php循环选项卡分隔文件

this code works great. The only thing i can figure out how to do is convert this to an array. I have 26 to 38 rows (that number varies) what i would like to do is have it turn each row of results into its own array.

 $row[1] col1, col3, col4, col5, col8
 $row[2] col1, col3, col4, col5, col8
 $row[3] col1, col3, col4, col5, col8

I then want to be able to access each result like this: echo $row[1]; How can i do this and how do i know when the row ends?

<?php     
$a = file_get_contents( "t_rac.txt" ); 
$a = str_replace( array( "
" , "\t" ) , array( "[NEW*LINE]" , "[tAbul*Ator]" ) , $a ); 
foreach( explode( "[NEW*LINE]" , $a ) AS $lines ) {  
    foreach( explode( "[tAbul*Ator]" , $lines ) AS $li ) { 
    if (strpos($li,',') !== false) 
    {
    }
    else {
    echo $li; 
    }
    echo "<br>";
    }  
} 
?>

<?php
 //use file to get array of lines
 $arrayContent=file("t_rac.txt");
 $returnArray=array();
 $i=0;

 foreach($arrayContent as $row){
   $returnArray[$i++]=explode(",\t", $row);
 }

 ?>

As a result you have multi-dimensional array. You can use it like:

echo $returnArray[0][3]; //prints single col5 value
echo implode(",\t", $returnArray[0]); //prints col1, col3, col4, col5, col8

EDIT Make sure you have tabs between cols.

t_rac.txt content:

 $row[1]    col1,   col3,   col4,   col5,   col8
 $row[2]    col1,   col3,   col4,   col5,   col8
 $row[3]    col1,   col3,   col4,   col5,   col8

this will build a php array with the numbers 1 through 10:

$a = array();
for ($i=1; $i<=10; $i++) {
    $a[] = $i;
}

the [] notation automatically appends to the end of the array, no need for a subscript

note that php explode returns an array, so you already have the array of cols. To omit the row[] from the beginning, use array_shift($a) on the array
