value="<?php echo $product["name"] ?>" or value="<?php echo $product['name'] ?>" which is true " " or ' ' ?

my main doubt with the " "(double) quotes and ' '(single) quotes

3 Answers

in general the only difference is var names inside " are processed. So ["key_$id"] or ['key_'.$id]

Hi Prakhar Patwa .

As Guan Wu said the main difference with single and double quotes is that if you have a variable name in a double quotes then the variable will be evaluated and parsed - and if you use a single quote then the literal string will be used.

Both Guan and Nejc are correct. I am only writing to elaborate.

$name = 'Ted';

echo "My name is $name.";
// returns: My name is Ted.

echo 'My name is $name.';
// returns: My name is $name.

In the context of your question, you must use single quotes around name because you have the entire block enclosed by double quotes. If you use double quotes, it would be interpreted as this:

value="(open quote)<?php echo $product["(close quote)name"(open quote)] ?>"(close quote)
