fopen write with variable issue - php

Question

small project - stumped typing to get it working - if you have any ideas please let me know tku! This post program is requiring more words so here we go
<?php
$row = 1;
if (($handle = fopen("issue-heads-1.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle)) !== FALSE) {
if ($row == 2) {
$file = fopen($data[14], "w");
$write = '
<?php
include "/home/history/public_html/issue1.php";
echo \'<a class="prev" href="\' . $data[16] . \'">\';
?>
';
fwrite($file, $write);
fclose($file);
}
$num = count($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);
}
?>

Answer 1

Quick guess - Try (untested):
$write = '
<?php
include "/home/history/public_html/issue1.php";
echo \'<a class="prev" href="' . $data[16] . '">\';
?>
';
It's just a bit tricky with the multiple quotes... think you might have lost track of which ones need escaping...
Hmmmm... so that didn't work... the next thing I would try is to construct the $write variable over several lines (hopefully making the job a bit easier, so perhaps easier to avoid error) - note that I also threw in a repeating filewrite to see what the output is:
$hF = fopen('__debug.log', "a"); //outside your loop
//inside loop
$hrf = $data[16];
$write = '<?php' + "\n";
$write .= 'include "/home/history/public_html/issue1.php";' + "\n";
$write .= "echo '<a class=\"prev\" href=\"";
$write .= $hrf;
$write .= "\">';" + "\n";
$write .= '?>';
fwrite($hF, $write);
and make sure to close the file before your script ends:
//outside the loop
fclose($hF);

Answer 2

Using a variable inside a write statement didn't work while inside a fopen statement. I ended up having to use ob_start to get it to work. Hat tip to gibberish for getting me on the right path.
<?php
ob_start();
include 'issue1.php';
$issueone = ob_get_contents();
ob_end_clean();
$row = 1;
if (($handle = fopen("issue-heads-1.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle)) !== FALSE) {
$csv[] = $data;
}
fclose($handle);
}
$file = fopen($csv[$row][14], "w") or die("Unable to open file!");
fwrite($file, $issueone);
fwrite($file, "<a class=\"prev\" href=\"" . $csv[$row][16] . "\">");
fclose($file);
print "ok";
?>

If you have unique headers in your CSV
$headers = [];
while (false !== ($data = fgetcsv($handle))) {
if(empty($headers)){
$headers = $data; //["foo", "bar"] (for example)
continue; //skip to next iteration
}
//$data [1,2] (for example)
$row = array_combine($headers, $data);
//$row = ["foo"=>1,"bar"=>2] (for example)
}
Now you can use the text headers instead of 16 etc...
One thing to be careful of is array combine is very sensitive to the length of the arrays. That said if it errors you either have duplicate keys (array keys are unique) or you have either an extra , or a missing one for that line.
Array combine takes the first argument as the keys, and the second as the values and combines them into an associative array. This has the added benefit that the order of your CSV columns will not be important (which can be a big deal).
PS as I have no idea what your headers are, I will leave that part up to you. But lets say #16 is issues. Now you can simply do $row['issues'] just like a DB source etc...
Cheers.
