How do i simply write out a file including real tabs inside? tab means real tab which is not the spaces. How to write the tab or what is the character for real tab?
For example here:
$chunk = "a,b,c";
file_put_contents("chunk.csv",$chunk);
What character should i use to get tabs instead of Commas (,) there?
In the output file, there should be real tabs between the seperated words.
- Real Tabs means, a true wide space we get when we press the
<tab>key in a text-editor.
The tab character is \t. Notice the use of " instead of '.
$chunk = "abc\tdef\tghi";
If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:
...
\t horizontal tab (HT or 0x09 (9) in ASCII)
Also, let me recommend the fputcsv() function which is for the purpose of writing CSV files.
Use \t and enclose the string with double-quotes:
$chunk = "abc\tdef\tghi";
This should do:
$chunk = "abc\tdef\tghi";
Here is a link to an article with more extensive examples.
