I am calling a function that returns the an array. A for loop iteration gives the following output.
string(22) "text/xml;charset=UTF-8"
string(7) "chunked"
string(4) "gzip"
array(2) { ["Expect"]=> string(12) "100-continue" ["Content-Type"]=> string(48) "application/x-www-form-urlencoded; charset=utf-8" }
object(CFSimpleXML)#10 (1) { [0]=> string(6) "123456" }
How can i check whether an array element is an object or string ?
foreach ($array as $element) {
if (is_array($element)) {
// array
} else if (is_string($element)) {
// string
} else if (is_int($element)) {
// int
} else if (is_float($element)) {
// float
} else if (is_bool($element)) {
// bool
} else if (is_object($element)) {
// object
} else if (is_resource($element)) {
// resource
} else {
// null/invalid type (you could add an === NULL if you want, I suppose)
}
}
There is also get_type() and the typeof operator, but since these return strings that may be subject to change in some future PHP version, the is_*() functions are more reliable.
You can get list of array elements types by this way
$types = array_map('gettype', $array);
I prefer the switch-trick solution:
foreach ($array as $element) {
switch(true)
{
case is_array($element):
// array
break;
case is_string($element):
// string
break;
case is_int($element):
// int
break;
case is_float($element):
// float
break;
case is_bool($element):
// bool
break;
case is_object($element):
// object
break;
case is_resource($element):
// resource
break;
default:
// null
}
}
if (is_object($arrayElement)) ...
if (is_array($arrayElement)) ...
if (is_string($arrayElement)) ...
Use is_array() https://www.php.net/manual/en/function.is-array.php; is_string() https://www.php.net/manual/en/function.is-string.php and is_object() https://www.php.net/manual/en/function.is-object.php functions.
You can use PHP gettype function, and then do required operations in a simple switch case code.
http://php.net/manual/en/function.gettype.php
see here : http://codepad.org/LRJcrKjJ
<?php
$data = array(1, 1.,'hello', NULL, new stdClass);
foreach($data as $item)
{
$currType = gettype($item);
switch($currType){
case "integer" :
echo "I am integer ".$item." , double of me = ".($item*2)."\n";
break;
case "string" :
echo "I am string ".$item." , reverse of me = ".strrev($item)."\n";
break;
default:
echo "I am ".$currType ."\n" ;
break;
}
}
?>
