Please see str_pad, as this already does what you're looking for: http://php.net/str-pad Example code: for ($i=1;$i<=101;$i++) { // This gives 'foo0001' print "foo" . str_pad($i, 4, "0", STR_PAD_LEFT) . "\n"; } Previous Comments: ------------------------------------------------------------------------ [2005-06-17 02:26:17] tiago dot freire at gmail dot com Description: ------------ Suppose I want to build a string with fixed length (for whatever reason) by appending a number to a string. //I want strings like 'foo0001','foo0002','foo0010' etc for ($i=1;$i<1000;$i++) { $string = 'foo'.$i; } strval could be useful IF it accepted a second (int) parameter to tell it: "This number will have <int parameter> characters in string form,fill it to the left with zeroes" With this behaviour,this would work: for ($i=1;$i<1000;$i++) { $string = 'foo'.strval($i,4);//This would give me '0001' } What about floats? Another parameter. Explained by example: for ($i=1;$i<1000;$i++) { $string = 'foo'.strval($i,4,3);//This would give me '0001.000' } For completeness: $number = 123456789; $string = 'bignumber: '.strval($number,5); Will result in the string 'bignumber123456789', since I asked for less characters than the number has. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33374&edit=1
