Need to try and simplify my code possibly into two functions and I want to be able to use substr and strpos and store them into an array?

[Mconnolly86212]

Here's the code so far, essentially I want to. E able to take the text file that has numbers and commas and remove the commas, not happy with it would rather it be simpler in a away but with out the use of explode. Any help would be brilliant. Thank you

 

 

 

 

<?php

//linking table to form

$studentid=$_POST["id"];

 

//To print out student ID

echo "You have selected Student ID: $studentid <br />";

 

 

//define what the file equals to which is the students ID

$file = "$studentid.txt";

 

//Opening the selected files

$fileopen = fopen($file,'r') or die("Sorry, cannot open $file");

if($fileopen){

 

while (($buffer=fgets($fileopen,4096))!==false){

// echo $buffer."<br/>";

}

if(!feof($fileopen)){

echo "Error:unexpected fgets() fail\n";

 

}

fclose($fileopen);

}

 

//remove all commas from txt file

$filearray=file("$studentid.txt");

$count=count($filearray);

 

for($i=0; $i<$count; $i++){

 

$startnum=0;

$stringlength = strlen($filearray[$i]);

$comma = strpos($filearray[$i], ",", $startnum);

$array[$i][0] = substr($filearray[$i], $startnum, $comma);

$j=1;

 

while ($j<$count-1){

$comma = strpos($filearray[$i], ",", $startnum);

$comma2 = strpos($filearray[$i], ",", $comma+1);

$sub = $comma2-$comma;

$num = substr($filearray[$i], $comma+1, $sub -1);

$startnum = $comma2;

$array[$i][$j]= $num;

 

$j++;

}

$stop = $stringlength - $comma2;

$array[$i][$j] = substr ($filearray[$i], $comma2 + 1, $stop);

}

 

function array_transpose($filearray)

{

array_unshift($filearray, NULL);

return call_user_func_array('array_map', $filearray);

}

 

//table heading

echo"<h1>The Table</h1>";

 

//creating the rows and columns for the txt file

echo "<table border = 1 >";

for($row=0; $row<$count; $row++){

print "<tr>";

 

for($col=0; $col<$count; $col++){

print "<td>".$array[$row][$col]."</td>";

}

}

echo "</table>";

 

 

 

//table heading

echo"<h1>Transpose</h1>";

 

?>

If you have a file with comma separated data, use fget_csv

 

$array = [];
$fp = fopen('students.txt', 'r');
while ($line = fget_csv($fp)) {
    $array[] = $row;
}
