function key_implode(&$array, $glue) { $result = ""; foreach ($array as $key => $value) { $result .= $key . "=" . $value . $glue; } return substr($result, (-1 * strlen($glue))); } And the usage: $str = key_implode($yourArray, ",");
Here's how to get the first key, the last key, the first value or the last value of a (hash) array without explicitly copying nor altering the original array: '111', 'second' => '222', 'third' => '333'); // get the first key: returns 'first' print array_shift (array_keys ($array)); // get the last key: returns ...
You can use var_dump() function to display structured information about variables/expressions, including its type and value, or you can use print_r() to display information about a variable in a way that's readable by humans.
How to echo key and value of an array without and with loop $keys = array_keys($page); implode(',',$keys); echo $keys[0].' is at '.$page['Home'];
So, basically if you want to print out both keys and values you better use foreach() function over for() loop function. This example shows how to echo both the keys and values from an Array(); "Apple", "two"=>"Ball", "three"=>"Cat"); foreach($myarray as $key=>$val){ echo $key."-".$val."
"; } ?>

If you're using PHP 5.5+, you can use array_column(), like so: $result = array_column($foo, 'type'); If you want an array with numeric indices, use: $result = array_values(array_column($foo, 'type'));
To loop through and print all the values of an associative array, you could use a foreach loop, like this: Display all array items, keys and values: For a complete reference of all array functions, go to our complete PHP Array Reference.
array_values () returns all the values from the array and indexes the array numerically. The array. Returns an indexed array of values. Example #1 array_values () example. The above example will output: [0] => XL. [1] => gold. Found A Problem?
@bruciasse - The way that the server handles input arrays like this will vary from one web server to another (different OSes implement things differently when it comes to fine grained details like this), however every platform I have employed these techniques on is consistent within itself (i.e. the ordering is the same every time).
