about the <q> tag? Apparently, it's compatible with all browsers but they treat it differently.

The fancy-looking quotes won't insert into my DB, so I'm trying to convert them to %93 & %94 or normal quotes.    Nothing I've tried works.   Code:   $fancy=" “test” ";
$fixed=htmlentities($old, ENT_QUOTES);   echo "fancy: $fancy<br>"; echo "fixed: $fixed";

Results:

fancy: “test”
fixed:   I want $fixed to be %93test%94, or even "test" would work.

Hello everyone!  This is my first post.  I am very new to php and mysql and coding in general.  It has not been made 100% clear to me as to when I should use single quotes, double quotes, and {}.  From what I gather you use single quotes for literal interpretation...  so if you put something like a variable in single quotes and echoed it, it would literally echo it as it is written and not the value of the variable.  in double quotes, I gather that it will echo the value of the variable.  as for {} I am unclear as to when to use the curly brackets for a variable.  I am assuming if you had a statement in single quotes and you put a variable in curly brackets you would get the value of the variable?
