I write PHP code to extract from Linux 'top' the server idle value and I store it in $idle. If I echo the value using php I receive this e.g.

98.5

which is correct . If I save $idle in a file in this way

file_put_contents("/usr/local/st/file, "$idle",FILE_APPEND);

and then I open the /usr/local/st/file with an editor like nano I see this

[0;10m [39;49m [1m98.5 [0;10m [39;49

as can you see it contains 98.5 but it has also a lot of undesirable chars. How to avoid it ?
