Binary file problem:
I'd like to save some float values on file and read it.
<?php
//PHP Version 5.2.6-3
$valor = 12.5;
settype($valor,"float");
//⦠writing â¦
$ptrarq = fopen("./teste.bin", "wb");
fwrite($ptrarq, $valor);
fclose($ptrarq);
//... reading â¦
$ptrarq = fopen("./teste.bin", "rb");
$valor = fread($ptrarq,filesize("./teste.bin"));
fclose($ptrarq);
echo gettype($valor);
// it print "string"
?>
Why we cannot to get well a "float" or "double" value?
