Method Details

base64UrlDecode() public static method (available since version 2.0.12)

Decodes "Base 64 Encoding with URL and Filename Safe Alphabet" (RFC 4648)

public static string base64UrlDecode ( $input )
$input	string	Encoded string.
return	string	Decoded string.

base64UrlEncode() public static method (available since version 2.0.12)

Encodes string into "Base 64 Encoding with URL and Filename Safe Alphabet" (RFC 4648)

Note: Base 64 padding = may be at the end of the returned string. = is not transparent to URL encoding.

public static string base64UrlEncode ( $input )
$input	string	The string to encode.
return	string	Encoded string.

basename() public static method

Returns the trailing name component of a path.

This method is similar to the php function basename() except that it will treat both \ and / as directory separators, independent of the operating system. This method was mainly created to work on php namespaces. When working with real file paths, php's basename() should work fine for you. Note: this method is not aware of the actual filesystem, or path components such as "..".

public static string basename ( $path, $suffix = '' )
$path	string	A path string.
$suffix	string	If the name component ends in suffix this will also be cut off.
return	string	The trailing name component of the given path.

byteLength() public static method

Returns the number of bytes in the given string.

This method ensures the string is treated as a byte array by using mb_strlen().

public static integer byteLength ( $string )
$string	string	The string being measured for length
return	integer	The number of bytes in the given string.

byteSubstr() public static method

Returns the portion of string specified by the start and length parameters.

This method ensures the string is treated as a byte array by using mb_substr().

public static string byteSubstr ( $string, $start, $length = null )
$string	string	The input string. Must be one character or longer.
$start	integer	The starting position
$length	integer	The desired portion length. If not specified or `null`, there will be no limit on length i.e. the output will be until the end of the string.
return	string	The extracted part of string, or FALSE on failure or an empty string.

countWords() public static method (available since version 2.0.8)

Counts words in a string

public static integer countWords ( $string )
$string	string

dirname() public static method

Returns parent directory's path.

This method is similar to dirname() except that it will treat both \ and / as directory separators, independent of the operating system.

public static string dirname ( $path )
$path	string	A path string.
return	string	The parent directory's path.

endsWith() public static method

Check if given string ends with specified substring.

Binary and multibyte safe.

public static boolean endsWith ( $string, $with, $caseSensitive = true )
$string	string	Input string to check
$with	string	Part to search inside of the $string.
$caseSensitive	boolean	Case sensitive search. Default is true. When case sensitive is enabled, $with must exactly match the ending of the string in order to get a true value.
return	boolean	Returns true if first input ends with second input, false otherwise

explode() public static method (available since version 2.0.4)

Explodes string into array, optionally trims values and skips empty ones

public static array explode ( $string, $delimiter = ',', $trim = true, $skipEmpty = false )
$string	string	String to be exploded.
$delimiter	string	Delimiter. Default is ','.
$trim	mixed	Whether to trim each element. Can be: boolean - to trim normally; string - custom characters to trim. Will be passed as a second argument to `trim()` function. callable - will be called for each value instead of trim. Takes the only argument - value.
$skipEmpty	boolean	Whether to skip empty strings between delimiters. Default is false.

normalizeNumber() public static method (available since version 2.0.11)

Returns string represenation of number value with replaced commas to dots, if decimal point of current locale is comma

public static string normalizeNumber ( $value )
$value	integer\|float\|string

startsWith() public static method

Check if given string starts with specified substring.

Binary and multibyte safe.

public static boolean startsWith ( $string, $with, $caseSensitive = true )
$string	string	Input string
$with	string	Part to search inside the $string
$caseSensitive	boolean	Case sensitive search. Default is true. When case sensitive is enabled, $with must exactly match the starting of the string in order to get a true value.
return	boolean	Returns true if first input starts with second input, false otherwise

truncate() public static method

Truncates a string to the number of characters specified.

public static string truncate ( $string, $length, $suffix = '...', $encoding = null, $asHtml = false )
$string	string	The string to truncate.
$length	integer	How many characters from original string to include into truncated string.
$suffix	string	String to append to the end of truncated string.
$encoding	string	The charset to use, defaults to charset currently used by application.
$asHtml	boolean	Whether to treat the string being truncated as HTML and preserve proper HTML tags. This parameter is available since version 2.0.1.
return	string	The truncated string.

truncateHtml() protected static method (available since version 2.0.1)

Truncate a string while preserving the HTML.

protected static string truncateHtml ( $string, $count, $suffix, $encoding = false )
$string	string	The string to truncate
$count	integer
$suffix	string	String to append to the end of the truncated string.
$encoding	string\|boolean

truncateWords() public static method

Truncates a string to the number of words specified.

public static string truncateWords ( $string, $count, $suffix = '...', $asHtml = false )
$string	string	The string to truncate.
$count	integer	How many words from original string to include into truncated string.
$suffix	string	String to append to the end of truncated string.
$asHtml	boolean	Whether to treat the string being truncated as HTML and preserve proper HTML tags. This parameter is available since version 2.0.1.
return	string	The truncated string.
