PHP - backspace in file with fwrite

Question

I can't put a backspace in a File I try with:

fwrite($file, "\tpublic static function byPk(");
foreach ($pk as $column)
    fwrite($file, "\$" . $column->name . ", ");
fwrite($file, "\x08");

But the result in the file is:

Any solution? Thanks! :D

Can you `var_dump($column->name)` so we can see what's in there? Looks like a problem in charsets — Machavity, Mar 30 '15 at 01:05

A solution is to use fseek() to go backward. http://php.net/manual/fr/function.fseek.php

You can also make an array with your columns names and implode them.

And if is another way? What happend if is in the end of file?? and I want to remove the last character? Is possible to make a backspace ?? – jtwalters Mar 30 '15 at 01:41
In your case it will never be the end of file because you need to backward 2 characters and add a parenthesis... If the parenthesis is the end simply add a whitespace after ? EDIT: It's not possible to 'backspace' because it's a character too... – fdglefevre Mar 30 '15 at 01:47
So the best way is put all string in a $var and cut the string and put in the fwrite o: ?? – jtwalters Mar 30 '15 at 02:14
And what do u think is the best way in efficiencity? – jtwalters Mar 30 '15 at 02:28
I think do: fseek($file, -2, SEEK_END ) before writing fwrite($file, ")") – fdglefevre Mar 30 '15 at 02:38
Thanks! I go to use that :D – jtwalters Mar 30 '15 at 03:42
