11/20/2023 0 Comments Php trim full name![]() ![]() We have also seen how to specify our own whitespace character for trimming. In this article, we have gone through in-depth the usage of trim(), ltrim(), and rtrim() functions which are basically used to remove the characters which are not required from a string. Similarly, when rtrim is used by specifying to trim numbers from 0 to 9, it only trims the numbers from the end of the string. Example #6 – To trim using rtrim() and ltrim()Īs seen in the above example when ltrim is used, it only trims the extra spaces at the starting of the string. Hence in the above example using the above method it will trim the numbers “123” and “456” from the beginning and the end of the input string respectively. It also allows us the use of dot notation using which if we specify as “0.9” the function removes all numbers in the input string ranging from 0 to 9. As we can see in the output, the mentioned characters are trimmed.Įxample #5 – To display trimming of numbers as well.īy using the trim() function we can also trim the numbers by specifying it in the second parameter list. Hence, we will use the optional second parameter in the trim function to explicitly specify a range of characters (“\n” and “\r” in this case) that needs to be trimmed. In the above example, we can see that the input string has 2 special characters “\n” and “\r”. Example #4 – To remove more than one special character. Like the spaces in between “Example” and “to” are still the same. Also please note that only the whitespaces between the start and end of the string are trimmed and not the ones in between the sentence. As seen in the output, all the blank spaces from the beginning have been trimmed out and the proper input string is displayed. Hence to remove this we are using the trim function. In the above example, we can see that the input string has a lot of blank spaces at its beginning. Example #3 – To remove blank space characters. When we try the same code by removing the trim function we can see that an extra tab will get printed at the end of the string as we have appended it in a $str_new parameter. Simultaneously trim function is used which removes this tab character from the end of the string. ![]() First, we are assigning the required string to a parameter called str1, and then using another parameter $str_new to append a tab at the end of the $str1. In the above example, we are using the trim function to remove tab (“\t”) character by explicitly specifying the character in the second parameter of the trim function as seen. After using the trim function as seen in the output it trims all the \n present in the input string and displays the string. Here $str is the variable to which the required string or a sentence is to be declared. The above example displays a basic program for the usability of trim() function. The same thing can be seen in the output. In the string assigned we are displaying newlines as part of the sentence for testing purposes. In the above example, we are showcasing to see the output without the use of the trim() function. Given below are the examples of trim() in PHP: Example #1 – To remove the newline character. rtrim(): This is used to trim characters from the end of the input string.ltrim(): This is used to trim characters from the beginning of the input string.trim(): This is a normal one and can be used to trim from both the beginning and end of a string.There are 3 different types of trim() functions that can be used for the below-mentioned purposes: Return values: Outputs a trimmed string.With this, we can also specify a wide range of characters. All the characters mentioned inside the braces will be trimmed. character_mask: This is an optional field that can also be specified using this parameter.str: This is the input string that will be trimmed of whitespaces.“\x0B” (ASCII 11 (0x0B)) which represents a vertical tab.“\0” (ASCII 0 (0x00)) which is called the NULL byte.“\r” (ASCII 13 (0x0D)) which is a carriage return character.“\n” (ASCII 10 (0x0A)) which represents a new line character.“\t” (ASCII 9 (0x09)) which is a tab character.” ” (ASCII 32 (0x20)) which is a normal space character.Hence without the second parameter, the trim function trims the below parameters by default: The second parameter in the syntax is optional and is used to define explicitly what characters should be trimmed exactly. Trim ( string $str ) : stringĪs shown above, input parameters for this trim function include the input string which will be trimmed of its whitespaces from the beginning and the end of its string $str. ![]()
