PHP Array to CSV
csv, php
Solution
Instead of writing out values consider using `fputcsv()`.
This may solve your problem immediately.
Note from comment: I should mention that this will be making a file on your server, so you'll need to read that file's contents before outputting it, also if you don't want to save a copy then you'll need to ùnlink`the file when you are done
Problem
I'm trying to convert an array of products into a CSV file, but it doesn't seem to be going to plan. The CSV file is one long line, here is my code: ``` for($i=0;$i<count($prods);$i++) { $sql = "SELECT * FROM products WHERE id = '".$prods[$i]."'"; $result = $mysqli->query($sql); $info = $result->fetch_array(); } $header = ''; for($i=0;$i<count($info);$i++) { $row = $info[$i]; $line = ''; for($b=0;$b<count($row);$b++) { $value = $row[$b]; if ( ( !isset( $value ) ) || ( $value == "" ) ) { $value = "\t"; } else { $value = str_replace( '"' , '""' , $value ); $value = '"' . $value . '"' . "\t"; } $line .= $value; } $data .= trim( $line ) . "\n"; } $data = str_replace( "\r" , "" , $data ); if ( $data == "" ) { $data = "\n(0) Records Found!\n"; } header("Content-type: application/octet-stream"); header("Content-Disposition: attachment; filename=your_desired_name.xls"); header("Pragma: no-cache"); header("Expires: 0"); array_to_CSV($data); function array_to_CSV($data) { $outstream = fopen("php://output", 'r+'); fputcsv($outstream, $data, ',', '"'); rewind($outstream); $csv = fgets($outstream); fclose($outstream); return $csv; } ``` Also, the header doesn't force a download. I've been copy and pasting the output and saving as .csv EDIT PROBLEM RESOLVED: If anyone else was looking for the same thing, found a better way of doing it: ``` $num = 0; $sql = "SELECT id, name, description FROM products"; if($result = $mysqli->query($sql)) { while($p = $result->fetch_array()) { $prod[$num]['id'] = $p['id']; $prod[$num]['name'] = $p['name']; $prod[$num]['description'] = $p['description']; $num++; } } $output = fopen("php://output",'w') or die("Can't open php://output"); header("Content-Type:application/csv"); header("Content-Disposition:attachment;filename=pressurecsv.csv"); fputcsv($output, array('id','name','description')); foreach($prod as $product) { fputcsv($output, $product); } fclose($output) or die("Can't close php://output"); ```
