Notice: Uninitialized string offset: 3 in /var/www/ajax/check_name.php on line 67 Notice: Uninitialized string offset: -1 in /var/www/ajax/check_name.php on line 73

Lines 66-76:

for($i = 0; $i < strlen($name); $i++)
	if($name[$i] == $name[($i+1)] && $name[$i] == $name[($i+2)])
	{
		echo '<font color="red">Name can\'t contain 3 same letters one by one.</font><br /><font color="green"><u>Good:</u> M<b>oo</b>nster</font><font color="red"><br />Wrong: M<b>ooo</b>nster</font>';
		exit;
	}
for($i = 0; $i < strlen($name); $i++)
	if($name[$i-1] == ' ' && $name[$i+1] == ' ')
	{
		echo '<font color="red">Use normal name format.</font><br /><font color="green"><u>Good:</u> <b>Gesior</b></font><font color="red"><br />Wrong: <b>G e s ior</b></font>';
		exit;

Everything works fine, but theres an error. I tried to hide this by adding ^ E_NOTICE in error reporting, but it doesn't work. And i have no idea whats wrong with that.

It should be ~E_NOTICE

Is this line 73?

if($name[$i-1] == ' ' && $name[$i+1] == ' ')

If so try this:

if($i >= 1 && $name[$i-1] == ' ' && $name[$i+1] == ' ')

Edit:
Adjusted the title.

It work. But still error in 67 line.

Notice: Uninitialized string offset: 4 in /var/www/ajax/check_name.php on line 67

if($name[$i] == $name[($i+1)] && $name[$i] == $name[($i+2)])

php.net manual:

// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);

But i tried even: "error_reporting(0);" ...

Try adding the error reporting into index.php just below <?PHP

error_reporting( E_ALL ); 
ini_set( 'display_errors', 1 );

Just put 0 to disable it.

Changed display_errors in php.ini and error is gone.
I really don't wanted to change it and restart apache every time when i want to check errors. But if everyone say its best way, so i will stay with it.
Anyway, thanks for help.
