Trying to figure out how to do the equivalent of something I did in javascript but in php. But I'm not sure of the operators to do it. In javascript I wanted to see if a particular parameter being passed was either an object or array.. and if not then was it a string/int and what I did was something like
if (str instanceof Array || str instanceof Object)
{
//code
}
else
{
//code
}
anyone know of the equivalent to this for php?
Use is_array to check if a variable is an array, and similarly, use is_object to check if a variable is an object.
json_decode it, and if it fails, it's not JSON.
is_array($var) turns out to be your bottleneck after profiling then (array) $var === $var is more performantTry to use:
if (!is_scalar($var)) {
// Varible is object or array
}
From PHP 8.1 and above, you can use:
array_is_list($array)
https://www.php.net/manual/en/function.array-is-list.php
Pure is_array/is_object is unable to judge because:
is_array([0,1,2,3]) // true
is_object([0,1,2,3]) // false
is_array(['a'=>1,'b'=>2]) // true
is_object(['a'=>1,'b'=>2]) // false
Here i wrote a simple function to do it
function isRealObject($arrOrObject) {
if (is_object($arrOrObject))
return true;
$keys = array_keys($arrOrObject);
return implode('', $keys) != implode(range(0, count($keys)-1));
}
implode() glue can be omitted when an empty string is the desired glue. It seems that you've posted on the wrong page. stackoverflow.com/q/173400/2943403 already covers the topic that you are trying to cover.I came across this question while looking for is_countable. Maybe it's of some use to somebody.
https://www.php.net/manual/en/function.is-countable.php
stdClass Object
(
[rest_food_items_id] => 137
[rest_user_id] => 42
)
array (use is_array)----
Array
(
[rest_food_items_id] => 137
[rest_user_id] => 42
)

if(is_object($data)){
}
if(is_array($data)){
}
As of PHP 8.0, you can use Union types when writing functions, validating your paramter's type at runtime:
function test(array|object $something): void
{
// Here, $something is either an array or an object
}
else branch to handle non-array/non-object data.
