Enum arrays

[dcr33]

<?php
$myarray = array(
 [0] => 'string a',
 [2] => 'string b',
 [4] => 'string c',
[8] => 'string d',
); 
$arraycount = count( $myarray );
for( $i = 0; $i < $arraycount; $i++ ) {
  echo  'key is: ' . $i . ' - value is ' . $myarray[$i] . '<br />';
}
?>

Why is the above code showing error as follows:
Parse error: syntax error, unexpected '[', expecting ')' in ....\xampp\htdocs\....\1.php on line 3

[djr33]

[8] => 'string d',

[dcr33]

But that is already in the code

[8] => 'string d',

Where is the error?

[djr33]

The last item in an array (or any other kind of comma separated list) must NOT have a comma, or it will cause an error.

By the way you're going to get a lot of warnings about undefined indices if you do it like that. You'd need to count by two in the for loop, or you could use a foreach loop, which is specifically designed for arrays.

Ya i intentionally put those indices like that. ;-) :-P But i removed the last comma still it i giving error

[dcr33]

I put it like this according to your suggestion@djr33,but still i get the same error!

<?php
$myarray = array(
 [0] => 'string a',
 [2] => 'string b',
 [4] => 'string c',
 [8]=> 'string d'); 
$arraycount = count( $myarray );
for( $i = 0; $i < $arraycount; $i++ ) {
  echo  'key is: ' . $i . '  value is ' . $myarray[$i] . '<br />';
}
?>

Oh, you don't put [] around array keys. That's just when it's being displayed to you (such as with the print_r() function), or when you are accessing an individual item from the array with $array[0] or $array['key'].

<?php
$myarray = array(
 0 => 'string a',
 2 => 'string b',
 4 => 'string c',
 8=> 'string d'); 
$arraycount = count( $myarray );
for( $i = 0; $i < $arraycount; $i++ ) {
  echo  'key is: ' . $i . '  value is ' . $myarray[$i] . '<br />';
}
?>

Please try the below code

<?php
$myarray = array(
0 => 'string a',
2 => 'string b',
4 => 'string c',
8 => 'string d',
);

foreach($myarray as $x=>$x_val)
{
echo 'key is: ' . $x . ' - value is ' . $x_val . '<br />';
}
?>
