Few lines of C++ to PHP

[jenkinsp]

Hey,

How would i do this in php ? (from borland c++)

for (int i=1; i<=myString.Length(); ++i)
{
returnValue += StrToInt(AnsiString("0x" +
(AnsiString)myString[i]));
}
--
thanks

I think you are trying to convert hexadecimal number to decimal, then
add them together.
<?php
$temp = str_split($myString);
$returnValue = 0;
foreach($temp as $each) $returnValue += hexdec($each);
?>

Hope that helps

Try something like this:

<?
$returnValue = 0;
$myString = 'ABCDEF';

for ($i=1;$i<=strlen($myString);$i++)
{
$returnValue += hexdec($myString[$i]);
}

echo $returnValue;
?>

Correction to my code:

>for ($i=1;$i<=strlen($myString);$i++)

That should be:

for ($i=0;$i<strlen($myString);$i++)

(I didn't realise string indexes started at 1 in C and not 0 like PHP)

Just a general performance note: In this case strlen() will be called
again in each iteration, which can become an issue in a long-running
loop or with a more complex expression.

The value to check against should be put in a variable instead before
entering the loop, e.g.

for ($i = 0, $l = strlen($myString); $i < $l; $i++) {
...
}
