final class PhutilReadableSerializer
libphutil Technical Documentation ()

Serialize PHP values and objects into a human-readable format, useful for displaying errors.

Tasks

Printing PHP Values

public static function printableValue($value) — Given a value, makes the best attempt at returning a string representation of that value suitable for printing. This method returns a //complete// representation of the value; use @{method:printShort} or @{method:printShallow} to summarize values.
public static function printShort($value) — Print a concise, human readable representation of a value.
public static function printShallow($value, $max_depth, $max_members) — Dump some debug output about an object's members without the potential recursive explosion of verbosity that comes with `print_r()`.

Internals

private static function printShallowRecursive($value, $max_depth, $max_members, $depth, $indent) — Implementation for @{method:printShallow}.
private static function addIndentation($value, $indent, $first_line) — Adds indentation to the beginning of every line starting from `$first_line`.

public function getPhobjectClassConstant($key, $byte_limit)
Inherited

Phobject

Read the value of a class constant.

This is the same as just typing self::CONSTANTNAME, but throws a more useful message if the constant is not defined and allows the constant to be limited to a maximum length.

Parameters

string	$key	Name of the constant.
int\|null	$byte_limit	Maximum number of bytes permitted in the value.

Return

string

Value of the constant.

public static function printableValue($value)

Given a value, makes the best attempt at returning a string representation of that value suitable for printing. This method returns a complete representation of the value; use printShort() or printShallow() to summarize values.

Parameters

wild

$value

Any value.

Return

string

Human-readable representation of the value.

public static function printShort($value)

Print a concise, human readable representation of a value.

Parameters

wild

$value

Any value.

Return

string

Human-readable short representation of the value.

public static function printShallow($value, $max_depth, $max_members)

Dump some debug output about an object's members without the potential recursive explosion of verbosity that comes with print_r().

To print any number of member variables, pass null for $max_members.

Parameters

wild	$value	Any value.
int	$max_depth	Maximum depth to print for nested arrays and objects.
int	$max_members	Maximum number of values to print at each level.

Return

string

Human-readable shallow representation of the value.

private static function printShallowRecursive($value, $max_depth, $max_members, $depth, $indent)

Implementation for printShallow().

Parameters

wild	$value	Any value.
int	$max_depth	Maximum depth to print for nested arrays and objects.
int	$max_members	Maximum number of values to print at each level.
int	$depth	Current depth.
string	$indent	Indentation string.

Return

string

Human-readable shallow representation of the value.

private static function addIndentation($value, $indent, $first_line)

Adds indentation to the beginning of every line starting from $first_line.

Parameters

string	$value	Printed value.
string	$indent	String to indent with.
int	$first_line	Index of first line to indent.

Return

string
