大佬教程收集整理的这篇文章主要介绍了PHP实现的json类实例,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
本文实例讲述了PHP实现的json类。分享给大家供大家参考。具体如下:
这里注意json_encode只有(PHP 5 >= 5.2.0,PECL json >= 1.2.0)才有
PHP;"> <>PHP /* vim: set expandtab tabstop=4 shiftwidth=4 softtabstop=4: */ /** * Converts to and from JSON format. * * JSON (JavaScript Object Notation) is a lightweight data-interchange * format. It is easy for humans to read and write. It is easy for machines * to parse and generate. It is based on a subset of the JavaScript * Programming Language,Standard ECMA-262 3rd Edition - December 1999. * This feature can also be found in Python. JSON is a text format that is * completely language independent but uses conventions that are familiar * to programmers of the C-family of languages,including C,C++,C#,Java,* JavaScript,Perl,TCL,and many others. These properties make JSON an * ideal data-interchange language. * * This package provides a simple encoder and decoder for JSON notation. It * is intended for use with client-side Javascript applications that make * use of HTTPRequest to perform server communication functions - data can * be encoded into JSON notation for use in a client-side javascript,or * decoded from incoming Javascript requests. JSON format is native to * Javascript,and can be directly eval()'ed with no further parsing * overhead * * All strings should be in ASCII or UTF-8 format! * * LICENSE: Redistribution and use in source and binary forms,with or * without modification,are permitted provided that the following * conditions are met: Redistributions of source code must retain the * above copyright notice,this list of conditions and the following * disclaimer.
