[RESOLVED] Left & Right

[onh1986]

Hello
I set a string "abcdefg".
How can I return a string containing a specified number of characters from the left or right side of the string I set?

Example:
If I want to return 3 characters from the left of the string above, it'll print "abc".

In VB6, I can do that by "Left$(str,Length)" or "Right$(str,Length)".

Thanks

Use the SubStr function.

Check out the exmples below.

echo substr('abcdef', 1);    // bcdef
echo substr('abcdef', 1, 3);  // bcd
echo substr('abcdef', 0, 4);  // abcd
echo substr('abcdef', 0, 8);  // abcdef
echo substr('abcdef', -1, 1); // f
