PHP thousand separator formatting for generated page from xlsx - php

Question

Ty mail2bapi, :)
Im using SimpleXLSX and example script below in code i added this $x = number_format($r);
Just need the numbers to have thousand separator
252252732
to
252,252,732
IM not good with PHP, really appreciate any help
Plus some columns are empty and dates like so 23.01.2020, I think this is what is causing the issue
XMLS File
simplexlsx
Error: number_format() expects parameter 1 to be double, array given in
Error: implode(): Invalid arguments passed
<?php
require_once 'SimpleXLSX.php';
if ( $xlsx = SimpleXLSX::parse('book.xlsx') ) {
echo '<table border="1" cellpadding="3" style="border-collapse: collapse">';
foreach( $xlsx->rows() as $r ) {
$x = number_format($r);
echo '<tr><td>'.implode('</td><td>', $x ).'</td></tr>';
}
echo '</table>';
// or $xlsx->toHTML();
} else {
echo SimpleXLSX::parseError();
}
?>

You are not using number_format() function correctly. Change following code from -
$x = number_format($r);
to
$x = number_format($r, 0, ".", ",");
for more information visit PHP number_format
EDIT
As you mentioned your row could have a different type of values, it is better to check the value for numeric.
Try this code
<?php
require_once 'SimpleXLSX.php';
if ( $xlsx = SimpleXLSX::parse('book.xlsx') ) {
echo '<table border="1" cellpadding="3" style="border-collapse: collapse">';
foreach( $xlsx->rows() as $rowValue ) {
echo "<tr>";
// As $rowValue is an array
foreach($rowValue as $value){
// Check for number_format
if(is_numeric($value)){
$x = number_format($value, 0, ".", ",");
echo "<td>".$x."</td>";
}else{
echo "<td>".$value."</td>";
}
}
echo "</tr>";
}
echo "</table>";
// or $xlsx->toHTML();
} else {
echo SimpleXLSX::parseError();
}
Hope these resolve your issue.
