insert a space into a string IF there isnt a space already

[mackin]

I have a table with postcodes in it. At some point some of the codes will be entered with spaces (LA12 5TH) and some without (LA17HU) what i need is a function to check if there is a space, if not - count back 3 characters from the end of the string and insert a space.

 

I don't know which string function to use - looked at pad but that seems to be for either end of string and not the middle - any ideas?

use wordwrap($str, 3, " ", true) $str being your postalcode 3 being every 3 characters im canadian so this is our standard but it can be changed to any number and it does not leave a traling space ither

thx for the reply blackknight

 

can i use a negative number - the count has to start from the end of string. The Part before the space can be 3 or 4 chars, but always has 3 after the space.??

if (strpos($str, ' ')===false){ //no space
   $str = substr_replace($str, ' ', -3, 0); //insert space
}
