A character from a string
You can get a specific character from a string as if the string was an array.
< ?php
$s = 'PHP';
echo $s[0]; // will print "P"
?>
This syntax may be confusing, because someone looking at the code might expect that $s is an array. Well it is an array, an array of characters, but that's not the point. The point is that if might be confusing.
The same result may be achieved with curly braces.
< ?php
$s = 'PHP';
echo $s{1}; // will print "H"
?>
The numbering is zero-based, the first character in the string has offset 0.
