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 ...

The mb_strripos() function in PHP is used to search the last existing of a string in another string. This function is not case-sensitive. It performs multi-byte safe strripos() operation based on the number of characters. It returns the specified needle position count from the starting of the haystack string.Syntaxinteger mb_strripos( $str_haystack, $str_needle, $integer_offset=0, $str_encoding )Parametersmb_strripos() accepts the following four parameters −str_haystack − It is the string used to get the position of the last occurrence of the string needle.str_needle − This is used to find the string from ...

Suppose we are given an array 'arr' that contains n number of sorted integer values. We are also given an array 'query' of size q, and we have to tell either the values in ‘query’ are present in the given array 'arr' or not. If a value in query is present in arr, we print "Present" along with the position where the value is situated in. Otherwise, we print "Not present" and print the position in arr, where the minimum value greater than the value in query is located. We have to remember that the arrays are 1-indexed.So, if the ...

Suppose we are given three double values. We have to format them and print them in the following format.We have to print the integer part of the first value in hexadecimal format with lowercase letters.We have to print the second value up to two decimal places, putting a sign before it to show whether it is positive or negative. The second value to be printed has to be rightjustified and 15 characters long, padded with underscores in the left unused positions.We have to print the third value up to nine decimal places in a scientific notation.So, if the input is ...

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 − ...

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 − ...

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 ...

The mb_stristr() function in PHP is used to search the first existence of a string in another given string; this function is not case-sensitive. mb_stristr() searches for the first existence of the needle in a given haystack string and returns the portion of the haystack. It will return False if the needle is not found.Syntaxstring mb_stristr( $str_haystack, $str_needle, $bool_before_needle=false, $str_encoding=empty )Parametersmb_stristr() accepts the following four parameters −$str_haystack − This parameter is used to get the first existence of the string needle.$str_needle − This parameter is used to find ...

The mb_stripos() function in PHP is used to find the position of first occurrence of a string within another string. It is "case-insensitive". mbstripos() returns the numeric position of the first existence of the needle in a given haystack string. If the needle is not found, it will return False.Syntaxinteger mb_stripos($str_haystack, $str_needle, $int_offset=0, $str_ecoding=empty)ParametersIt accepts the following four parameters −$str_haystack − This parameter is used to get the position of the first existence of the needle from the given string.$str_needle − This parameter is used to find the string from the given haystack.$int_offset − This parameter is used to search ...
