PHP Question

How to remove first whitespace of string

He there,

I am building a new version of an telephone configuration manager where I am sucking on a stupid problem. You see this telephone .cfg configurations are rely static. So in the old version I made it gave the conf without problem.

It looks like this:

##configuration header
configuration_1="parram"
configuration_2="parram"
configuration_3="parram"


etc.

Now in the new version the configuration is given as this:

whitespace
##configuration header
configuration_1="parram"
configuration_2="parram"
configuration_3="parram"


note that white space is actually white space and that the phone does not take the configuration because it wants to see the first line have the #header.

So I figured that the easy way to fix this is to just backspace the first white line but how. How can i tell php to delete the first line?

Ok look this: image

The first to screenshots are form phpmyadmin where you see that inside an textarea there is no white space but when just echoing it out you suddenly see it. The strange thing is that when Manuel changing the config with phpmyadmin it is removed somehow but it has be done automatic.

If you have the contents as a string, just run ltrim.
It will strip away all the whitespaces from the starting of the string.

$str = ltrim($str);
