Hay how can I convert
01 to 1
02 to 2
all the way to 9?
Thanks
I assume the input is a string?
$str = "01";
$anInt = intval($str);
You may think that the leading 0 would mean this is interpreted as octal, as in many other languages/APIs. However the second argument to intval is a base. The default value for this is 10. This means 09->9. See the first comment at the intval page, which states that the base deduction you might expect only happens if you pass 0 in as the base.
$str = "05";
$last = $str[1];
$i = substr($input, 1, 1);
$x="01";
$x=+$x;
$x="02";
$x=+$x;
...
or
$x=+"01";
should work for both int, and string
If you want to use the generic regular expression solution: 's/[0]([0-9])/\1/' (add in anchors as appropriate)
$str='05';
if(strpos($str,'0')==0 && strpos($str,'0') != false ){
$new = intval(substr($str,1));
}
Do (int)$str; instead. It's up to 4x faster than intval().
you can use the predefined php function .
intval()
For Ex:
$convert = intval(01);
echo $convert ;
It will print 1(one);
