PHP Parse error: syntax error, unexpected T_PUBLIC
提问by Ashish Yadav
I am getting this error in this PHP code on line 3, what could be wrong? This code has been taken from php manual user notes by frank at interactinet dot com
我在第 3 行的此 PHP 代码中收到此错误，可能有什么问题？此代码已从交互网络点 com 上的弗兰克 (frank) 的php 手册用户注释中获取
<?php
public function myMethod()
{
return 'test';
}
public function myOtherMethod()
{
return null;
}
if($val = $this->myMethod())
{
// $val might be 1 instead of the expected 'test'
}
if( ($val = $this->myMethod()) )
{
// now $val should be 'test'
}
// or to check for false
if( !($val = $this->myMethod()) )
{
// this will not run since $val = 'test' and equates to true
}
// this is an easy way to assign default value only if a value is not returned:
if( !($val = $this->myOtherMethod()) )
{
$val = 'default'
}
?>

The publickeyword is used only when declaring a class method.
该public关键字仅在声明类方法时使用。
Since you're declaring a simple function and not a class you need to remove publicfrom your code.
由于您声明的是一个简单的函数而不是一个类，因此您需要public从代码中删除。

You can remove public keyword from your functions, because, you have to define a classin order to declare public, private or protected function
您可以从函数中删除 public 关键字，因为您必须定义一个类才能声明public、private 或 protected 函数
