void array_chunk( mixed $input, mixed $size, [mixed $preserve_keys = false])

Provides array_chunk() for PHP 4.1 users.

Tags:

array array_chunk_fill( array $list, integer $chunk, [boolean $assoc = false], [mixed $fill = ' '])

Calls array_chunk(), but adds a parameter $fill, which "fills out" the potentially uneven number if items in the last array with the value of $fill.

Tags:

array	$list
integer	$chunk
boolean	$assoc
mixed	$fill

mixed array_search( [mixed $needle = ''], [array $haystack = ''])

If the PHP version is less than 4.0.5, emulates the array_search() function.

Tags:

Parameters

mixed	$needle
array	$haystack

array assocify( array $arr)

Turns a regular array into an associative array with a $value => $value new key/value relation. For example, an array [1=>Joe,2=>Jane,3=>Joe] would become [Joe=>Joe,Jane=>Jane]. Please note the loss of duplicate values.

Tags:

Parameters

array

$arr

string better_crypt( string $pass, [string $salt = ''])

Makes sure that the salt is always two characters in length before sending it to the crypt() function. Also generates its own two character salt if none is provided.

Tags:

Parameters

string	$pass
string	$salt

boolean better_crypt_compare( string $pass, string $original)

Calls the better_crypt() function instead of crypt() when comparing a new password to the original to see if it matches up.

Tags:

Parameters

string	$pass
string	$original

int better_strrpos( string $haystack, string $needle)

strrpos() which allows multiple characters in the needle.

string htmlentities_compat( string $val1, [string $val2 = ENT_COMPAT], [string $val3 = 'iso-8859-1'])

Where htmlentities() causes corruption of data in alternate character

sets, this function aims to translate the necessary entities without damaging the data. Currently does a str_replace for the following entities:

• '&' * => '&'
• '<' * => '<'
• '>' * => '>'
• '<' * * => '&lt;'
• '>' * * => '&gt;'
• '"' * * => '"'

It also does an extra preg_replace for & followed by a space/tab/cr/lf and replaces the & with a &amp;.

Tags:

Parameters

string	$val1
string	$val2
string	$val3

string htmlentities_reverse( string $val1)

Reverses the htmlentities_compat() function exactly.

Tags:

Parameters

string

$val1

string html_marker( string $note)

Creates an HTML comment padded with dashes for easily marking sections of a document. Hnady for viewing the source of large documents.

Tags:

Parameters

string

$note

void info( mixed $value, [boolean $full = false])

Wraps a print_r() or var_dump() of the given $value with a set of

tags around it, and echoes it.

Tags:

Parameters

mixed	$value
boolean	$full

boolean is_a( string $class, string $match)

If the PHP version is less than 4.2.0, emulates the is_a() function, which determines whether the object, $class, is of the class specified by $match.

Tags:

Parameters

string	$class
string	$match

boolean is_assoc( mixed $arr)

Determines whether the specified variable is an associative array.

Tags:

Parameters

mixed

$arr

string localdate( string $format, [int $unixdate = ''])

Parameters

string	$format
int	$unixdate

array make_assoc( array $array, [string $key = ''], [string $value = ''])

Creates a single-level associative array out of an array of objects or an array of associative arrays. $key and $value specify the property or array key name to use for their respective values in the new associative array.

Tags:

Parameters

array	$array
string	$key
string	$value

object &make_obj( array $array)

Note: Deprecated in favour of a simple:

$obj = (object) $array;

Creates an object out of a hash (or any other type). There is no make_hash() function because that can simply be cast as well ($array = (array) $obj). Thanks to Demian Turner for pointing out this equivalence.

Tags:

Parameters

array

$array

string mime( string $file)

Determines the content type of a file based on a small list of common types.

Useful when mime_content_type() isn't available or isn't configured correctly.

Tags:

Parameters

string

$file

void mime_content_type( mixed $file)

int readfile_chunked( string $filename, [boolean $retbytes = true])

Replacement for readfile() in PHP5 which doesn't encounter memory limits.

Tags:

array sql_split( string $sql)

Splits an SQL script into distinct queries which can be evaluated or manipulated individually.

string vsprintf( string $str, array $args)

If the PHP version is less than 4.1.0, emulates the vsprintf() function using a call_user_func_array() with the sprintf() function. The use of this function in the saf.I18n package was causing fatal errors in Sitellite on earlier PHP versions.

Tags:

Parameters

string	$str
array	$args
