in_array() -- 我做错了什么？

Question

I'm banging my head against the wall here.

I have some simple code that goes something like this (I've simplified it greatly for simplicity's sake):

$myValue = 1;

$myArray[0] = 2;
$myArray[1] = 3;
$myArray[2] = 1;

if(in_array($myValue, $myArray, true)) {
   do something;
}
else {
   do something else;
}

I always get the 'else.' Am I doing something wrong here?

Answer 1

It will return "Yes". Do & else are PHP keyword. Echo Something.. It Will Come

<?
$myValue = 1;

$myArray[0] = 2;
$myArray[1] = 3;
$myArray[2] = 1;

if(in_array($myValue, $myArray, true)) 
{
   echo "Yes";
}
else 
{
   echo "No";
}
?>

Otherwise, if you use 'do' or 'else' keyword, Parse error: syntax error, unexpected '}', expecting while (T_WHILE) error will come.
