Today the topic of the Italian PHP Mailing List was the following: String access and modification by character in PHP
Characters within strings may be accessed and modified by specifying the zero-based offset of the desired character after the string using square array-brackets like $str[42] so think of a string as an array of characters.
Note: They may also be accessed using braces like $str{42} for the same purpose. However, using square array-brackets is preferred because the {braces} style is deprecated as of PHP 6.
So Matteo B. posted this:
error_reporting(E_ALL|E_STRICT);
$var = 'Hello';
$var[1] = 'World';
var_dump($var);The result is the following:
string(5) "HWllo"
We're all scared.
