In this case, $preview will be "Knowledge is a natural right of every human being". $preview = trim(mb_substr($text_truncated, 0, mb_strrpos($text_truncated, " "))) trim () - Removes whitespace or other predefined characters from both sides of a string. Related functions: rtrim () - Removes whitespace or other predefined characters from the right side of a string. $text_truncated = mb_substr($text_only_spaces, 0, mb_strpos($text_only_spaces, " ", 50)) The ltrim () function removes whitespace or other predefined characters from the left side of a string. we don't want new lines in our preview This PHP code example similar with: substr() php, php trim string to length, print only some characters of a string in php, Learning PHP programming language PHP is a general-purpose scripting language geared toward web development.

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.//The simple version for 10 Characters from the beginning of the stringīased on suggestion for checking length (and also ensuring similar lengths on trimmed and untrimmed strings): $string = (strlen($string) > 13) ? substr($string,0,10).'.' : $string 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 ?
