Normal ASCII data is reading fine with this code in xlsx!
for ($row = 2; $row <= $highestRow; $row++){
$rowData = $sheet->rangeToArray('A'.$row.':'.$highestColumn.$row,NULL,TRUE,TRUE);
}
But not able to read unicode data with this.
Is there any way to read unicode with this from xlsx?
Note : unicode working fine with xls! i am not getting it from xlsx only!

I am using php spreadsheet excel reader to read a excel file and do some manipulation.
It was working fine and suddenly started to return value 'General' in case of integer columns
Sample rows from excel:
Code:
$dataFields = array("alias"=>"alias","store_quantity"=>"store_quantity","godown_quantity"=>"godown_quantity","name"=>"name");
$mandatoryFeilds = array("alias","store_quantity","godown_quantity","name");
$fieldsPos = array();
$data = new Spreadsheet_Excel_Reader();
$data->setOutputEncoding('CP1251');
$data->read($_FILES['upload-file']['tmp_name']);
for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++)
{
if ( isset($data->sheets[0]['cells'][1][$j]) == true )
{
$fieldsPos[$data->sheets[0]['cells'][1][$j]] = $j;
if(array_search($data->sheets[0]['cells'][1][$j],$mandatoryFeilds)!==false)
{
unset($mandatoryFeilds[array_search($data->sheets[0]['cells'][1][$j],$mandatoryFeilds)]);
}
}
}
if(count($mandatoryFeilds)>0)
{
die('Some of the mandatory columns are missing in excel');
}
for ($i = 2; $i <= $data->sheets[0]['numRows']; $i++)
{
//printing the output here to check values received from excel which are some anonymous values getting returned
var_dump($data->sheets[0]['cells'][$i]);
}
Output:
array("alias"=>"General","name"=>"Item A","store_quantity"=>"General","godown_quantity"=>"General")
Can anyone help me on this? Any help will be seriously appreciated
The issue happened because i updated my OS from Ubuntu 14 to Ubuntu 16 which updated the Libre Office version from 4.2 to 5
The excel file in Libre 5 is getting read in above discussed manner. So it has to do with Libre version rather than anything from Spreadsheet reader.
I had the same problems. Turned out that those cells was blocked. That was why Spreadsheet reader couldn't read correctly.
The issue was getting on Libre Office 5 as far as I have checked.
Not getting on Windows when editing the Excel sheet.
I handled the issue by reading the raw field of cellsinfo for integer cases:
$data = new JPhpExcelReader($filename);
$id = $data->sheets[0]['cellsInfo'][$i][1]['raw'];
I'm trying to import a Excel file to my PHP application with PHPExcel but It cannot work correctly with UTF-8 data.
This is my data
Độc quyền
and this is what I retrieve:
Äá»™c quyá»n
This is my code:
$cell = $objWorksheet->getCellByColumnAndRow($col, $row);
$value = $cell->getCalculatedValue();
$arraydata[$row-2][$col]=$value;
Thanks for your help. :)
I am reading an excel spreadsheet with PHP COM utility, everything is working fine except there are some cells in Excel file having different language data. When I read this data through PHP Com it displays like ???????
$ExlApp = new COM ( "Excel.Application" );
$workbook = $ExlApp->Workbooks->Open ( 'f:\dev\htdocs\excel\testfile.xlsx' );
$worksheet = $workbook->worksheets ( 1 );
$done = false;
$row_index = 1;
while ( $done == false ) {
$english = $worksheet->cells ( $row_index, 1 )->value;
$dari = $worksheet->cells ( $row_index, 2 )->value;
if ($english != '') {
$row_index ++;
echo "<div style='float:left;width:420px'>".$english."</div><div>".$dari."</div>";
} else {
$done = true;
}
}
$workbook->close ();
I have checked page encoding and its set to UTF-8. When I open original excel file it shows correct text but when I read it from PHP COM the encoding is lost. Does anyone have solution to this problem.
EDIT
How I can ensure that the value given by excel $worksheet->cells ( $row_index,2)->value is in correct encoding OR is there any property in Excel which I can set through PHP COM so it return data in UTF-8?
I have checked the encoding of value returned by Excel cell through mb_detect_encoding function in PHP and it gives ASCII where as it must give UTF-16 or UTF-8. It appears that excel does not give value in correct encoding.
Here is the Excel file I am reading with this script:
http://asimishaq.com/myfiles/testfile.xlsx
Note that the solution is required using PHP COM-INTEROP only.
As pointed out by #rc we need to specify codepage property in COM constructor to obtain data in correct encoding.
$ExlApp = new COM ( "Excel.Application", NULL, CP_UTF8 );
By changing the above line in script the data is displayed correctly.
I am trying to create a script that can export data from a mysql database containing files (pdf mainly). This data is then imported onto the local version of the system.
However I have a problem with the BLOB field, when I export and import using PHPMYADMIN, it works fine, however when using my script, the BLOB field has additional code added to the top. Almost as if it is code to instruct programs how to deal with it. When i try to import this version into PHPMYADMIN, it doesnt work.
Is is a formatting error, do i need to convert it to a type. At present it is simply pulled from the database as a row['content'] item and then outputted to the csv
Any help would be much appreciated
Regards
///////////////// source code of my script
$file = 'supportingFiles'; // csv name.
$result = mysql_query("SHOW COLUMNS FROM files");
$a = 0;
if (mysql_num_rows($result) > 0) { //print column titles based on number of columns in the two files
while ($row = mysql_fetch_assoc($result)) {
$a++;
}
}
$values = mysql_query("SELECT * FROM files "); //select client details wehere required
while ($rows = mysql_fetch_array($values)) { //print client information
for ($k=0;$k<$a;$k++) {
$csv_output .= $rows[$k].",";

header("Content-type: application/csv");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header( "Content-disposition: filename=supportingFiles.csv");
echo $csv_output; //output data file
when an export is ran using this script the following proceeds the actual content outputted when a csv export of the table is run from phpmyadmin...

that is because CSV is not well standardized as a format (not even the "comma" as in "comma seperated values") and it is because phpmyadmin does some encoding/decoding on the values when exporting/importing.
You need this encoding/decoding part, because your binary BLOB (as you said, mostly PDF) can easily contain commas, line breaks, quotes, and all kinds of stuff that breaks a CSV parser.
To import your files using phpmyadmin, you would have to replicate the encoding machanism used there - lucky you that it's open source and you can have a look at the code.
Alternatively, if you want your own export/import mechanism (lets say: you write your own importer that matches your exporter) then you could make good use of base64 encoding here to ensure your CSV (which is intended as a plain-text format by the way) stores binary data correctly.
exporter:
// convert binary blob to text format
$plaintextdata_for_csv = base64_encode($binarydata_from_blob);
importer:
// decode text format to binary blob
$binarydata_for_blob = base64_decode($plaintextdata_from_csv);
include_once 'mysqlconn.php';
include_once "functions.php";
$filename = $_GET['par'].".xls";
header("Content-type: application/x-msexcel");
header('Content-Disposition: attachment; filename="'.basename($filename).'"');
if ($_GET['i'] == "par1") {
func1();
} else if ($_GET['i'] == "par2") {
echo "şşşıııİİİ";
func2();
} else if ($_GET['i'] == "par3") {
echo "şşşıııİİİ";
func3();
}
this is my export2excel.php file and func1,2,3 are in functions.php file and produces table output all work well except character encoding in a strange way. I am using utf-8 encoding for all my files. 2nd else if statement above produces healthy encoded output but rest 2 are encodes my output with strange characters like "BÃœTÇE İÇİ". it is "BÜTÇE İÇİ" in turkish.
in short. same files, same encoding, same database but different results.
any idea?
Excel uses UTF-16LE + BOM as default Unicode encoding.
So you have to convert your output to UTF-16LE and prepend the UTF-16LE-BOM "\xFF\xFE".
Some further information:

Instead I would use one of the existing libraries
PHP Excel Extension PECL extension by Ilia Alshanetsky (Core PHP Developer & Release Master)
Spreadsheet_Excel_Writer PEAR Package
PHPExcel
Edit:
Some code that could help if you really not want to use an existing library
<?php
$output = <<<EOT
<table>
<tr>
<td>Foo</td>
<td>IñtërnâtiônàlizætiøöäÄn</td>
</tr>
<tr>
<td>Bar</td>
<td>Перевод русского текста в транслит</td>
</tr>
</table>
EOT;
// Convert to UTF-16LE
$output = mb_convert_encoding($output, 'UTF-16LE', 'UTF-8');
// Prepend BOM
$output = "\xFF\xFE" . $output;
header('Pragma: public');
header("Content-type: application/x-msexcel");
header('Content-Disposition: attachment; filename="utf8_bom.xls"');
echo $output;
if anyone is trying to use the excel_writer in moodle and is getting encoding issues with output - say if you're developing a report that has a url as data in a field - then in this instance to simply fix this issue I wrapped the data in quotes so it at least opened up in excel here's my example:
// Moodles using the PEAR excel_writer export
$table->setup();
$ex=new table_excel_export_format($table);
$ex->start_document( {string} );
$ex->start_table( {string} );
// heading on the spreadsheet
$title = array('Report Title'=>'Report 1');
$ex->add_data($title);
// end heading
$ex->output_headers( array_keys($table->columns) );
**foreach($data as $row){
$string="'".trim($row->resname,"'")."'";
$row->resname=$string;
$ex->add_data( $table->get_row_from_keyed($row) );
}**
$ex->finish_table();
$ex->finish_document();
Excel uses UTF-16LE as the default encoding. So you should either convert UTF-8 to UTF-16LE yourself or use one of the tried and tested Excel PHP libs instead of trying to reinvent the wheel. I would recommend using PHPExcel...
