[RESOLVED] string function - not sure which..

[asa_carter]

Which string function do I use to insert a charcater into a string a specific point (not replace a character)?

Thanks

[nemonoman]

[man]substr[/man]
Insert a string at the fifth character

$mybigstring=substr($mylittlestring,0,4).'New text here'.substr($mylittlestr,5);

Or do it all in one function, [man]substr_replace/man:

$string = substr_replace($string, 'New Text', 4, 0);
