PHP variable debugging functions

[PHP] code

function ss_array_as_string (&$array, $column = 0) {$str = "Array(n";while(list($var, $val) = each($array)){for ($i = 0; $i < $column+1; $i++){$str .= "    ";}$str .= $var. '==>' ;$str .= ss_as_string($val, $column+1)." n";}for ($i = 0; $i < $column; $i++){$str .= "    ";}return $str.);}function ss_object_as_string (&$object, $column = 0) {if (empty($object－>classname)) {return "$object";}  else {$str = $object－>classname."( n";while (list(,$var) = each($object－>persistent_slots)) {for ($i = 0; $i < $column; $i++){$str .= "    ";}  　global $$var;  　$str .= $var. '==>' ;$str .= ss_as_string($$var, column+1)." n";}for ($i = 0; $i < $column; $i++){$str .= "    ";}return $str.')';}}function ss_as_string (&$thing, $column = 0) {if (is_object($thing)) {return ss_object_as_string($thing, $column);}　elseif (is_array($thing)) {return ss_array_as_string($thing, $column);}　elseif (is_double($thing)) {return "Double(".$thing.")";}  elseif (is_long($thing)) {return "Long(".$thing.")";}  elseif (is_string($thing)) {return "String(".$thing.")";}  else {return "Unknown(".$thing.")";}}

When necessary, simply add the following code to the program to view the types and values of the variables used in the program (including arrays and objects ).

echo ss_as_string($my_variable);

Using the following statement, we can directly view the values of all the variables in the program

echo ss_as_string($GLOBALS);
