Meta characters

When you define a sequence of characters in the charlist argument make sure that you know what characters come between the characters that you set as the start and end of the range.

You can also specify the characters you want to strip, by means of the charlist parameter. Simply list all characters that you want to be stripped. With.. you can specify a range of characters.

With an empty prefix, the returned string will be 13 characters long. If lcg is TRUE, it will be 23 characters.

The special regular expression characters are

There are many languages in which all characters can be expressed by single byte. Multi byte character codes are used to express many characters for many languages. mbstring is developed to handle Japanese characters. However, many mbstring functions are able to handle character encoding other than Japanese.

瞰赽 2. Splitting a string into component characters.

Returns string with all alphabetic characters converted to lowercase.

Returns string with all alphabetic characters converted to uppercase.

Returns a string in which all non alphanumeric characters except

Returns the number of characters that did not fit in the specified box. Returns 0 if all characters fit or the width and height parameters were set to 0 for single line formattting.

Characters before and after the formatting string will be returned unchanged.

To ensure alignment, any characters appearing before or after the number in the formatted output such as currency or sign symbols are padded as necessary with space characters to make their positive and negative formats an equal length.

Returns the length of the initial segment of str1 which consists entirely of characters in str2.

If from and to are different lengths, the extra characters in the longer of the two are ignored.

Returns the length of the initial segment of str1 which does not contain any of the characters in str2.

The options parameter may contain the following elements individual characters, and characters followed by a colon to indicate an option argument is to follow. For example, an option string x recognizes an option x, and an option string x recognizes an option and argument x argument. It does not matter if an argument has leading white space.

Returns TRUE if every character in text has a special control function, FALSE otherwise. Control characters are e.g. line feed, tab, esc.

蛁 Make sure you do not have any newline characters in the to or subject, or the mail may not be sent properly.

Each pair of escape sequences partitions the complete set of characters into two disjoint sets. Any given character matches one, and only one, of each pair.

Tightness allows you to control the amount of white space between characters. This amount is added to the normal character width and can also be negative.

Returns TRUE if every character in text creates some sort of white space, FALSE otherwise. Besides the blank character this also includes tab, vertical tab, line feed, carriage return and form feed characters.

This function returns the given string converted from one Cyrillic character set to another. The from and to arguments are single characters that represent the source and target Cyrillic character sets. The supported types are

The power of regular expressions comes from the ability to include alternatives and repetitions in the pat tern. These are encoded in the pattern by the use of meta characters, which do not stand for themselves but instead are interpreted in some special way.

Soundex keys have the property that words pronounced similarly produce the same soundex key, and can thus be used to simplify searches in databases where you know the pronunciation but not the spelling. This soundex function returns a string 4 characters long, starting with a letter.

The fourth use of backslash is for certain simple asser tions. An assertion specifies a condition that has to be met at a particular point in a match, without consuming any characters from the subject string. The use of subpatterns for more complicated assertions is described below. The backslashed assertions are

This function performs the ROT13 encoding on the str argument and returns the resulting string. The ROT13 encoding simply shifts every letter by 13 places in the alphabet while leaving non alpha characters untouched. Encoding and decoding are done by the same function, passing an encoded string as argument will return the original version.

When Jarrett J. Krosoczka was a kid, he didn t play sports, but he loved art. He paints the funny and touching story of a little boy who pursued a simple passion to draw and write stories. With the help of a supporting cast of family and teachers, our protagonist grew up to become the successful creator of beloved children s book characters, and a vocal advocate for arts education.

This module contains an interface to the GNU Recode library, version 3.5. The GNU Recode library converts files between various coded character sets and surface encodings. When this cannot be achieved exactly, it may get rid of the offending characters or fall back on approximations. The library recognises or produces nearly 150 different character sets and is able to convert files between almost any pair. Most RFC 1345 character sets are supported.

Note that only the first call to strtok uses the string argument. Every subsequent call to strtok only needs the token to use, as it keeps track of where it is in the current string. To start over, or to tokenize a new string you simply call strtok with the string argument again to initialize it. Note that you may put multiple tokens in the token parameter. The string will be tokenized when any one of the characters in the argument are found.
