      Description

      The use of operators pairs ( =+, =- or =! ) where the reversed, single operator was meant (+=, -= or !=) will compile and run, but not produce the expected results.

      This rule raises an issue when =+, =-, or =! is used without any spacing between the two operators and when there is at least one whitespace character after.

      Noncompliant Code Example

      $target = -5;
      $num = 3;
      
      $target =- $num;  // Noncompliant; target = -3. Is that really what's meant?
      $target =+ $num; // Noncompliant; target = 3
      

      Compliant Solution

      $target = -5;
      $num = 3;
      
      $target = -$num;  // Compliant; intent to assign inverse value of num is clear
      $target += $num;
