strip first letter

[jeff5656]

I have a variable $x that is "P23456"

 

How do I strip out the P and make it "23456"?

 

thanks.

Is the data consistently in that format?

substr() would do just fine?

[jeff5656]

Well it always starts with either a number or the letter P.  If it's a P I want to strip it.  Sometimes it does not have a P, so if I use substr(), it would remove the first number which is what I dont want.

well check it, it's simple

"well check it, it's simple"

Maybe for YOU it is, but not for me (or I wouldn't be asking in this forum right??).

 

Of course it is simple to the person who knows the answer.  This "truism" does not help ME out very much though does it?

I'm sorry,

 

if(substr($string, 0, 1)=="P"){$string = substring($string, 1, strlen($string));}

 

This should do it

Ok I figured it out.  But instead of being cryptic about it, I will post the solution here so that others can see it in the future:

while ($row=mysql_fetch_assoc($result)){
$string = $row['cpt'];
if ($string[0] == 'P' ){
	$new_cpt = substr($row['cpt'], 1); 
}
else {$new_cpt =$row['cpt'];}
echo $row['cpt']." and new is ".$new_cpt."<br>";
}

Ok your solution is a bit more elegant I'll admit...

[manix]

not really, doesn't matter tho, I hope I helped.

I'm sorry,

 

if(substr($string, 0, 1)=="P"){$string = substring($string, 1, strlen($string));}

 

This should do it

Just a small comment: In the way you're using substr() there (you also put substring() instead of substr()), the third parameter is superfluous. In fact, you'd be trying to take one extract character that doesn't exist from the string.

 

$string = substr($string, 1);

 

Would suffice.

I made a typo, apologies

 

<?php if(substr($string, 0, 1)=="P"){$string = substr($string, 1, strlen($string));} ?>
