Multi-line comments start with /* and end with */.
/*
*/
Any text between /* and */ will be ignored.
The following example uses a multi-line comment as an explanation:
Multi-line comment as an explanation:
/* The next statement will print a welcome message */ echo "Welcome Home!";
We can use multi-line comments to prevent blocks of code from being executed:
Multi-line comment to ignore code:
/* echo "Welcome to my home!"; echo "Mi casa su casa!"; */ echo "Hello!";
The multi-line comment syntax can also be used to prevent execution of parts inside a code-line:
The + 15 part will be ignored in the calculation:
+ 15
$x = 5 /* + 15 */ + 5; echo $x;
Use the PHP multi-line comment syntax to make sure the following code lines are not executed:
x = 5; print(x);
