Cannot assign an empty string to a string offset

Question

I\'ve just installed PHP 7.1 and now I am seeing this error :

PHP Warning:  Cannot assign an empty string to a string offset in /postfixadmin/variables.inc.php o         


        

Answer 1

According to bug #71572 it's not permitted to assign empty string. Then use:

substr(fDomains,1); //like Kris Roofe wrote;

or use solutions like this:

$fDomainsTmp = $fDomains;
for($x = 0 ; $x < length($fDomains); $x ++){
    if(condition character allow in string){ 
      $fDomainsTmp .= $fDomains[$x]; 
    }
}
$fDomains = $fDomainsTmp;
