Methods
Removes all invalid UTF-8 characters from a string.
Returns a specific character in UTF-8 from code point (number in range 0x0000..D7FF or 0xE000..10FFFF).
Returns a code point of specific character in UTF-8 (number in range 0x0000..D7FF or 0xE000..10FFFF).
Returns a part of UTF-8 string specified by starting position and length. If start is negative, the returned string will start at the start'th character from the end of string.
Removes control characters, normalizes line breaks to \n, removes leading and trailing blank lines,
trims end spaces on lines, normalizes UTF-8 to the normal form of NFC.
Converts line endings to \n used on Unix-like systems.
Converts line endings to platform-specific, i.e. \r\n on Windows and \n elsewhere.
Converts UTF-8 string to ASCII, ie removes diacritics etc.
Modifies the UTF-8 string to the form used in the URL, ie removes diacritics and replaces all characters except letters of the English alphabet and numbers with a hyphens.
Truncates a UTF-8 string to given maximal length, while trying not to split whole words. Only if the string is truncated, an ellipsis (or something else set with third argument) is appended to the string.
Indents a multiline text from the left. Second argument sets how many indentation chars should be used, while the indent itself is the third argument (tab by default).
Converts all characters of UTF-8 string to lower case.
Converts the first character of a UTF-8 string to lower case and leaves the other characters unchanged.
Converts all characters of a UTF-8 string to upper case.
Converts the first character of a UTF-8 string to upper case and leaves the other characters unchanged.
Converts the first character of every word of a UTF-8 string to upper case and the others to lower case.
Compares two UTF-8 strings or their parts, without taking character case into account. If length is null, whole strings are compared, if it is negative, the corresponding number of characters from the end of the strings is compared, otherwise the appropriate number of characters from the beginning is compared.
Finds the common prefix of strings or returns empty string if the prefix was not found.
Returns number of characters (not bytes) in UTF-8 string.
Removes all left and right side spaces (or the characters passed as second argument) from a UTF-8 encoded string.
Pads a UTF-8 string to given length by prepending the $pad string to the beginning.
Pads UTF-8 string to given length by appending the $pad string to the end.
Reverses UTF-8 string.
Returns part of $haystack before $nth occurence of $needle or returns null if the needle was not found.
Returns part of $haystack after $nth occurence of $needle or returns null if the needle was not found.
Returns position in characters of $nth occurence of $needle in $haystack or null if the $needle was not found.
Divides the string into arrays according to the regular expression. Expressions in parentheses will be captured and returned as well.
Searches the string for the part matching the regular expression and returns
an array with the found expression and individual subexpressions, or null.
Searches the string for all occurrences matching the regular expression and returns an array of arrays containing the found expression and each subexpression.
Replaces all occurrences matching regular expression $pattern which can be string or array in the form pattern => replacement.
