Hi all,
I have a need to iterate through a multibyte string to process the string
character by character. Hopefully in php6, this will work without any special
work, but as we know we need to use special multibyte string functions in php5
to work with utf-8 characters. Here's an example that iterates my dilemma:
<?php
mb_internal_encoding("UTF-8");
$str = "string with utf-8 chars åèö";
$length = mb_strlen($str);
$brokenStr = "";
$preservedStr = "";
for ($i = 0; $i < $length; $i++) {
$brokenStr .= $str[$i];
$preservedStr .= mb_substr($str, $i, 1);
}
echo "brokenStr = " . $brokenStr . "\n";
echo "preservedStr = " . $preservedStr . "\n";
?>
The array notation for string is the normal way to do this with regular
strings: $str[$i]. I assume this will work for multibyte strings in php6.
-- Is using mb_substr($str, $i, 1) the only way to get this to work in php5?
That's my question.
It seems like it's going to be many times slower according to some of the
comments I've seen on the multibyte functions in the php manual.
Thanks!!
