When I do, I'll post an updated version of the code. I am looking into a way prevent HTML tags corruption which can happen at this time and also support BB tags like code and quote, so that they won't be counted as well. It preserves HTML tags (does not count them) and strips br tags and whitespaces at the end. The function does not wrap the text, but returns the position where to cut. I have a slightly different approach for that. What's the fastest way to trim a string to a specific number of characters, and append '.' if needed php string ellipsis truncation Share Improve this question Follow edited at 3:36 mickmackusa 43. Some people use wordwrap as long text cutter. If( $box - $box / $mult ( $box - $box / $mult ) + $size ) != ' ' & $lastspace & ( $lastspace $box = imagettfbbox ( $size * $mult, 0, $font, $text ) # Text already fits the designated space without wrapping. This operates recursively, so ridiculously long words or names (e.g., URLs or this guy's signature - ) will still keep getting broken off after they've passed the fourth or fifth lines, or whatever. If a word is too long to squeeze into the available space, it'll hyphenate it as needed so it fits the container. function substrwords($text, $maxchar, $end='.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 ?

The solution is to create a new function that will avoid cutting words apart when cutting a string by a number of characters. This example highlights the major problem with this function in that it will take no notice of the words in a string. The string variable is now set to the following. So to cut to 30 characters we would use the following. 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. The first is the string, the second is where to start cutting from and the third is the amount of characters to cut to. The ltrim () function removes whitespace or other predefined characters from the left side of a string. The substr() function has three parameters. Try it Syntax trim() Return value A new string representing str stripped of whitespace from both its beginning and end. To return a new string with whitespace trimmed from just one end, use trimStart () or trimEnd (). sounds simple, but often the results aren't as expected due to words and sentences being cut off at inappropriate points. The trim () method removes whitespace from both ends of a string and returns a new string, without modifying the original string. $string = 'This string is too long and will be cut short.' One solution is to truncate the text so that it fits on the page. For example, the following string variable, which we will cut to a maximum of 30 characters. Cutting a string to a specified length is accomplished with the substr() function.
