$string_length: Length of chracters you want to showĤ. $string_start: get or start from the position of stringģ. $string: The string where the character is to extract.Ģ. But if you have special character in your string then itll show a. Mb_substr($string, $string_start, $string_length, $string_encode)ġ. To get the first character of string in PHP, you can use a built in function i.e. There are four parameters used in this funtion. i want to get the first character of the string j. i want to get the first character of that string. i am passing the variable value to the substr to get the first character of the string. here i have a name in the session variable. Now to get first character can use another function string function which is also a built-in function i.e. I need to get the first character of the given string. So this function is not always useful in this type of cases. But if you have special character in your string then it'll show a black question mark or other symbol rather than to show that special character as an output. But, if the character set isn't known/can't be detected and you have no choice but to deal with dirty data, this is probably the simplest solution.To get the first character of string in PHP, you can use a built in function i.e. ![]() ![]() I will give you very simple examples to get the first character from a string. So it's still best to convert the encoding of the parameters to be the same first. We will use the substr() PHP function to get the first character from the string. For instance, ド in Windows-1252 will match ド from the above string. var_export ( mb_str_contains ( $string, $contains2 ), true ). INSTR(), Return the index of the first occurrence of substring. ![]() addslashes () Returns a string with backslashes in front of predefined characters. addcslashes () Returns a string with backslashes in front of the specified characters. No installation is required to use these functions. var_export ( str_contains ( $string, $contains2 ), true ). Insert substring at specified position up to specified number of characters. The PHP string functions are part of the PHP core. var_export ( mb_str_contains ( $string, $contains ), true ). var_export ( str_contains ( $string, $contains ), true ). We can compare str_contains to the above suggested function: I used mb_substr_count() instead of mb_strpos() because mb_strpos() will still match partial characters as it's doing a binary search. ![]() Here's a "mb_*"-esque function that searches the string: If the substring is not found it returns false. This won't be a concern for most people, but if you are mixing old and new data, especially if reading data from a file, it could be an issue. The strpos() function returns the position of the first occurrence of a substring in a string. This function doesn't always produce the expected results if you have a needle that isn't UTF-8 but are looking for it in a UTF-8 string.
