Today we introduce several methods to remove the 0 at the end of the decimal point:

Method 1. Add directly 0

##Because PHP is a weak type, it can directly perform mathematical operations and convert them into numbers.

"; echo '100.01000' + 0 ."
"; echo '100.10000' + 0 ."
"; ?>

Output result:

100 100.01 100.1

Method 2, use floatval() to convert to floating point

"; echo floatval('100.01000')."
"; echo floatval('100.10000')."
"; ?>

Output result:

100 100.01 100.1

Method 3, use rtrim ()Function

"; echo rtrim(rtrim('100.01000', '0'), '.')."
"; echo rtrim(rtrim('100.10000', '0'), '.')."
"; ?>

Output result:

100 100.01 100.1

Method 4. Use regular expression

正则表达式说明： /0+$/ 去掉末尾多余的0 /[.]$/ 去掉末尾的. 943305d0cdc8533a04f5034bb4fe0156"; echo preg_replace('/[.]$/', '', preg_replace('/0+$/', '', '100.1000'))."0c6dc11e160d3b678d68754cc175188a"; echo preg_replace('/[.]$/', '', preg_replace('/0+$/', '', '100.010203000'))."0c6dc11e160d3b678d68754cc175188a"; ?>
