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

Accepted Answer

PHP performs type juggling during arithmetic operations. The string '5' is cast to an integer 5, resulting in 15. The concatenation operator (.) has lower precedence than the addition operator (+), so the addition occurs first. The integer 15 is then converted to a string and concatenated with '5', resulting in '155'.
