PHP - Single vs Double Quotation Marks
Posted on May 1st, 2009 No commentsIn PHP you can use either single quotation marks or double quotation marks. Anything contained between single quotation marks will be treated literally and anything between double quotation marks will be interpreted. For example:
echo ‘Here is a variable and the variable is $var’;
would literally output: Here is a variable and the variable is $var
If you put this line between double quotation marks it would output the following:
Here is a variable and the variable is 15.
There is one case where you may need to alternate the use the single and double quotes. Look at the following example:
echo ‘I will be going on holiday shortly and I’m taking my laptop with me’;
You will notice that you have used the ‘ symbol three times so therefore it will give a parse error. In this case you will have to use the double quotes. By the way this can happen vice versa as well so be careful when using single and double quotes in sentences.
