quick question

Hi,

 

i've got a string which begins with a ".", how can I get rid of it?

 

e.g. $str = ".hello", I want $str = "hello"

 

thanks!

<?php

$str = ".hello";
$clean_str = ereg_replace(".", "", $str);

echo $clean_str;

?>

hmm I tried your code but nothing got printed :S

 

I only want to remove the first ".", if there are subsequent "." I want to keep them..

ok:

 

i think this might work......I dont know about php, but it would in python.  I dont know about the string indexing etc in php or even if it supports it, however :

 

 

$char = string[0];

if ($char == ".") {

      $new_string = string[1:-1];

}

 

print $new_string

 

 

ive put python code in blue....

 

 

hope this helps

I know how to do the string[0] bit in PHP, its just $str[0].

 

$str[1:-1] unfortunately doesn't work..

I can't tell you how, but it can probably be done with preg_replace().

$str= str_replace(".", "", ".hello");

If the "." in the beginning is going to be there every time, you can simply take substring of the given string.

 

<?
$str="Test";

if($str[0] == ".")
{
    $str = substr($str,1);
}

?>

 

I think this shall solve the problem.
