How do I check if a multi-dimension array has a value.

[jamesxg1]

Hiya!

 

I was wondering if there is a way to check if an array has values EG.

 

array('ONE' => 'ONE', 'TWO');

 

ONE = TRUE

TWO = FALSE

 

How would I then filter out that array key TWO does not have a value?

 

Many thanks

TWO is not array array index in your example. It is the value at index 1.

TWO is not array array index in your example. It is the value at index 1.

 

Confused LOL :S.

 

What I'm building involves me to insert and array like the one I provided into a class but it will not work if there is a missing value (Like TWO), so what I need to do is filter the whole array, maybe if I filter for numeric's ?

 

This is my code.

 

<?php session_start();

class template {

private $tags = array();

	function newTemplate($tags) {

		if(!is_array($tags) OR !is_dir('./assets/templates/') OR !file_exists('./assets/templates/global.html') OR !is_file('./assets/templates/global.html') OR !file_exists('./assets/templates/error.html') OR !is_file('./assets/templates/error.html') OR !is_readable('./assets/templates/error.html') OR !is_readable('./assets/templates/global.html')):
			exit('<center>Sorry for inconvenience but our system has located an error due to this the site is now shutdown.</center>');
		else:
			$keys = array_keys($tags);
			$del = array();
			$tagcheck = array('ONE');
			$file = file_get_contents('./assets/templates/global.html');

			if(!$file OR !is_array($tagcheck)):
				exit('<center>Sorry for inconvenience but our system has located an error due to this the site is now shutdown.</center>');
			else:

				foreach($tags as $item => $itemvalue):
					if(!in_array($item, $keys, true)):
						$del[] = '/{' . $item . '}/';
					endif;
				endforeach;

				foreach($keys as $key => $value):
					$keys[$key] = '{' . $value . '}';
				endforeach;

				$file = preg_replace($del, '', $file);

				echo str_replace($keys, $tags, $file);

			endif;
		endif;

	}
}
?>

 

Many thanks

So, you want to check if the array is an associative array?

 

function is_assoc($array) {
    return (is_array($array) && 0 !== count(
        array_diff_key(
            $array, array_keys(
                array_keys($array)
            )
        )
    ));
}

Cheers mate, just wondering how I use it LOL?

 

Many many thanks

Could I do this?

 

if(count(array_keys($array)) == (is_array($array) && 0 !== count(array_diff_key($array, array_keys(array_keys($array)))))) {
// good
} else {
// bad
}

 

Many thanks

function is_assoc($array) {
    return (is_array($array) && 0 !== count(
        array_diff_key(
            $array, array_keys(
                array_keys($array)
            )
        )
    ));
}

$arr = array('ONE' => 'ONE', 'TWO');
echo is_assoc($arr) ? 'is assoc' : 'is not assoc';

[jamesxg1]

Still not much luck mate,

 

$array = array('ONE', 'TWO' => 'TWO');

function is_assoc($array) {
    return (is_array($array) && 0 !== count(
        array_diff_key(
            $array, array_keys(
                array_keys($array)
            )
        )
    ));
}

echo is_assoc($array) ? 'is assoc' : 'is not assoc';

 

echo's; is assoc

 

Many thanks

I might not quite be understanding what you want to get out of this but here's an idea.

 

$array = array('ONE' => 'ONE', 'TWO');
foreach ($array as $key => $value) {
    if (is_int($key)) {
        unset($array[$key]);
    }
}

// See what is in the array
print_r($array);

Stunning! Worked like a charm thanks your all your help guy's.

 

Many thanks
