I'm trying to do a simple PHP function to put a .csv file into a database. The problem is that the files are delimited with a semicolon and for some reason when a cell contains a comma it leaves out everything after it.
For example the .csv file
manufacturer;comment;year
toyota;good car, bad color;1997
comes out as the following when printed with the print_r() function
[0] => Array
(
[0] => manufacturer
[1] => comment
[2] => year
)
[1] => Array
(
[0] => toyota
[1] => good car
)
Edit
Here's the code I'm using.
//get the contents of the .csv file
$filepath = './files/csvfile.csv'
$fileopen = fopen($filepath,"r");
//create an empty array
$csv = array();
//go through the .csv file with fgetcsv()
while(($line = fgetcsv($fileopen,";")) !== FALSE)
{
$line = explode(";",$line[0]);
$csv[] = $line;
}
//print the result
echo "<pre>";
print_r($csv);
echo "</pre>";
fclose($fileopen);
Put the delimiter as the 3rd argument
http://php.net/manual/en/function.fgetcsv.php
while(($line = fgetcsv($fileopen, 0, ";")) !== FALSE)
I don't think you need that explode line either.

I am in the process of turning this CSV File of quotes to a HTML Table. The CSV Table is formatted as such:
The old world is dying, and a new world struggles to be born; now is the time of monsters.|Antonio Gramsci|1891-1937
The unexamined life is not worth living.|Socrates|c.469-399 B.C.
When converting it to an array by
<?php
$file = fopen("quotes.csv", "r");
$data = fgetcsv($file, 1000, "|");
$arr = [];
while (($data = fgetcsv($file, 1000, "|")) !== false) {
$arr[] = $data;
}
echo "<pre>";print_r($arr)
?>
1st Row gives me
[0] => Array
(
[0] => The old world is dying, and a new world struggles to be born; now is the time of monsters.|Antonio Gramsci|1891-1937|
Whereas 2nd row Correctly Gives me this output
[1] => Array
(
[0] => The unexamined life is not worth living.
[1] => Socrates
[2] => c.469-399 B.C.
)
How can I make the first row give me the output of the 2nd row? I know it has something to do with that comma in the first column but how do I work around that?
I have a .csv file with list of bank numbers and bank names like this
10000000;BBk Berlin
10010010;Postbank Berlin
10010111;SEB Berlin
10010424;Aareal Bank
.......
and when I use fgetscv() like this:
$filename = bank.csv;
if (file_exists($filename) && $file = fopen($filename, "r")) {
while( !feof($file) ) {
print_r(fgetcsv($file));
}
}
This will get me an array with single key like this
Array
(
[0] => 10000000;BBk Berlin
)
Array
(
[0] => 10010010;Postbank Berlin
)
Array
(
[0] => 10010111;SEB Berlin
)
Array
(
[0] => 10010424;Aareal Bank
)
And what i want is this:
Array
(
[0] => 10000000 [1] => BBk Berlin
)
So that the bank name is a separate key in array. How can i achieve this? Maybe fgetcsv() is not the right function for me?
The third parameter of fgetcsv is the delimiter, so you must set it accordingly
fgetcsv($file, 0, ';')
Your problem is, that fgetcsv uses , comma as delimiter by default. You need to change it to ; semicolon. Then you won't need to explode anymore :)
function process_csv($file) {
$file = fopen($file, "r");
$data = array();
while (!feof($file)) {
$data[] = fgetcsv($file,null,';');
}
fclose($file);
return $data;
}
Hi In another post I learned how to read data from a text file into an array. After the script reads the text file here is the resulting array of data.
What I'm trying to do is simply return the 'key' or record number where a search string appears i.e. if I pass the parameter 'muscle3' it should return '3' because it is the third 'row' in the table
Then I can easily extract the other columns with $arrayTable[$keyVal][2] and $arrayTable[$keyVal][3]
As you can see the pageName which is the search field is stored in $arrayTable[$keyVal][2]
By getting the $keyValue from a search, i can then get the other pages.
i.e. mygreatwebsite.com/?page=muscle3
it then fetches the data from the array and it
But when I run the script below it gives the following error message
"Warning: Invalid argument supplied for foreach()"
$page=$_REQUEST['page'];
$keyVal = searchForId($page,$arrayTable); // this is the value I want returned
function searchForId($id, $array) {
foreach ($array as $key => $val) {
print_r ($val); print "<br><br>";
if ($val === $id) {
return $key;
}
}
return null;
here is the output from the above script
Array ( [0] => muscle1 [1] => arrayField [2] => description )
Array ( [0] => muscle2 [1] => arrayField2 [2] => description )
Array ( [0] => muscle3 [1] => arrayField3 [2] => description )
Can someone help me figure this one out? Thanks!
Someone asked how the array table is being defined: here it is
$i=0;
if (($handle = fopen($inputFile, "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$arrayTable[$i] = $data; $i++;
}
fclose($handle);
}
input file is a CSV file with the first row containing column headings and each subsequent row containing data
the first column is called 'pageName'
What I'm seeking to do is 'search' for the 'pageName' and just return which record.
i.e. Muscle 1 is in record #1 muscle3 is is record #3
its a simple example - the CSV file is much more complex that this.
I am fairly new to php and got this from a stack overflow question and cant seem to get it to work for me.
<?php
if (($handle = fopen("fullbox.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
echo "<pre>".print_r($data)." <br /></pre>";
}
fclose($handle);
}
echo $data[1];
?>
I need to set up a couple arrays for pricing using a large number of products(which I can pull from my csv file) Fullbox.csv consists of just 10 numbers with 2 decial places. I have just been trying to test this and this is the output that I get:
Array
(
[0] => 8.53
)
Array
(
[0] => 4.74
)
Array
(
[0] => 5.00
)
Array
(
[0] => 2.50
)
Array
(
[0] => 6.48
)
Array
(
[0] => 3.99
)
Array
(
[0] => 8.53
)
Array
(
[0] => 4.74
)
Array
(
[0] => 8.53
)
Array
(
[0] => 4.74
)
Why is the array setting all values in the [0} place holder of the array and also why is there a 1 in between each line. Thanks in advance.
Update If this is a ten item array this should then return the value of the 1 entry in the array but it doesn't. I essentially just need to store all of the prices so I can use them as variables later. I don't need them to be printed. Thanks again.
echo $data[1];
print_r does not return the formatted array by default; it outputs it and returns 1. Pass true as a second parameter.
echo "<pre>".print_r($data, true)." <br /></pre>";
All the values are in the 0 index of the array because arrays start at 0. There is nothing wrong there.
Try this:
$f = fopen(yourfile, "r");
$fs = filesize(yourfile);
$content = fread($f, $fs);
$lines = explode("\n", $content);
$result = array();
foreach($lines as $line) $result[] = explode(",", $line);
CSV as in Comma Seperated-Values is an array each line. So each line -even if it has only 1 value- is array.
Also you don't need to echo "print_r".
you also read the data from the CSV using the following function and sort using the usort() function.

Read data from the CSV
function readCSV() {
$csv = array_map('str_getcsv', file('data.csv'));
array_shift($csv); //remove headers
$csvData = splitandSort($csv);
createCSV($csvData);
}
I have a csv file which has a word for each row like this
word1
word2
word3
And have the following code to read the data:
$arr = array();
$fh = fopen('path/to/file', 'r');
while (($rows = fgetcsv($fh)) !== false) {
print_r($rows);
if (!in_array($rows[0], $arr))
$arr[] = "'".trim($rows[0])."'";
}
fclose($fh);
print_r($arr);
The problem is im getting empty strings/null for $rows[0] and im quite sure the data is there.
Array ( [0] => )
Array ( [0] => )
Array ( [0] => )
Array ( [0] => '' [1] => '' [2] => '' [3] => '' )
Any help would be greatly appreciated.
You're trying to read the words into an array? Replace all that with just:
$arr = file('/path/to/file');
print_r($arr);
Cannot reproduce. I'm assuming there is something wrong with your file format. Most likely there is an empty line on top (which I'm not quite sure, but might fail the !== false test).
Better try:
$arr = array_map("str_getcsv", file("words.csv"));
print_r($arr);
And if you need to re-add the quotes, do a separate loop.
The file reading part has already been answered, but about your loop to add the quotes, you could use array_walk():
function add_quotes(&$item)
{
$item = "'" . $item . "'";
}
array_walk($arr, "add_quotes");
