Php print array pretty

print_r

print_r() выводит информацию о переменной в удобочитаемом виде.

print_r() , var_dump() и var_export() могут также показывать защищенные (protected) и закрытые (private) атрибуты объектов в PHP 5. Статические элементы класса не будут отображены.

Список параметров

Выражение для вывода на экран.

Если вы хотите перехватить вывод print_r() , используйте параметр return . Если его значение равно TRUE , то print_r() вернет результат вывода вместо вывода в браузер (который производится по умолчанию).

Возвращаемые значения

Если в функцию передаются значения типов string , integer или float , будет напечатано само значение. Если передается массив array , значения будут напечатаны в формате, показывающем ключи и элементы массива. Аналогичный формат вывода используется для объектов.

Если параметр return установлен в TRUE , данная функция вернет строку ( string ). В противном случае возвращаемое значение будет равно TRUE .

Примечания

Замечание:

При использовании параметра return данная функция использует внутреннюю буферизацию вывода, поэтому она не может быть использована внутри callback-функции ob_start() .

Примеры

Пример #1 Пример использования print_r()

 
$a = array ( 'a' => 'apple' , 'b' => 'banana' , 'c' => array ( 'x' , 'y' , 'z' )); 
print_r ( $a ); 
?> 

Результат выполнения данного примера:

 
Array ( [a] => apple [b] => banana [c] => Array ( [0] => x [1] => y [2] => z ) )
 
Пример #2 Пример использования параметра return 
 
$b = array ( ‘m’ => ‘monkey’ , ‘foo’ => ‘bar’ , ‘x’ => array ( ‘x’ , ‘y’ , ‘z’ )); 
$results = print_r ( $b , true ); // $results теперь содержит вывод print_r 
?>

php print_r nice table
 
I’m looking to be able to produce a nicely formatted table with rows and columns from the contents of a print_r array statement? Any ideas?
 
What do you define as «nicely formatted»? Do you want an HTML table? Some XML? JSON? CVS? Human-readable plaintext?
 
Instead of using print_r just use a foreach on the array, as jasondavis suggests, below. Also, in line with strager’s comment, I’d echo the request for a specific request/question. It would help, at the least, to know what’s in the array, is it one, two, three dimensional.

Here is a very simple way to print pretty arrays with html pre tag:
 
Or this one-liner: echo «
 
" . print_r($myarray, true) . "
 
«;
 
Your question is a bit vague, but did you mean something like this:
 
 
Try this out, could be improved but it works.
 
function myprint_r($my_array) < if (is_array($my_array)) < echo ""; echo ''; foreach ($my_array as $k => $v) < echo '"; > echo "
ARRAY
'; echo '' . $k . "
"; myprint_r($v); echo "
"; return; > echo $my_array; > 
 
How can you adapt this function so it returns a final built up string instead of printing the table out?
 
@user3574492: Drop the echo lines and store it into a variable instead with concatenation. Then have function return the variable.
 
Here is another nice example that I found. Same output, longer code, little bit more color.
 
function print_nice($elem,$max_level=10,$print_nice_stack=array())< if(is_array($elem) || is_object($elem))< if(in_array(&$elem,$print_nice_stack,true))< echo "RECURSION"; return; > $print_nice_stack[]=&$elem; if($max_level<1)< echo "nivel maximo alcanzado"; return; > $max_level--; echo ""; if(is_array($elem))< echo ''; >else< echo ''; > $color=0; foreach($elem as $k => $v)< if($max_level%2)< $rgb=($color++%2)?"#888888":"#BBBBBB"; >else < $rgb=($color++%2)?"#8888BB":"#BBBBFF"; >echo '"; > echo "
ARRAY
'; echo 'OBJECT Type: '.get_class($elem).'
'; echo ''.$k."
"; print_nice($v,$max_level,$print_nice_stack); echo "
"; return; > if($elem === null)< echo "NULL"; >elseif($elem === 0)< echo "0"; >elseif($elem === true)< echo "TRUE"; >elseif($elem === false)< echo "FALSE"; >elseif($elem === "")< echo "EMPTY STRING"; >else< echo str_replace("\n","*
\n",$elem); >
