in_array() fails but it's in the array

[Phil Powell]

array_keys($boolword) = Array ( [0] => 'album' [1] => 'keywords' [2]
=> 'persons' [3] => 'events' [4] => 'image_alt' [5] =>
'image_creation_start_date' [6] => 'image_creation_end_date' [7] =>
'image_location_city' [8] => 'image_location_state' [9] =>
'image_location_country' )

Here is my array. Plain and simple enumerative array with values
being strings.

So why does this fail???

[PHP]
print_r(in_array('album', array_keys($boolword)));
[/PHP]

This produces FALSE or NULL. But it's right there IN the array!! What
on earth is going on? Is this a failure in the part of in_array() that
I am unaware of?

This is a major showstopper in my search code PHP script I'm writing
for my application, please help someone!

Thanx
Phil

have you tried with the proper syntax?

array_keys($boolword) = Array ( [0] => 'album',
[1] => 'keywords',
[2] => 'persons',
[3] => 'events',
[4] => 'image_alt',
[5] => 'image_creation_start_date',
[6] => 'image_creation_end_date',
[7] => 'image_location_city',
[8] => 'image_location_state',
[9] => 'image_location_country' );

What is $boolword ? it's inconsistent here, just place the name of the
array as second arg : print_r(in_array('album', array_keys));

You probably mean something like this:

$boolword = array('album', 'keywords', ...);

var_dump(in_array('album', $boolword));

No, sorry I meant exactly this:

$html .= "<select name=\"boolword['album']\">\n";
....
 

And to handle it I would parse $_POST out to get $boolword and you get
this:

print_r($boolword);
 

Results:

Array ('album' => 'AND', 'location' => '', 'image_name' => 'OR',
'whatever' => '')

Sorry I wasn't more clear. $boolword will be an associative array
whose keys are string values that are dynamically generated from the
name of the HTML form dropdown element 'boolword[something]'; the
value being a boolean word.

Problem is this: If I try to reference $boolword[$elementName] where
$elementName = 'album', it fails:

print_r($boolword[$elementName]);
 

Results: NULL

However, if I reference $boolword["'$elementName'"] where $elementName
= 'album', it works perfectly:

print_r($boolword["'$elementName'"]);
 

Results: AND

This is what I'm trying to convey. The associative array $boolword
produces an array where the keys seem to have embedded single quotes
inside the keys themselves!! Is this a PHP bug?

No, it's because you put the single quotes in the HTML. If you want to
use [] syntax to get an array into $_REQUEST, you can either do this:

<select name="boolword[]">

for a numeric array $_REQUEST['boolword'], or this:

<select name="boolword[album]">

for an associative array $_REQUEST['boolword']. You shouldn't quote the
array key in the HTML. Quoting array keys is only needed in PHP code.
