我在名为test_tab.txt的文件中有以下内容(制表符分隔)：
header1 header2 header3 field1 field1a field1b; field1c field2 field2a field2b field3 field3a field4 field4a field4b; field4c; field4d; field4e field5 field5a field6 field6a field6b; field6c
我想将其转换为以下(也是分隔符,写入另一个文本文件)：
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
我一般都是编程的新手,但我已经google了一下,我认为这样做的一种可能方法是创建一个数组并以某种方式爆炸header3键值对.我不知道怎么去复制header1和header2下的字段.
我现在所拥有的只是创建数组的一些代码：
$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);
这使：
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
)
)
关于如何处理这个的任何想法？我使用的是PHP 5.3.10版.
试试这个：
// 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 );
希望这可以帮助.
