Negative Length and Positive Starting PositionĪdvance your career as a MEAN stack developer with the Full Stack Web Developer - MEAN Stack Master's Program. Positive Length and Negative Starting PositionĦ. Here are some examples to explain the use of these parameters: 1. If the parameter is not passed, then the function returns a string starting from starting_position till the end.If the length parameter is zero, null or False will be returned.Many characters are omitted from the end if the length passed is negative. If the length is negative, then the substring begins from the starting_position and extracts the length from the string's end.If the length is positive, then the substring includes the number of characters passed in this parameter beginning from the starting_position.length_of_substring: This is an optional parameter, and it is an integer value referring to the length of the string cut from the original one. If the starting_position is greater than the string size, then the function returns FALSE.ģ.The counting begins from 1 at the end of the string. If the integer is negative, the returned string starts from that position from the end of the string.If the integer is positive, the returned string starts from that position in the string.
The input is an integer, and it is a required parameter. starting_position: This parameter includes the position, which is the index from where the part of the string needs to be extracted. The input string must at least be one character.Ģ. string: This parameter includes the original string, i.e., the string which needs to be modified or cut. One parameter is optional, and the other two are mandatory.ġ. The substr in PHP function has three arguments or parameters. We want the function to return “in php” from the string.

Substr(string, starting_position, length_of_substring) The substr in php has the following syntax: Let us see how we can use substr() to cut a portion of the string. The function returns the substring specified by the start and length parameter. Substr in PHP is a built-in function used to extract a part of the given string.
