"start boş, stop -, step dolu, step 1" } elseif (( ord ( substr ( $string, $i, 1 )) 128 ) & ( $count = $start )) Second character position is 1, and so on.ģ.$byte is one character length of your encoding, For example: utf-8 is "3", gb2312 and big5 is "2".you can use the function strlen() get it. ġ.Use it like this bite_str(string str, int start, int length ) Ģ.First character's position is 0. It can performs multi-byte safe on number of characters. This returns the portion of str specified by the start and length parameters. ![]() May be by following functions will be easier to extract the needed sub parts from a string: $string = 'This is a sentence of text.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 ?

Yet another methods is to use the PHP explode() and list() functions. $string = 'This is a sentence of text.' $output = substr ( $string, 0, strpos ( $string, ' ' )) print ( $output ) This It is slightly less favourable since it has to be used with the strpos() function to find the first occurrence of a particular character in the string. The PHP substr() function is another way to get the substring before a space. $string = 'This is a sentence of text.' $output = strstr ( $string, ' ', true ) print ( $output ) This ![]() ![]() If true is supplied as the third argument the substring before a character will be returned. The default behaviour of this function is to return the substring of a string after the first match of a character. $string = 'This is a sentence of text.' $output = strtok ( $string, ' ' ) print ( $output ) ThisĪnother clean way of achieving the same result is to use the PHP strstr() function. ![]() Pass the string to check as the first argument and the character to look for as the second. The easiest way to get a substring before the first occurrence of a character such as a whitespace is to use the PHP strtok() function. We will explore some of the best methods in this tutorial so you can determine which one best fits your specific scenario. There are few different ways we can return the portion of a string before the first occurrence of a character in PHP.
