CSV not properly being parsed on new lines - php

Question

I have a CSV file that looks like:
Header1,Header2,Header3
value1,value2,value3
value11,value12,value13
value21,value22,value23
etc...
When I use this code to parse through it:
$csvData = file_get_contents($file_url);
$lines = explode(" ", $csvData);
$array = array();
foreach ($lines as $line) {
$array[] = str_getcsv($line);
}
dpm($array);
the first value of a line always ends up being part of the end of the last header:
EDIT: There must have been an issue with cache as this is working fine.

Answer 1

For reading CSV file explode() and file_get_contents() are not the correct options. Go for fgetcsv
You can do like below for reading CSV file:
<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
?>

Answer 2

Use file instead of file_get_contents. That will return an array with one line of the input file on each index. This will work with all possible new line characters.
$lines = file($file_url, FILE_IGNORE_NEW_LINES)

Answer 3

You might want to break lines into newlines ("\n") instead of just spaces (" "). Even better, you might want to use file() to load file lines into an array. Better yet, you might want to use SplFileObject class to do that:
<?php
$file = new SplFileObject($file_url);
$file->setFlags(SplFileObject::READ_CSV | SplFileObject::SKIP_EMPTY
| SplFileObject::DROP_NEW_LINE | SplFileObject::READ_AHEAD);
$data = array();
foreach ($file as $row) {
$data[] = $row;
}
Good luck!
