replace characters in string until different character

Question

OK lets assume I have

   $value = '0.0005304';

I'm struggling to work out how I can remove all instances of 0 until another character is detected. So in the case above the end result would be 5304

I know I should show code working out however I'm unsure on how to do this so don't know where to start looking.

Any help would be appreciated

** Added ** The 2 numbers are stock market prices , open & close basically I want to deduct the open from the close

this value will be the difference between the 2 example open = 1.23456 close = 1.23446 is a difference of -0.00010 I would want this represented as -10 points

Hope this explains more

All instances of 0 until another character would be .0005304 — apokryfos

Try the following:

$value = '0.0005304';

$value = (int)str_replace('.','', $value);

var_dump($value); //output 5304

str_replace will remove the . and (int) will cast it to int which will remove all the 0s

Trim off the zeroes, or in your case, the zeroes and the decimal.

$value = ltrim($value, '0.');

I don't know if referring to this as "replace characters" is accurate, though. It seems we're replacing them with nothing.

I hate that this works lol. 3v4l.org/11V8A Can you explain why the other 0's get trimmed even tho you're only telling it to trim 0.?

This is a much better solution. Even though OP did not specify, this will work for 3.00052 or the like, whereas the other answer won't.

@WillParky93 The second argument is a character mask. It will trim any included characters. For '0.' It trims 0 and ..
