php Challenged


Recommended Posts

Where $key and $item are valid text variables containing valid values, Why does this work?

echo "$key. $item<br />\n";

I thought the correct code would be

echo $key . $item . "<br />\n";

Is php responding to the $ to render the value of the variable even when it is within quotes? I thought that by being in quotes, it would render the literal value of what is quoted, and not the variable content.

why it works well, just becouse it is the right way to use it, you chould use :

echo"$key . $item .\"<br>\n\""; //but why do you have the \n actually? <br> works just fine dont it?

Dont actually understand what the whole challenge thing was about :)..-Kristian_C
