Re: [PHP] hello the list
Welcome Nicolas,
=You didn't actually say what the problem was!
=Some have made suggestions, please also consider (below):
i'm new and i'm trouble with this code :'( can U help me please ??
this is the code :
while ($cd_tbl = mysql_fetch_array ($result))
{
$cd_id = $cd_tbl['cd_id'];
$cd_oeuvre = $cd_tbl['cd_oeuvre'];
$cd_chef = $cd_tbl['cd_chef'];
$cd_compositeur = $cd_tbl['cd_compositeur'];
---partie concernée-
//-Debut Seth
//--
// name : _ALTERNANCE_COULEUR_
// desc : test de 'id' pour l'alternance de couleur
//--
if(is_int($cd_id) = TRUE)
=there is no need for the double-quotes in this statement.
=you should be coding equality (==) or even equality and type equivalence
(===)
Regards,
=dn

Strings work differently when the outer quotes are double or single quotes.
Inside double quotes variables will be converted into their values. Inside
single they will not.
So:
$var = 'Hello World';
echo $varbr\n;
will result in
Hello Worldbrnewline
and:
$var = 'Hello World';
echo '$varbr\n';
will result in
$varbr\n //actual two characters '\' and 'n' and not newline.
Inside double or single quotes, you can use the other quote:
$var = 'Hello World';
echo $varbr\n;
Hello Worldbrnewline
$var = Hello 'World';
echo $varbr\n;
Hello 'World'brnewline
Your trouble is that you're using double quotes inside a double quoted
string and the second double quote that php encounters will terminate the
string. The next thing encountered is your variable $bgcolor, but that
syntax isn't correct. php sees your string as three pieces:
1. td bgcolor=
2. $bgcolor
3. font face=Verdana size=1b$cd_id/b/font/td;
So you could either convert the double quotes inside the string into single
quotes:
echo td bgcolor='$bgcolor'font face=Verdana
size=1b$cd_id/b/font/td;
or escape the double quotes like this:
echo td bgcolor=\$bgcolor\font face=Verdana
size=1b$cd_id/b/font/td;
or you could concatenate the three pieces:
echo td bgcolor= . $bgcolor .font face=Verdana
size=1b$cd_id/b/font/td;
I personally like all of the tag values double quoted so I'd
echo td bgcolor=\$bgcolor\font face=\Verdana\
size=\1\b$cd_id/b/font/td;
When php parses the outside double quoted string, it has to do extra work to
convert variables. I generally use single quotes unless there's a variable
or special char to convert (like newline). It doesn't really matter though,
it's fast anyway.
If your using arrays inside a double quoted string, you need to help php out
and use special coding. This code won't work:
$arr = array('fish' ='Tuna','reptile' = 'Snake','rodent' = 'mouse');
echo $arr['fish']br\n;
This will work:
$arr = array('fish' ='Tuna','reptile' = 'Snake','rodent' = 'mouse');
echo {$arr['fish']}br\n; // note the curly braces around the array
