I have a file that has the following structure :
I'm trying to insert a new line at the end using this function :
ini_set('auto_detect_line_endings',true);//At the beginning of the php file
$handle = fopen("File.csv", "r+");
$line = array(
[0] => Trussville
[1] => L01
[2] => 8765
[3] => this is , a sample (xx)
);
fputcsv($handle, $line, ',', '"');
fclose($handle);
The result I get is as following :
Can help me please ?
Thanks
before writing, position the file pointer to the end of the file, like so:
...
fseek($handle, 0, SEEK_END);
fputcsv($handle, $line, ',', '"');

I have an array something like below:
Array
(
[0] => IA62b066
[1] => IAca99de
[2] => IAafed13
[3] => IA49882c
[4] => IA5c9872
[5] => IA39b3e1
I want to export the only the value from this array to text file. Txt file should display data like this.
IA62b066
IAca99de
IAafed13
IA49882c
IA5c9872
IA39b3e1
I have tried many ways but I could not solve it.
file_put_contents("output/$fileName.txt", print_r($array, true));
Can anybody please help me solve it.
That will create test.txt file in the directory of php script with the content of the array.
<?php
$input = [
'IA62b066',
'IAca99de',
'IAafed13',
'IA49882c',
'IA5c9872',
'IA39b3e1'
];
$filePath = __DIR__ . DIRECTORY_SEPARATOR . 'test.txt';
$content = implode(PHP_EOL, $input);
file_put_contents($filePath, $content);
Try this:
<?php
$myfile = fopen("newfile.txt", "w") or die("Unable to open file!");
foreach($your_array as $value){
fwrite($myfile, $value . '\n');
}
fclose($myfile);
?>
I am new to PHP and working to get some results but failing to achieve my target. I have text file which contains data like this,
APAC|AU|enable|SYD1925|8|20150929|WORKING
APAC|AU|disable|ADL7235|3|20120123|RESIGNED
APAC|NZ|disable|NZ1356|6|20110123|RESIGNED
APAC|NZ|enable|NZ1356|3|20130123|WORKING
I am trying to search "AU" && "enable" for this text, line by line and I am a bit successful in it. Here is my Code example;
public function scan1()
{
$file = FCPATH.'uploads/example.txt';
// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
$search1 = "AU";
$search2 = "enable";
$lines = file($file);
foreach($lines as $line)
{
if(stristr($line,$search1) && stristr($line,$search2))
echo $line;
}
}
Now, I am trying to explode/split output data and assign variable / array to save in database but I am failing to do so, can someone please help or give me some direction to achieve this. Thank you
Please show us your_table scheme.
If '$db' is a handle of the db connection :
foreach($lines as $line)
{
if(stristr($line,$search1) && stristr($line,$search2))
{
$arr = explode("|", $line);
$query = "INSERT INTO your_table VALUES ('".$arr[0]."', '".$arr[1]."', '".$arr[2]."', '".$arr[3]."', '".$arr[4]."', '".$arr[5]."')";
$db->query($query);
}
}
First, obtain the file contents with file_get_contents:
$str = file_get_contents(FCPATH.'uploads/example.txt');
Then, use the regex (preg_match_all) to find all portion of text you're looking for:
preg_match_all("/APAC\\|(\w{2}\\|\w+)/", $str, $matches);
Then adapt the array so the 'AU' and 'enabled' are separated (array_map, explode):
$matches = array_map(function ($v) { return explode('|', $v); }, $matches[1]);
So, print_r($matches); returns:
Array
(
[0] => Array
(
[0] => AU
[1] => enable
)
[1] => Array
(
[0] => AU
[1] => disable
)
[2] => Array
(
[0] => NZ
[1] => disable
)
[3] => Array
(
[0] => NZ
[1] => enable
)
)
Finally, the foreach loop:
foreach($matches as $k => $kv)
{
$search1 = $kv[0]; // AU
$search2 = $kv[1]; // enabled
}
This works as expected:
public function scan1()
{
$file = FCPATH.'uploads/example.txt';
// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
$search1 = "AU";
$search2 = "enable";
$lines = file($file);
foreach($lines as $line)
{
if(strpos($line,$search1) !== false && strpos($line,$search2) !== false)
echo $line;
}
}
using strpos function for detection.
my_custom_table:
id int(11)
product_type varchar(210)
product_serial varchar(210)
created_at datetime
//Upload CSV File
if (isset($_POST['submit'])) {
if (is_uploaded_file($_FILES['upload_csv']['tmp_name'])) {
echo "<h1>" . "File ". $_FILES['upload_csv']['name'] ." uploaded successfully." . "</h1>";
}
//Import uploaded file to Database
$handle = fopen($_FILES['upload_csv']['tmp_name'], "r");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$wpdb->insert("my_custom_table", array(
"product_type" => $data[0],
"product_serial" => $data[1],
"created_at" => current_time('mysql', 1)
));
}
fclose($handle);
print "Import done";
}
Print $data output with delimiter ,:
Array
(
[0] => Product Name;product_serial
)
Array
(
[0] => iPhone 6;iphone-002
)
Array
(
[0] => iPhone 6;iphone-003
)
Print $data output with delimiter ;:
Array
(
[0] => Product Name
[1] => product_serial
)
Array
(
[0] => iPhone 6
[1] => iphone-002
)
Array
(
[0] => iPhone 6
[1] => iphone-003
)
Using above, Product Name and product_serial also gets inserted in DB which should be prevented. Also delimiter , does not output correct array while ; does.
How can I prevent CSV column names insertion and insert correct value in Database?
P.S: Using OpenOffice for CSV data insertion. Could formatting be an issue with delimiter ?
The general rule of thumb is the first line of CSV is the column names, therefore a quick skip counter will remove the first row for you:
$counter = 0;
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
// Skip the first row as is likely column names
if ($counter === 0) {
$counter++;
continue;
}
// Insert the row into the database
$wpdb->insert("my_custom_table", array(
"product_type" => $data[0],
"product_serial" => $data[1],
"created_at" => current_time('mysql', 1)
));
}
The other problem is CSV files can have varying column and row delimiters (AKA sometimes columns are sperated by comma, and other times semi colons ...etc) making parsing CSV quite difficult. I this example it seems your column delimiter is semi-colon so modifying your function parameters may fix it for you:
while (($data = fgetcsv($handle, 1000, ";")) !== FALSE) {
If you really must support multiple types of delimiter, the following code snippet may help you:
$csvFilePath = $_FILES['upload_csv']['tmp_name'];
$delimiter = $this->detectDelimiter($csvFilePath);
public function detectDelimiter($csvFile)
{
$delimiters = array(
';' => 0,
',' => 0,
"\t" => 0,
"|" => 0
);
$handle = fopen($csvFile, "r");
$firstLine = fgets($handle);
fclose($handle);
foreach ($delimiters as $delimiter => &$count) {
$count = count(str_getcsv($firstLine, $delimiter));
}
return array_search(max($delimiters), $delimiters);
}

Hope this helps.
i need to upload a .txt file in database.
my .txt file is exactly looks like
Name|Code|Email|Designation|Number|Salary|Age\t
syed|101|syed#gmail.com|trainee|7222877798|6000|21\t
hari|102|hari#gmail.com|trainee|9554512582|6000|23\t
i have need to separate it with | and then \t.
while getting array, the first one achieved as what i expect. but i cant able make \t explode.. can any one help me on this forum??
my routine is described below
if ($_POST['frmSubmit']) {
$file = $_FILES['frmUpload']['tmp_name']; // Get Temporary filename
$handle = fopen($file,"r"); // Open the file and read
while($strBookData = fgets($handle, 4096)) { // To get Array from .txt
$strDatas[] = $strBookData;
$strTableColumn = count($strBookData);
}
$strDatas = explode("|",implode($strDatas));
printArray($strDatas); exit;
if ($strDatas) {
$strInsertRecords = 0;
$strDuplicationRecords = 0;
if ($strTableColumn == 7) {
for($k=1; $k<count($strDatas); $k++) { //$k=1 is initialized because $k[0] is a header field array.
$strStatus = doCheckDuplication($strDatas[$k]['2']);
if ($strStatus == 0) {
// Insert Code
$strData = $strDatas[$k];
doInsertEmployeeDetails($strData['0'], $strData['1'], $strDatas[$k]['2'], $strData['3'], $strData['4'], $strData['5'], $strData['6']);
$strInsertRecords++; // To Get Inserted Records Count.
} else {
$strDuplicationRecords++; // To Get Duplication Records Count.
}
}
}
}
Hi this will split the text you provided.
$text = 'Name|Code|Email|Designation|Number|Salary|Age\t
syed|101|syed#gmail.com|trainee|7222877798|6000|21\t
hari|102|hari#gmail.com|trainee|9554512582|6000|23\t';
//remove line endings
$text = str_replace(array("\r\n", "\r", "\n"), "", $text);
$rows = explode('\t', $text);
$data = array();
foreach ($rows as $row){
//don't include empty lines
if(!empty( $row )){
$data[] = explode('|', $row);
}
}
echo '<pre>';
var_export( $data );
Outputs:
array (
0 =>
array (
0 => 'Name',
1 => 'Code',
2 => 'Email',
3 => 'Designation',
4 => 'Number',
5 => 'Salary',
6 => 'Age',
),
1 =>
array (
0 => 'syed',
1 => '101',
2 => 'syed#gmail.com',
3 => 'trainee',
4 => '7222877798',
5 => '6000',
6 => '21',
),
2 =>
array (
0 => 'hari',
1 => '102',
2 => 'hari#gmail.com',
3 => 'trainee',
4 => '9554512582',
5 => '6000',
6 => '23',
),
);
However that said, there is a lot going on in your example, as for reading the file in. If it's not to large the best bet would be to use file_get_contents() that will read the whole file in one go. Otherwise in this part
$handle = fopen($file,"r"); // Open the file and read
while($strBookData = fgets($handle, 4096)) { // To get Array from
$strDatas[] = $strBookData;
$strTableColumn = count($strBookData);
}
You would be better off just concatenating the text.
$strDatas = '';
$handle = fopen($file,"r"); // Open the file and read
while($strBookData = fgets($handle, 4096)) { // To get Array from
$strDatas .= $strBookData;
}
And then splitting like I did above.
I think that you should first explode using '\t' as delimiter to get the substrings separated by \t (Name|Code|Email|Designation|Number|Salary|Age)
and then explode each substring using '|' as delimiter.
I wish that can help you
I'm trying to parse a CSV string to an array in PHP. The CSV string has the following attributes:
Delimiter: ,
Enclosure: "
New line: \r\n
Example content:
"12345","Computers","Acer","4","Varta","5.93","1","0.04","27-05-2013"
"12346","Computers","Acer","5","Decra","5.94","1","0.04","27-05-2013"
When I try to parse it like this:
$url = "http://www.url-to-feed.com";
$csv = file_get_contents($url);
$data = str_getcsv($csv);
var_dump($data);
The last and first element are concatenated in one string:
[0]=> string(5) "12345"
...
[7]=> string(4) "0.04"
[8]=> string(19) "27-05-2013
"12346""
How can I fix this? Any help would be appreciated.
Do this:
$csvData = file_get_contents($fileName);
$lines = explode(PHP_EOL, $csvData);
$array = array();
foreach ($lines as $line) {
$array[] = str_getcsv($line);
}
print_r($array);
It will give you an output like this:
Array
(
[0] => Array
(
[0] => 12345
[1] => Computers
[2] => Acer
[3] => 4
[4] => Varta
[5] => 5.93
[6] => 1
[7] => 0.04
[8] => 27-05-2013
)
[1] => Array
(
[0] => 12346
[1] => Computers
[2] => Acer
[3] => 5
[4] => Decra
[5] => 5.94
[6] => 1
[7] => 0.04
[8] => 27-05-2013
)
)
I hope this can be of some help.
You should use fgetcsv. Since you cannot import a file as a stream because the csv is a variable, then you should spoof the string as a file by using php://temp or php://memory first:
$fp = fopen("php://temp", 'r+');
fputs($fp, $csvText);
rewind($fp);
Then you will have no problem using fgetcsv:
$csv = [];
while ( ($data = fgetcsv($fp) ) !== FALSE ) {
$csv[] = $data;
}
fclose($fp)
$data will be an array of a single csv line (which may include line breaks or commas, etc), as it should be.
Caveat: The memory limit of php://temp can be controlled by appending /maxmemory:NN, where NN is the maximum amount of data to keep in memory before using a temporary file, in bytes. (the default is 2 MB) http://www.php.net/manual/en/wrappers.php.php
Handy oneliner:
$csv = array_map('str_getcsv', file('data.csv'));
I have used following function to parse csv string to associative array
public function csvToArray($file) {
$rows = array();
$headers = array();
if (file_exists($file) && is_readable($file)) {
$handle = fopen($file, 'r');
while (!feof($handle)) {
$row = fgetcsv($handle, 10240, ',', '"');
if (empty($headers))
$headers = $row;
else if (is_array($row)) {
array_splice($row, count($headers));
$rows[] = array_combine($headers, $row);
}
}
fclose($handle);
} else {
throw new Exception($file . ' doesn`t exist or is not readable.');
}
return $rows;
}
if your csv file name is mycsv.csv then you call this function as:
$dataArray = csvToArray(mycsv.csv);
you can get this script also in http://www.scriptville.in/parse-csv-data-to-array/
A modification of previous answers using array_map.
Blow up the CSV data with multiple lines.
$csv = array_map('str_getcsv', explode("\n", $csvData));
Slightly shorter version, without unnecessary second variable:
$csv = <<<'ENDLIST'
"12345","Computers","Acer","4","Varta","5.93","1","0.04","27-05-2013"
"12346","Computers","Acer","5","Decra","5.94","1","0.04","27-05-2013"
ENDLIST;
$arr = explode("\n", $csv);
foreach ($arr as &$line) {
$line = str_getcsv($line);
}
If you need a name for the csv columns, you can use this method
$example= array_map(function($v) {$column = str_getcsv($v, ";");return array("foo" => $column[0],"bar" => $column[1]);},file('file.csv'));
If you have carriage return/line feeds within columns, str_getcsv will not work.
Try https://github.com/synappnz/php-csv
Use:
include "csv.php";
$csv = new csv(file_get_contents("filename.csv"));
$rows = $csv->rows();
foreach ($rows as $row)
{
// do something with $row
}
You can convert CSV string to Array with this function.
function csv2array(
$csv_string,
$delimiter = ",",
$skip_empty_lines = true,
$trim_fields = true,
$FirstLineTitle = false
) {
$arr = array_map(
function ( $line ) use ( &$result, &$FirstLine, $delimiter, $trim_fields, $FirstLineTitle ) {
if ($FirstLineTitle && !$FirstLine) {
$FirstLine = explode( $delimiter, $result[0] );
}
$lineResult = array_map(
function ( $field ) {
return str_replace( '!!Q!!', '"', utf8_decode( urldecode( $field ) ) );
},
$trim_fields ? array_map( 'trim', explode( $delimiter, $line ) ) : explode( $delimiter, $line )
);
return $FirstLineTitle ? array_combine( $FirstLine, $lineResult ) : $lineResult;
},
($result = preg_split(
$skip_empty_lines ? ( $trim_fields ? '/( *\R)+/s' : '/\R+/s' ) : '/\R/s',
preg_replace_callback(
'/"(.*?)"/s',
function ( $field ) {
return urlencode( utf8_encode( $field[1] ) );
},
$enc = preg_replace( '/(?<!")""/', '!!Q!!', $csv_string )
)
))
);
return $FirstLineTitle ? array_splice($arr, 1) : $arr;
}
Try this, it's working for me:
$delimiter = ",";
$enclosure = '"';
$escape = "\\" ;
$rows = array_filter(explode(PHP_EOL, $content));
$header = NULL;
$data = [];
foreach($rows as $row)
{
$row = str_getcsv ($row, $delimiter, $enclosure , $escape);
if(!$header) {
$header = $row;
} else {
$data[] = array_combine($header, $row);
}
}
