FileReadLine( <file>, <expression> )
Contents |
Description
Read a line of text from a previously opened text file (Or specify a name of a file).
Parameters
file
A variable containing the File handle OR a name of a file to open.
expression
Optional; Line number to read default is line 0 (0 means the first line).
Return Value
Success: Returns a string
Failure: Returns 0 if error occurs.
Remarks
Trailing newlines "\n" and "\r" will be removed from the end of the returned string automatically.
Example
$File = FileOpen("MyFile.txt", "r"); If(isObj($File, "file")) { $Line0 = FileReadLine($File, 0); $Line1 = FileReadLine($File, 1); $Line2 = FileReadLine($File, 2); println( "Line0: " . $Line0 ); println( "Line1: " . $Line1 ); println( "Line2: " . $Line2 ); FileClose( $File ); }
Heres an example of using it directly with a text file by name :
$Line0 = FileReadLine("MyFile.txt", 0); $Line1 = FileReadLine("MyFile.txt", 1); $Line2 = FileReadLine("MyFile.txt", 2); println( "Line0: " . $Line0 ); println( "Line1: " . $Line1 ); println( "Line2: " . $Line2 );
