10x !!!!

On my server work only -> $zip = new ZipArchive;

But all another is great !!!

Thanks for sharing. I like this approach as it 1) is light and 2) allows better control.

In my particular case where I was implementing it, I had issues due to blank/null cells so my values didn't always fall under the correct header. I was able to solve it with the following pieces of code:

  1. Identify (or count) each row by adding this line just before the first foreach:
$row_cnt = 1; 

Update it with this code as the last line of the same foreach loop:

$row_cnt++;
  1. Create a key for each column by adding this code as the first line of the second foreach:
$cellid = preg_replace('/[^A-Z]/i', '', $cell['r']);

This adds a column reference to be used as a key for each array member (for example: 'A', 'B', 'C', etc) The preg_replace simply removes the row reference ('A1' becomes 'A').

  1. To assign the key created in step 2 to each cell, change the line
  $arr[] = $v;

to

 $arr[(string)$cellid] = $v;
  1. Change the 'else' statement to:
 } else {
 // Combine the row with the headers
 foreach ($headers as $arrkey => $title) {
    //assign header name as key and add missing cells
    $row[$row_cnt][$title] = $arr[$arrkey];
 }

That should do it. Each row of the first array will have the row number as its key. And each column array will contain all header titles as keys even if the original cell was blank/null.

Also, to see your headers, use this code at the end of the function:

echo '<ol>';
  foreach ($headers as $arrkey => $xlrows) {
      echo '<li>'.$arrkey.' = '.$xlrows.'</li>';
 }
echo '</ol>';

Or to see your finished array, use this:

echo '</ol>';
foreach ($row as $arrkey => $xlrows) {
    echo '<h4>Row '.$arrkey .'</h4><ol type="A">';
    foreach ($xlrows as $key => $cell) {
        echo '<li>'.$key.' = '.$cell.'</li>';
    }
echo '</ol>';

Maybe this will help someone.

This is most helpful. Thank you.

Personally, I wanted to see the columns in an array for each row -- small adjustment:

            $arr = array()
            $row = 0;
            foreach ($xlrows as $xlrow) {

                // In each row, grab it's value
                foreach ($xlrow->c as $cell) {
                    $v = (string) $cell->v;

                    // If it has a "t" (type?) of "s" (string?), use the value to look up string value
                    if (isset($cell['t']) && $cell['t'] == 's') {
                        $s  = array();
                        $si = $strings->si[(int) $v];

                        // Register & alias the default namespace or you'll get empty results in the xpath query
                        $si->registerXPathNamespace('n', 'http://schemas.openxmlformats.org/spreadsheetml/2006/main');

                        // Cat together all of the 't' (text?) node values
                        foreach($si->xpath('.//n:t') as $t) {

                            $s[] = (string) $t;

                        }
                       $v = implode($s);

                    }

                    $arr[$row][] = $v;

                }

                    $row++;
              }

I use this script and it worked properly!, but I have a problem with dates, for example if I have a date 20/12/2012 in the xlsx document, worksheet 41263 write me, and I did not realize that conversion does.

anyone have any idea how I can fix this.

Hi.
Thanks for the great script.
Sometimes when there are empty cells they are missing in the xml which makes the script misplace the cell.
Example:
<row r="1" spans="1:12" x14ac:dyDescent="0.2"> <c r="A1" s="4" t="s"> <v>179</v> </c> <c r="B1" s="4" t="s"> <v>4568</v> </c> <c r="C1" s="4" t="s"> <v>180</v> </c> <c r="D1" s="4" t="s"> <v>181</v> </c> <c r="E1" s="6" t="s"> <v>5</v> </c> <c r="F1" s="6" t="s"> <v>6</v> </c> <c r="G1" s="6" t="s"> <v>7</v> </c> <c r="H1" s="6" t="s"> <v>8</v> </c> <c r="I1" s="6" t="s"> <v>4565</v> </c> <c r="J1" s="6" t="s"> <v>4566</v> </c> <c r="K1" s="7" t="s"> <v>4567</v> </c> <c r="L1" s="6" t="s"> <v>4569</v> </c> </row> <row r="2" spans="1:12" x14ac:dyDescent="0.2"> <c r="A2" s="7"> <v>1</v> </c> <c r="C2" s="7"> <v>1</v> </c> <c r="D2" s="7" t="s"> <v>13</v> </c> <c r="E2" s="8"/> <c r="F2" s="8"/> <c r="G2" s="8"/> <c r="H2" s="8"/> <c r="J2" s="6" t="s"> <v>104</v> </c> <c r="K2" s="6"/> </row> <row r="3" spans="1:12" x14ac:dyDescent="0.2"> <c r="A3" s="7"> <v>2</v> </c> <c r="C3" s="7"> <v>0</v> </c> <c r="D3" s="7" t="s"> <v>182</v> </c> <c r="E3" s="6" t="s"> <v>104</v> </c> <c r="F3" s="6" t="s"> <v>104</v> </c> <c r="G3" s="8"/> <c r="H3" s="6" t="s"> <v>104</v> </c> <c r="I3" s="6" t="s"> <v>104</v> </c> <c r="J3" s="6" t="s"> <v>104</v> </c> <c r="K3" s="6" t="s"> <v>104</v> </c> </row>

The first row are the headers. All the cells are present there. The second row is missing B, I and L cells. L is filled with "" by the script, but everything after B is misplaced by one cell and after I by two. The third row is missing is missing B & L - again everything after B in moved one up and the "$values = array_pad($arr, count($headers), '');" is filling the wholes at the end.
I've made a small fix which suits my needs, but it will work only up to 26 columns. Maybe you can think of something else.
Fix:
`// In each row, grab it's value
$alphabet = range('A', 'Z');//set the alphabet in array//Put this one outside the first loop
$ic = 0;
foreach ($xlrow->c as $cell) {
$cellLetter = trim(str_replace(range(0, 9), '', $cell['r']));//removing the numeric from R
if ($cellLetter != $alphabet[$ic]) {//cell is missing between this one and the last proccesed
$arr[] = '';//fill with empty
$ic++;
}
$v = (string)$cell->v;

            // If it has a "t" (type?) of "s" (string?), use the value to look up string value
            if (isset($cell['t']) && $cell['t'] == 's') {
                $s = array();
                $si = $strings->si[(int)$v];

                // Register & alias the default namespace or you'll get empty results in the xpath query
                $si->registerXPathNamespace('n', 'http://schemas.openxmlformats.org/spreadsheetml/2006/main');
                // Cat together all of the 't' (text?) node values
                foreach ($si->xpath('.//n:t') as $t) {
                    $s[] = (string)$t;
                }
                $v = implode($s);
            }

            $arr[] = $v;
            $ic++;
        }`

Dates in excel are numbers representing the number of days since 01.01.1900.
Thus 41263 in a date cell is something like 113 years and 18 days since 01.01.1900 = 18.01.2013.

Here are two PHP functions to convert Excel dates into days, months, years:

    // EXCEL serialDATE conversions based on Julian <-> Gregorian calendars
    protected static function excel_D2DMY($days) {
        if ($days < 1){
            return '';
        }
        if ($days == 60)  {
            return array('day'=>29, 'month'=>2, 'year'=>1900);
        } else {
            if ($days < 60)  {
                // Because of the 29-02-1900 bug, any serial date
                // under 60 is one off... Compensate.
                ++$days;
            }
            // Modified Julian to DMY calculation with an addition of 2415019
            $l = $days + 68569 + 2415019;
            $n = floor(( 4 * $l ) / 146097);
            $l = $l - floor(( 146097 * $n + 3 ) / 4);
            $i = floor(( 4000 * ( $l + 1 ) ) / 1461001);
            $l = $l - floor(( 1461 * $i ) / 4) + 31;
            $j = floor(( 80 * $l ) / 2447);
            $nDay = $l - floor(( 2447 * $j ) / 80);
            $l = floor($j / 11);
            $nMonth = $j + 2 - ( 12 * $l );
            $nYear = 100 * ( $n - 49 ) + $i + $l;
            $ret = array('day'=>$nDay, 'month'=>$nMonth, 'year'=>$nYear);
            return $ret;
        }
    }

nice work! On my version of PHP the $headers = array(); in the beginning is necessary. would be a tiny update to this. I suggest allowing pull requests.
