提供彈性的授權條款，使您的產品更具吸引力、增加銷售量並提高客戶滿意度
提高從評估到授權產品的轉換率
防止其他人更改您的代碼（所有文件都被設為不可編輯，外部更改會破壞代碼），進而保護文件免受外部篡改
防止透過PHP編碼和混淆進行逆向工程
You worked hard to develop your code. Now you need to protect it. Zend Guard's powerful encoding and obfuscation technologies prevent reverse engineering, copyright infringement and unauthorized modification of your code. Encoding is a process where the PHP source code is converted to an intermediate machine readable format, just like PHP encryption. This format is hard for humans to read and convert back to source code. As a result it protects your code from casual browsing. This means that if people obtain access to your site's code they will not be able to use that for unintended purposes. Obfuscation is a process where the code is intentionally made very hard to read as source code or as reverse engineered code. This obfuscation is designed to manage risks that stem from unauthorized access to source code. These risks include loss of intellectual property, ease of probing for application vulnerabilities and loss of revenue that can result when applications are reverse engineered, modified to circumvent licensing and then recompiled. Although reverse engineering always existed in computer software, it is especially important for in computing environments such as PHP which take advantage of dynamic processing of language elements rather than code which has been compiled into machine language before being deployed.
保護您的PHP代碼免受未經授權的使用
Zend Guard's licensing capabilities allow Independent Software Vendors (ISVs) to create a variety of licensing policies for their commercial PHP applications. The product supports most commonly used licensing models such as concurrent users, time limited, segment of network, or server specific licensing. These capabilities allow vendors to maximize their revenue by preventing unauthorized use.
Compiles and converts the plain-text PHP scripts into a platform-independent binary format known as a 'Zend Intermediate Code' file. These encoded binary files can then be distributed instead of the plain text PHP protecting your hard programming efforts. Benefits of using this PHP encrypt process:
Zend Guard授權管理既加強保護，也增加營收機會。
The license file, deployed along with the encoded PHP, is validated at runtime. Licenses can be easily modified or renewed, without the need to deploy new software. Vendors can pick-and-choose from a variety of flexible licensing models:
