Parse error problem: syntax error, Unexpected T_VARIABLE

Question

I’m having trouble inserting a variable into an array... I did some research here and I couldn’t find any similar question that could help me solve this, so I’m creating this.

The mistake: Parse error: syntax error, Unexpected T_VARIABLE points to line 26

On line 26 I have this:

var $users = array('user1' => $senha);

The variable $password that is causing the error...if I put any string works without error.

Answer 1

The mistake Parse error: syntax error, Unexpected T_VARIABLE means that PHP was not expecting the definition of a variable at any given time.

This error may occur in some situations, but your question includes some special cases.

The most common problem is the absence of a semicolon in the previous line. The interpreter in this case informed the error on the next line that occurs, and not on the line where the semicolon is missing:

<?php

$var = 1
$var2 = 3;

Returns the error:

Parse error: syntax error, Unexpected '$var2' (T_VARIABLE) in path/file on line 4

Another problem is the definition of the word var before the variable in a context outside a class.

This keyword was used in PHP 4 to define class properties, and currently only exists to maintain backward compatibility with older codes.

In recent versions, he is a synonym for public.

If you are setting a variable simply remove the var.

$users = array('user1' => $senha);

Now, if you’re defining $user as a class property, the problem is that it is not possible to define dynamic values directly in the class definition (variables or functions basically), as can be observed in the documentation.

<?php
class SimpleClass
{
   // declaração de propriedade invalida:
   // ...
   public $var5 = $myVar;

}

That explains the fact that var $users = array('user1' => 'Blabla'); work.

In short

1. See if the line above the one reported in the error ends with ;

2. Do not use var in PHP 5 onwards, prefer private, protected or public.

3. If you need to define dynamic values in the class property, you can do this by the constructor method:

   <?php
   class SimpleClass
   {
   
      public $users = array();
   
      public function __construct($senha){
          $this->users = array('user1' => $senha);
   
          // ...
      }
   
   }
