note 74191 added to function.substr

I made a function that removes the last zero's in a string or integer. <?php function removeDotZero($var) { $var = trim($var); $pos = strpos($var,"."); if($pos != false) { $size = strlen($var); for($i = $size; $i > $pos; $i--) { if(substr($var,-1,1) == "0") $var = substr($var,0,($i - 1)); else if(substr($var,-1,1) == ".") { $var = substr($var,0,($i - 1)); break; } else break; } return $var; } else return $var; } echo removeDotZero("100.0052520")."\n"; echo removeDotZero("100.0000000")."\n"; ?> // produces: // 100.005252 // 100 ---- Server IP: 83.137.20.120 Probable Submitter: 80.61.120.39 ---- Manual Page -- http://www.php.net/manual/en/function.substr.php Edit -- https://master.php.net/note/edit/74191 Del: integrated -- https://master.php.net/note/delete/74191/integrated Del: useless -- https://master.php.net/note/delete/74191/useless Del: bad code -- https://master.php.net/note/delete/74191/bad+code Del: spam -- https://master.php.net/note/delete/74191/spam Del: non-english -- https://master.php.net/note/delete/74191/non-english Del: in docs -- https://master.php.net/note/delete/74191/in+docs Del: other reasons-- https://master.php.net/note/delete/74191 Reject -- https://master.php.net/note/reject/74191 Search -- https://master.php.net/manage/user-notes.php
