Php substring string10/31/2023 ![]() We can also specify the length of the substring, and this parameter is optional. strstr() function is also a PHP function to see if the substring, character, or word can exist within another string. This function allows us to extract the string from the given string by specifying the position at which the function begins to extract the substring. To extract the substring from the input string, PHP offers an in-built feature substr() function. In this lesson, we have discussed how to extract substrings from the string in PHP. In the given example, we have specified the negative value for the length parameter within the substr() function. We can also specify the negative value for the length parameter. Tonight Example: Using substr() function with negative length The function returns the string which is at the seventh index from the end of the string. In the given example, we have specified the negative index for the extracted string. Studytonight Example: Using substr() function with negative value So the output string will start from the index 11 and end at the end of the string. In the even example, we have used the substr() function but do not specify the length of the extracted string. To Example: Using substr() function will default length argument It replaces all occurrences of the search. ![]() ![]() The substring starts with the index 8 and the length of the string is 2. If you need to find and remove all occurrences of a substring in a string, you can use the strreplace() function. In the given example, we have used the substr() function to extract the substring from the input string. $length specifies the length of the extracted string. ![]() It specifies the position at which the function begins to extract the substring. $start specifies where to start the string the needs to be extracted. In the first parameter, we have to specify the input string and the second parameter specifies the position at which the function begins to extract the substring from the input string, and the third-string specifies the length of the characters that are to be extracted from the input string. Out of three parameters, the first two parameters are necessary to specify while the third one is optional. This function takes three parameters that are string, start length, and the length of the extracted string. This function is used to extract the substring from any given string. $haystack = 'My website name is BrainBell.The substr() function is a pre-defined PHP function. This function works similar to the str_starts_with and the str_contains functions, except that it searches for the substring $needle at the end of the string $haystack. Str_ends_with(string $haystack, string $needle): bool If you are writing a script that contains the str_contains() function and you want to ensure that your code must run on versions prior to PHP 8 then create your own str_contains() function:
