I have the following in a file called test_tab.txt
(tab separated):
header1 header2 header3
field1 field1a field1b; field1c
field2 field2a field2b
field3 field3a
field4 field4a field4b; field4c; field4d; field4e
field5 field5a
field6 field6a field6b; field6c
I would like to convert that to the following (also tab separated, written to another text file):
header1 header2 header3
field1 field1a field1b
field1 field1a field1c
field2 field2a field2b
field3 field3a
field4 field4a field4b
field4 field4a field4c
field4 field4a field4d
field4 field4a field4e
field5 field5a
field6 field6a field6c
field6 field6a field6c
I'm new to programming in general, but I've googled around and I think a possible way of doing this would be to create an array and somehow explode the header3 key-value pair. I'm not sure how to go about copying the fields under header1 and header2 though.
All I have at the moment is some code to create an array:
$mainarray = array();
foreach (file('test_tab.txt') as $row) {
list($header1, $header2, $header3) = explode("\t", $row);
$mainarray[] = array(header1 => $header1, header2 => $header2, header3 => $header3);
}
print_r($mainarray);
which gives:
Array
(
[0] => Array
(
[header1] => header1
[header2] => header2
[header3] => header3
)
[1] => Array
(
[header1] => field1
[header2] => field1a
[header3] => field1b; field1c
)
[2] => Array
(
[header1] => field2
[header2] => field2a
[header3] => field2b
)
[3] => Array
(
[header1] => field3
[header2] => field3a
[header3] =>
)
[4] => Array
(
[header1] => field4
[header2] => field4a
[header3] => field4b; field4c; field4d; field4e
)
[5] => Array
(
[header1] => field5
[header2] => field5a
[header3] =>
)
[6] => Array
(
[header1] => field6
[header2] => field6a
[header3] => field6b; field6c
)
)
Any ideas on how to approach this? I'm using PHP version 5.3.10.
Try this:
// read input file
$fp = fopen( 'test_tab.txt', 'r' );
// write to an output file
$fp1 = fopen( 'output.txt', 'w' );
while( ( $data = fgetcsv( $fp, '', "\t" ) ) !== FALSE ) {
$list = explode( ';', $data[ 2 ] );
foreach( $list as $column ) {
fwrite( $fp1, '"' . $data[ 0 ] . "\"\t\"" . $data[ 1 ] . "\"\t\"" . trim( $column ) . "\"\n" );
}
}
fclose( $fp1 );
fclose( $fp );
Hope this helps.
Your text must be seperated with tab and then try this one,
<?php $mainarray = array();
foreach (file('test_tab.txt') as $row) {
$ar = explode("\t", $row);
$mainarray[] = array('header1' => $ar[0], 'header2' => $ar[1], 'header3' => $ar[2]);
}
var_dump($mainarray);?>
