![]() ![]() ![]() ![]() The offset parameter determines the start of the returned substring and the length parameter determines the length of the substring. 'r' (ASCII 13 (0x0D)), a carriage return. 'n' (ASCII 10 (0x0A)), a new line (line feed). Without the second parameter, rtrim () will strip these characters: ' ' (ASCII 32 (0x20)), an ordinary space. Let me know what you think in the comments. The first parameter is the string you want to trim. This function returns a string with whitespace (or other characters) stripped from the end of string. This is how we shorten the length of a string and replace it with three (3) dots in PHP. If itâs not, we just return the given string. Technical Details More Examples Example Remove whitespaces from both sides of a string: Ä®cho trimString("Hello Codeflare", ".", 3) function trimString($string, $repl, $limit) So we will write a function that is re-usable and which we can always call or use in any other programming. Then it checks if the length of the string is greater than the maximum number of. It first trims the string to remove any leading or trailing whitespace. This is usually needed in a software application, especially when the string length is too long to show to the user. To truncate a string in PHP to the word closest to a certain number of characters, you can use the following code: This function takes a string and a maximum number of characters as arguments. It's useful for cleaning up comments, articles, or mail that users post to your site, making it so there's no extra blank space or blank lines.Using PHP, we can shorten the length of our string and just replace the rest with three dots. That class will take any string that you put in the $cust array and remove it from the end of the $pinfo string. So I wrote this class to reuse when stuff needs to be trimmed. I needed a way to trim all white space and then a few chosen strings from the end of a string. It continues until the charlist parameter has been completely processed, one at a time, and the str string no longer contains any matches. If the characters do not match, it moves to the next character in the charlist parameter comparing once again. If the characters match, it trims it off and starts over again, looking at the "new" last character in the str string and compares it to the first character in the charlist again. Rtrim reads a character, one at a time, from the optional charlist parameter and compares it to the end of the str string. This shows how rtrim works when using the optional charlist parameter: Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?
