reading and formatting csv data using explode and arrays in php - php

Question

The Objective
To read the csv file, and separate each line into an array. The first line (field names) displayed once, and then loop through the remaining data.
I have this function to open and explode the csv file
$myFile = "csv.csv";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
$csv = explode(",", $theData);
This is the CSV file in question
id,sub,type,regprice,natprice
1,4,Team,40,75
2,4,Individual,15,35
3,4,Stunt Group,50,150
4,4,Coed Partner Stunt,50,150
What i need to know how to do, is load the first line into an array separately, then loop through the remaining arrays in the following manner.
Array[0][0] - Array[0][1] - Array[0][2] - Array[0][3] - Array[0][4]
-------------------------------------------------------------------
Array[1][0] - Array[1][1] - Array[1][2] - Array[1][3] - Array[1][4]
Array[2][0] - Array[2][1] - Array[2][2] - Array[2][3] - Array[2][4]
Array[3][0] - Array[3][1] - Array[3][2] - Array[3][3] - Array[3][4]
Array[4][0] - Array[4][1] - Array[4][2] - Array[4][3] - Array[4][4]

Answer 1

fgetcsv() will probably do all this for you.

Answer 2

Try this:
foreach ($csv as $i=>$row) {
$rowStr = implode(' - ',$row)."\n";
print($rowStr);
if ($i == 0) {
print(str_repeat('-',strlen($rowStr))."\n");
}
}
Edit: fixed syntax error.

Answer 3

<?php
$myFile = "csv.csv";
$fh = fopen($myFile, 'r');
$headers = fgetcsv($fh);
$data = array();
while (! feof($fh))
{
$row = fgetcsv($fh);
if (!empty($row))
{
$obj = new stdClass;
foreach ($row as $i => $value)
{
$key = $headers[$i];
$obj->$key = $value;
}
$data[] = $obj;
}
}
fclose($fh);
print_r($data);
?>
This will output:
Array
(
[0] => stdClass Object
(
[id] => 1
[sub] => 4
[type] => Team
[regprice] => 40
[natprice] => 75
)
[1] => stdClass Object
(
[id] => 2
[sub] => 4
[type] => Individual
[regprice] => 15
[natprice] => 35
)
[2] => stdClass Object
(
[id] => 3
[sub] => 4
[type] => Stunt Group
[regprice] => 50
[natprice] => 150
)
[3] => stdClass Object
(
[id] => 4
[sub] => 4
[type] => Coed Partner Stunt
[regprice] => 50
[natprice] => 150
)
)

Answer 4

I found this to work
I added a / at the end of the CSV lines.
$myFile = "csv.csv";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
$csvpre = explode("/", $theData);
$i = 1;
foreach ( $csvpre AS $key => $value){
$info = explode(",", $value);
if($i == "1"){
echo "$info[0] - $info[1] - $info[2] - $info[3] - $info[4]<br>";
$i++;
} else {
echo "<span style=\"color:#ff0000;\">$info[0] - $info[1] - $info[2] - $info[3] - $info[4]</span><br>";
}
}

Answer 5

$file_array=file('csv.csv');
$lines=count($file_array);
$first_line=explode(',',$file_array[0]);
$fl_text=implode(' - ',$first_line);
echo $fl_text.'<br>';
for($i=1;$i<$lines;$i++)
{
$line_text=str_replace(',',' - ',$file_array[$i]);
echo '<span style="color:#ff0000;">'.$line_text.'</span><br>';
}
This includes a couple of ways to print out the lines without needing to explode each one. You can replace the ',' with a space using str_replace, or you can explode and then implode. Probably str_replace is more efficient.
Also, the file() command reads each line of a file into values in an array.
