This is a PHP quircks (hu, no specialities).
If you use single quotes when you define a string, the $variable is not replaced.
It is only if you use the double quotes:
PHP Code:
$animal="fox";
$string1="the $animal jumps over the lazy dog";
//$string1 is now:
//the fox jumps over the lazy dog
$string2='the $animal jumps over the lazy dog';
//but $string 2 is now:
//the $animal jumps over the lazy dog
But, you can have single quotes in a string, and don't need to concatenate the variables if the "outer" delimiter of the string are double quotes.
In the case of sql queries, this is sensible
PHP Code:
//this is valid, and $email will be replaced by the content of the variable
$query="insert into signup(email,zip) values('$email','NA')";
//here, using the single quotes delimiter forces us to concatenate the variable to the string AND escape the query single quotes
$query='insert into signup(email,zip) values(\''.$email.'\',\'NA\')';
And if you must use an array indice in your string, then you must enclose it's declaration between { and }
PHP Code:
$animals['dog']='woolfy';
$query="insert into animals (name) values ('{$animals['dog']}');";
