ignore specific line on csv file based on the fixed character

Question

I have very big csv files which contain transaction log of the bank. Valid transaction id are enclosed by <>. The format is like below

012,10/1/2013,<13273288163624>JOHN doe .,<01-10-2013>20130930,13273288163624,10/1/2013,"10,580.00",
012,10/1/2013,SI TRANSFER,10/1/2013,"11,330,114.07",
012,10/1/2013,<555395056216>JOHN DOE1,<01-10-2013>,555395056216,10/1/2013,"46,852.00",
012,10/1/2013,<13273708949197>JOHN DOE3 -,<01-10-2013>20130930,13273708949197,10/1/2013,"57,687.00",

The advantage we have is that the line which does not contain '<' and '>' need to be ignored.

Is there any way to ignore those lines of csv to have csv files contents like below?

012,10/1/2013,<13273288163624>JOHN doe .,<01-10-2013>20130930,13273288163624,10/1/2013,"10,580.00",
012,10/1/2013,<555395056216>JOHN DOE1,<01-10-2013>,555395056216,10/1/2013,"46,852.00",
012,10/1/2013,<13273708949197>JOHN DOE3 -,<01-10-2013>20130930,13273708949197,10/1/2013,"57,687.00",

I want to use csv in mssql bulk insert like below

BULK
INSERT nibl
FROM 'd:\2.csv'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n',
FIRSTROW=2
)
GO

Invalid transaction (the line without < and >) have fewer no of columns , which result in failure of bulk insert

i dont want to use loops using fgetcsv beacuse csv size is even greater than 100 mb

Answer 1

no loop just use explode,array_filter and implode

<?php
$csv=file_get_contents("1.csv");
$arr=explode("\n",$str);
function filter($str){
    return strpos($str,"<");
}
$new_arr=array_filter($arr,"filter");
$str=implode("\n",$new_arr);
file_put_contents("1.csv",$str);
?>
