关于PHP开发中的Fatal error: Call
在函数调用时参数被按照引用传递时是否发出警告。此方法已不被赞成并在 PHP/Zend 未来的版本中很可能不再支持。鼓励使用的方法是在函数定义中指定哪些参数应该用引用传递。鼓励大家尝试关闭此选项并确保脚本能够正常运行,以确保该脚本也能在未来的版本中运
在函数调用时参数被按照引用传递时是否发出警告。此方法已不被赞成并在 PHP/Zend 未来的版本中很可能不再支持。鼓励使用的方法是在函数定义中指定哪些参数应该用引用传递。鼓励大家尝试关闭此选项并确保脚本能够正常运行,以确保该脚本也能在未来的版本中运行(每次使用此特性都会收到一条警告)。
在函数调用时通过引用传递参数是不推荐的,因为它影响到了代码的整洁。如果函数的参数没有声明作为引用传递,函数可以通过未写入文档的方法修改其参数。要避免其副作用,最好仅在函数声明时指定那个参数需要通过引用传递。

版本 | 说明 |

error. |
************************************************************************************************************************************************************************************
PHP在升级到5.4版本的php可能会出现这种错误:
如果这样使用函数(或者类)的话,会产生一个 PHP Fatal error:
foo(&$var);
实际上,这样用法在php5.3中就会有提示,只是之前的仅仅会提示Deprecated而已。
