Formatting

This class contains functions to help (re)format data.

Use:
\blobfolio\common\format (by value)
\blobfolio\common\ref\format (by reference)

array_flatten()

Push all values in a multi-dimensional array into a sequential, single-dimensional array.

Versions

• By Value
• By Reference

Arguments

Type	Description
array	Array.

Returns

If passing by value a new array is returned, otherwise TRUE.

Example

$arr = array(1, array(2, array(3)));
\blobfolio\common\ref\format::array_flatten($arr); // [1, 2, 3]

array_to_indexed()

Rebuild a key=>value array so that each value is an array containing the original key and value. This can be helpful if exporting associative array data to Javascript, for example.

Versions

• By Value
• By Reference

Arguments

Type	Description
array	Array.

Returns

If passing by value a new array is returned, otherwise TRUE.

\blobfolio\common\format::array_to_indexed($arr);
/*
array(
    0 => array(
        [key] => fruit,
        [value] => apple
    ),
    1 => array(
        [key] => vegetable,

    )
)
*/

cidr_to_range()

Convert a CIDR to a minimum/maximum range of IPs.

ip_to_number()

Convert an IPv4 or IPv6 address to its numerical equivalent. This requires the PHP extensions bcmath or gmp.

Versions

• By Value
• By Reference

Arguments

Type	Description
string	IP address.

Returns

If passed by value, returns the numerical IP address or FALSE, otherwise TRUE/FALSE.

Example

// By value.

// By reference.
\blobfolio\common\ref\format::ip_to_number($foo);

Versions

• By Value
• By Reference

Arguments

Type	Description
string	IP address.

Returns

If passed by value, returns the subnet or FALSE, otherwise TRUE/FALSE.

Example

// By value.
$foo = \blobfolio\common\format::ip_to_subnet('50.116.18.174'); // 50.116.18.0/24

// By reference.
\blobfolio\common\ref\format::ip_to_subnet($foo);

json()

Convert a JSON or JSON-like string into proper JSON. This will fix key/value quoting, remove comments, remove trailing commas, correct UTF-8 issues, etc.

Versions

• By Value
• By Reference

Arguments

Type	Description	Notes	Default
mixed	Data.	If a JSON(ish) string is passed, its formatting will be sanitized/corrected; if something else is passed, it will be converted to JSON.
bool	Pretty print.	If TRUE, output will be pretty-printed.	TRUE

Returns

If passed by value, returns JSON string or NULL, otherwise TRUE/FALSE.

json_decode()

A json_decode() wrapper that applies the same formatting forgiveness as the above ::json() function, giving the data a fighting chance of coming through.

Note: This always returns objecty data as an associative array.

Versions

• By Value
• By Reference

Arguments

Type	Description
string	JSON.

Returns

If passed by value, returns the decoded data, otherwise TRUE/FALSE.

links()

Convert plain-text URLs, domains, email addresses, and telephone numbers into clickable (HTML) links.

Malformed data will be left alone, as will any non-FQDN domain or email address.

Unicode hosts are supported if the PHP extension intl is installed, but the resulting href attribute will be converted to Punycode/ASCII.

People are very inconsistent at how they write telephone numbers. This looks specifically for international formatting (+1 201-555-0123), or common North American 10-digit representations like (201) 555-0123, 201-555-0123, 201.555.0123, etc. Other types of numbery bits, or phone-ish strings that don't validate, will be ignored.

Versions

• By Value
• By Reference

Arguments

Type	Description	Notes
string	String.
array	Attributes.	Attributes to add to generated links. See below.

All attributes are optional.

Type	Key	Description
string, array	class	Class(es).
string	rel	Relation.
string	target	Target.

Returns

If passed by value, returns the text with added links, otherwise TRUE.

Example

// By value.
$foo = \blobfolio\common\format::links('Welcome to domain.com!'); // Welcome to <a href="http://domain.com">domain.com</a>!

$args = array(
  'target'=>'_blank'
);
$foo = \blobfolio\common\format::links('me@domain.com', $args); // <a href="mailto:me@domain.com" target="_blank">me@domain.com</a>

// By reference.
\blobfolio\common\ref\format::links($foo);

list_to_array()

Convert a delimited list, or array of delimited lists, into a normal, single-dimensional array.

This is useful, e.g., in parsing function arguments that might be passed as proper arrays or comma-delimited strings.

Note: empty values are always ignored, but other types of falsey values are fine.

Versions

• By Value
• By Reference

Arguments

Type	Description	Notes
mixed	List.
array	Options.	See below for details.

Returns

If passed by value, returns an array of values, otherwise TRUE.

Example

// Possible arguments, defaults shown.
$args = array(
  'delimiter'=>',', // List delimiter.
  'cast'=>'string', // Cast output values as this type.
  
  'trim'=>true,     // Trim values, so e.g. "1, 2" and "1,2" wind up the same.
  'min'=>null,      // Remove values less than this.
  'max'=>null,      // Remove values greater than this.

  'unique'=>true,   // Remove duplicate values.
  'sort'=>false,    // Sort values.
);

// By value.
$foo = \blobfolio\common\format::list_to_array('1,,2,3', $args); // [1, 2, 3]

$args = array(
  'min'=>'2'
);
$foo = \blobfolio\common\format::list_to_array('1,2,3', $args); // [2,3]

bool	Remove trailing .00.	If TRUE, cents will be stripped off whole-dollar amounts.	FALSE

Returns

If passing by value, returns the formatted amount, otherwise TRUE.

// By value.
$foo = \blobfolio\common\format::money(.75, true); // 75¢
$foo = \blobfolio\common\format::money(.75, false); // $0.75

// By reference.
