unset string offset in php

I'm trying to delete the letter p at the offset 1 of the below string. 

$str = "apb";
unset($str[0]);
var_dump($str);

I'm getting a fatal error saying Cannot unset string offsets. Any suggestions?

Solution

  • Unset is there to unset the variable:

    $str = "apb";
echo $str;
unset($str);
echo $str; // Undefined variable

    Str_replace is a easy way to do, what you want. Replace "p" with "":

    $newStr = str_replace("p", "", $str);
echo $newStr;
