PHP format number to omit trailing zeros [duplicate] - php

Question

php - add comma thousands separator but remove trailing zeros
(4 answers)
Closed 5 years ago.
A while ago I wrote a fully working script to magically move the decimal sign, adapted to the number of zeros there are.
https://github.com/jenstornell/magic-number-format/blob/master/magic-number-format.php
I still wonder, is there a PHP function to cover this issue? I feel like my code is just too much:
<?php
function magic_number_format($number) {
$pos = strpos($number, '.');
$pos = ( ! $pos ) ? strpos($number, ',') : $pos;
if( $pos ) {
$count = strlen($number) - $pos - 1;
$last = substr($number, -$count);
$split = str_split($last);
$split = array_reverse($split);
$break = false;
foreach( $split as $char ) {
if( $char == 0 && $break == false ) {
$count--;
}
if( $char != 0 ) {
$break = true;
}
}
$first = number_format( substr($number, 0, $pos ), 0, '', '.' );
$last = substr($number, $pos + 1, $count);
$result = $first . ',' . $last;
$result = ( ! is_numeric( substr($result, -1) ) ) ? substr($result, 0, -1) : $result;
return $result . "\n";
}
return number_format( $number, 0, '', '.' ) . "\n";
}
echo magic_number_format('25');
echo magic_number_format('123.32');
echo magic_number_format('12312.3233');
echo magic_number_format('12.0100000');
echo magic_number_format('1231,00');
echo magic_number_format('1231,10');
echo magic_number_format('1,1');
The code above will skip the unneeded zeros after the comma or dot sign.

You are reinventing the wheel. Also the code in answer linked as duplicate is not necessary neither the only approach nor the best approach (it also is not necessary fully related to your question). You can successfully stick using plain printf() with ordinary %s formatting for expected results. Test case:
$vals = [ 1, 1.000, 1.1, 1.230 ];
foreach ($vals as $val) {
printf("%s\n", $val);
}
would produce desired:
1
1
1.1
1.23
Replace printf) with sprintf() if you need to assing formatted value to a variable and you are good to go.
