How to specify a specific delimiter when reading a text file from PHP?

I have a text file, I am told the delimiter is as quoted below. My question is how to I set the delimiter inside PHP?

ie this would开发者_如何学Python set it as TAB delimiter in my script

$csv->delimiter = "\t";   # tab delimited

Field Separator (FS): SOH (ASCII character 1)

Record Separator (RS) : STX (ASCII character 2) + "\n"

For example, these characters are represented in programming languages as shown below:

Perl:

$field_separator = chr(1); 
$record_separator = chr(2) . "\n";

Java:

String fieldSeparator = String.valueOf((char)1); 
String recordSeparator = String.valueOf((char)2) + "\n";

A sample of the file looks like this:

#export_datecollection_type_idname
#primaryKey:collection_type_id
#dbTypes:BIGINTINTEGERVARCHAR(200)
#exportMode:FULL

There is also the chr() function within PHP. So you should be able to use the same syntax as in PERL:

$field_separator = chr(1); 
$record_separator = chr(2) . "\n";

Have you tried it out, or do you have another issue? Or do you want to create a file like that in PHP?
