Pretty new to PHP. I have a csv feed that i am trying to display every line of in the right place. The feed is loaded into a multidimentional array and I can echo out specific places like this.
echo $readcsv[0][2]
But I am trying to use the value of the variable $row in stead of the first number while doing a while loop.
Something like:
echo $readcsv[$row][2]
I have tried next(), str_replace() and strtr() but none of them seems to work while the loop is running.
$row = 1;
$readcsv = array();
if (($handle = fopen("file.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
$num = count($data);
echo $readcsv[$row][2];
$row++;
for ($c=0; $c < $num; $c++) {
}
$mycsvfile[] = $data;
}
fclose($handle);
}
CSV file:
title;image_link;link;empty;price;
1;back.gif;http://link.com;;19.95;
2;back.gif;http://link.com;;19.95;
3;back.gif;http://link.com;;19.95;
4;back.gif;http://link.com;;19.95;
5;back.gif;http://link.com;;19.95;
I am not quite sure from your code and question exactly what you are trying to do, but maybe its something like this
if (($handle = fopen("file.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
// you load the line into $data and its a one dimentional array
// occurance 2 is the `link` (http://link.com) if that what you want to echo
echo $data[2];
// as you have a loop, maybe you were trying to
// echo each fields from the csv so you can do that like this
foreach ($data as $idx => $value) {
echo "Column $idx = $value";
}
$mycsvfile[] = $data;
}
fclose($handle);
}

So I have this code that takes each cell from a google sheets file but It echoes them one at a time. I need to concatenate them into one string and pass that string to a js script so I need to echo them all at once. I don't know much php so I'm having a hard time deciphering the echo line.
You can define a variable and append strings to it:
<?php
// link to Google Docs spreadsheet
$url='https://docs.google.com/spreadsheets/d/1_4d-MPxTUOVZbxTOlhjXv1ebTlBPQ-_JrYUlS1rqX5Q/pub?output=csv';
// Define variable which will hold your data.
$html = "";
// open file for reading
if (($handle = fopen($url, "r")) !== FALSE)
{
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
$totalrows = count($data);
for ($row=0; $row<=$totalrows; $row++)
{
if ( (strlen($data[$row])>0))
{
// Append your data to $html variable
$html .= '<dt><span class="icon"></span>'.$data[$row].'</dt><dd>'.$data[$answer].'</dd>';
}
}
}
fclose($handle);
}
//Do whatever you want with $html variable.
?>
I'm trying to take a file of id numbers and find the names associated with those numbers from a different file and print a csv in the form id,name.
The Def.csv file is in the form
1;128;34;64;Uppland,
2;0;36;128;Östergötland,
3;128;38;192;Småland,
WIth the first number being the ID and the last field the name.
The IDs.csv is just IDs in no specific order with a comma and new line. ie.
12, \n
Here's the (updated, bad) script:
<?php
$ID;
$names;
$both = array();
$row = 0;
echo ("1\n");
if (($handle = fopen("IDs.csv", "r+")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$ID[$row] = $data[0];
$row++;
//print_r($ID);
}
}
print_r($ID);
fclose($handle);
if (($handle = fopen("Defs.csv", "r+")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
$Names = $data[4];
// DEBUG, works// echo "$Names";
}
}
fclose($handle);
for ($c = 0; $c < $row; $c++)
{
$Both[$ID[$c]] = $Names[$ID[$c]];
}
foreach ($Both as $key => $value)
{
echo "$key,$value\n";
}
?>
This is my current output
Array
(
[0] => 2
[1] => 3
[2] => 1
)
2,t
3,l
1,u
for the small test case here it should be 2,Östergötland 3,Småland and 1,Uppland
I'm just wondering is it possible to have a csv file (with many values) and scan the file for a specific value with php?
Ideally if this is possible, Id also like to get the index of that value in the file (i.e what row number the value falls on).
I'm quiet new to php so I'm not sure where to start.
All help is greatly appreciated.
Sure,
Not tested:
<?php
$search = 'mysearchstring';
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE)
{
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE)
{
$num = count($data);
$row++;
for ($c=0; $c < $num; $c++)
{
if ($data[$c] == $search)
{
echo "Found in row $row in column {$c+1} <br />\n";
}
}
}
fclose($handle);
}
?>
I have data in csv file as follows.
Mr,Vinay,H S,Application Engineer,vinay.hs#springpeople.com,99005809800,Yes
Mr,Mahammad,Hussain,Application Engineer,vinay.hs#springpeople.com,99005809800,Yes
I want to store each row in each array.explain me how to do that
I did not understand each row in each array.
use fgetcsv() function to read the CSV file php.
An example
<?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);
}
?>
OR
If you want to store them in an array you could use
$data = array();
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while(($row = fgetcsv($handle, 1000, ",")) !== FALSE) {
$data[] = $row;
}
}
Assuming the CSV is a file (if not, make the CSV match the $csv, which is essentially the file broken down in the separate lines), here is a very simple way:
$csv = file('mycsv.csv'); $result = array();
//iterate the lines
foreach ($csv as $line)
// I'd recommend more robust "csv-following" method though (fgetcsv maybe)
$result[] = explode(',',$result);
//show the results
print_r($result);
Though fgetcsv is probably a safer bet (as others have mentioned) (See the docs).
To further extend your comment:
//iterate the lines
foreach ($csv as $line)
// I'd recommend more robust "csv-following" method though (fgetcsv maybe)
$result[] = explode(',',$result);
can become:
//iterate the lines
foreach ($csv as $line)
// combine the current results with the new results
$result = array_marge($result,$line);
or, if order is important:
//iterate the lines
foreach ($csv as $line)
// add each result on to the end of the result array
foreach($line as $val)
// add each value
$result[] = $val;
You can use fgetcsv() for that:
$data = array();
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while(($row = fgetcsv($handle, 1000, ",")) !== FALSE) {
$data[] = $row;
}
}
Im trying to figure out how to take the data returned by fgetcsv, and format it into a readable/editable table, and then use fputcsv to save that table
so far i have this
<?php
$row = 1;
$handle = fopen("csv.csv", "r");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "\n";
}
}
fclose($handle);
?>
The following code will output the CSV in an html table. To make it editable wrap the echo ..$val.. with tags and add a php form handler that takes the result and reforms a CSV
<?php
$row = 1;
$handle = fopen("csv.csv", "r");
echo("<table>");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
echo("<tr>\r\n");
foreach ($data as $index=>$val) {
echo("\t<td>$val</td>\r\n");
}
echo("</tr>\r\n");
}
echo("</table>");
fclose($handle);
?>
