What is the output of the following code snippet? $a = ’10’; echo $a + 5;

Accepted Answer

PHP performs type juggling when an arithmetic operator is applied to a string containing a numeric value. The string '10' is implicitly converted to the integer 10, allowing the addition operation to result in 15. It does not perform string concatenation, which is reserved for the dot (.) operator.
