PHP – mb_ereg_search_init() function
The mb_ereg_search_init() function in PHP is used to setup string and regular expression pattern for a multibyte regular expression match. The values are used for mb_ereg_search_regs, mb_ereg_search_pos, and mb_ereg_search.Syntaxbool mb_ereg_search_init( $str_string, $str_pattern=null, $str_options=null )Parametersmb_ereg_search_init() accepts three parameters −string − This is the search string.pattern − This is the search pattern.options − This is the search option. .Return Valuesmb_ereg_search_init() returns True on success and False on failure.ExampleOutputbool(true) bool(true)

The mb_strcut() function in PHP is used to get a part of a specified string. It extracts the substring from a given string. It operates on bytes instead of characters. If the cut position happens to be between two bytes of multi-byte characters, then the cut is achieved starting from the first byte of those characters.Syntaxstring mb_strcut( $str_string, $int_start, $int_length=null, $str_encoding=null );For example:mb_strcut( string="Onlinetutorial", int= 6, length=5, encoding= "UTF-8" );Parametersmb_strcut() accepts the following four parameters −str_string ...
Read MorePHP – mb_strrichr() function
The mb_strrichr() function in PHP is used to find the last occurrence of a character in a string within another string. This function is not case-sensitive like mb_strrchr(). This function finds the last occurrence of a needle in the given haystack string and returns that portion of the haystack. It returns false if a needle is not found in the haystack string.Syntaxstring mb_strrichr( $str_haystack, $str_needle, $bool_before_needle=false, $str_encoding )Parametersmb_strrichr() accepts the following four parameters −str_haystack − The string from which to get the last occurrence of the needle.str_needle − ...
Read MorePHP – mb_eregi() function
The mb_eregi (multibyte regular expression ignore) function in PHP is used to ignore the regular expression match with multibyte support. This function performs the case-insensitive regular expression match with the multibyte support.Syntaxbool mb_eregi( $str_ pattern, $str_string, $arr_matches=null )For example(pattern = "or", string = "Hello World"); Parametersmb_eregi() accepts the following three parameters −pattern − This parameter matches the pattern in the given string.mb_ereg ("or", "Hello World") // "or" is the pattern that will be matched // in the given string "Hello World".string − This parameter is used to search the string.matches − ...
Read MorePHP – mb_strrpos() function
The mb_strrpos() function in PHP is used to find the position of the last occurrence of a string in another string. This function performs the multibyte safe strrpos() operation based on the number of characters. It counts the needle position from the starting of the haystack string.Syntaxint mb_strrpos( $str_haystack, $str_needle, $int_offset=0, $str_encoding=empty )Parametersmb_strrpos() accepts the following four parameters −$str_haystack − This parameter is used to check the string for the last existence of the needle string.$str_needle − This needle parameter is used to find the string in the ...
Read MorePHP – mb_strimwidth (multybyte strimwidth) function
The mb_strimwidth() function in PHP is used to truncate a given string with specified width. It is used to cut out the specified width from a given string.Syntaxstring mb_strimwidth($str_string, $int_start, $int_width, $str_trim_marker, $str_encoding)For example, mb_strimwidth($str_string: "PHP Tutorials", $int_start: 2, $int_width: 10, $str_trim_marker: "...", ); Parametersmb_strimwidth() accepts five different parameters to trim the string width.$str_string − The string that is to be decoded.$int_start − This integer parameter will trim the string from the specified start position. It will trim the string of characters from the beginning of the string.$int_width − The width of the desired trim. Negative widths count from the ...

The mb_preferred_mime_name() function in PHP is used to return the MIME string for the character encoding and it returns the charset string. It gets a MIME (Multipurpose Internet Mail Extensions) charset string for the specific encoding.Syntaxstring mb_preferred_mime_name($string_encoding)Parametersmb_preferred_mime_name() accepts only one parameter −$string_encoding − This parameter is used to check the encoding.Return ValuesThe mb_preferred_mime_name() function returns the MIME charset string for the charset encoding. It returns False if no charset is preferred for the given encoding.ExampleLet us now take an example and see how it works −OutputIt will produce the following output −EUC-JP
Read MorePHP – Parse the GET, POST, and COOKIE data using mb_parse_str()
The mb_parse_str() function in PHP is used to parse the GET, POST, and COOKIE data and it sets the global variable. It parses the URL encoded data and detects the encoding. After that, it converts the coding in the internal encoding and sets values for the global variables. This function is supported in PHP 7 or higher versions.Syntaxstring mb_parse_str($str_string, $array_result)Parametersmb_parse_str() accepts the following two parameters −$str_string − This parameter is used for the URL encoded data.$result − The result parameter will be an array holding the decrypted and character encrypted converted values.Return ValuesThe mb_parse_str() function returns True on success or ...

The mb_list_encodings() function in PHP is used to return an array of all supported encodings. This function is supported in PHP 5 or higher version.Syntaxarray mb_list_encodings()Parametersmb_list_encodings() takes no parameters.Return ValuesThis function returns a numerically indexed array.Errors/Exceptionsmb_list_encodings() does not produce any errors.Examplemb_list_encodings() does not produce any errors.OutputIt will produce the following output −array(87) { [0]=> string(4) "pass" [1]=> string(4) "auto" [2]=> string(5) "wchar" [3]=> string(7) "byte2be" [4]=> string(7) "byte2le" [5]=> string(7) "byte4be" [6]=> string(7) "byte4le" [7]=> string(6) "BASE64" [8]=> string(8) "UUENCODE" [9]=> string(13) ...

The mb_http_output() function in PHP is used to get or set the HTTP output character encoding. An output, after this function is called, will be converted from the set internal encoding to the specified encoding.Syntaxstring|bool mb_http_output(str $encoding = null)Parametersmb_http_output() accepts only a single parameter −$encoding − It is used to set the HTTP output character encoding to the encoding. If the encoding is omitted, then mb_http_output() will return the current HTTP output character encoding.Return ValuesIf the encoding is omitted, then the mb_http_output() function will return the current HTTP output character encoding.
