I'm use this function time to time and use in the db class.
If somebody may propose change somthing lets disscuse about it.
Code:
<?php
//--[ Function: mod_array2string ]-------------------------------------------------------
#
# @purpose:  Convert array to string or return false or error message if debug mode is active.
#
# @usege:    mod_array2string($arrays [,$delimiter[,$pair]])
# @access:   private
# @usedef:   boolean  MOD_AUTOPAIR           if on and even pair put auto comma ", "
# @usedef:   boolean  MOD_DEBUG              debug mode output error message if they exists
# @param:    string   $arrays                table arrays
# @param:    string   $delimiter             delimiter betwen elements default is comma ", "
# @param:    string   $pair                  set special delimiter between values as 1=2,3=4,etc.
# @param:    string   $keys                  try save array structure as key = value
# @param:    return   $return_values         return parsed result or return invoked string
#

/*
Example 1:
DEFINE ('MOD_AUTOPAIR','on');
$dd = array("q","w","e","r");
echo mod_array2string($dd," = ");

out: q = w, e = r
-------------------------------------------------------
Example 2:
DEFINE ('MOD_AUTOPAIR','off');
$dd = array("q","w","e","r");
echo mod_array2string($dd," = ");

out: q = w = e = r
-------------------------------------------------------
Example 3:
$dd = array("q"=>8,"w"=>"fgh","e"=>71,"r"=>'SsA');
echo mod_array2string($dd," = ",", ",keys);

out: q = 8, w = fgh ,e = 71, r = SsA
-------------------------------------------------------
Example 4:
$dd = array("q"=>8,"w"=>"fgh","e"=>71,"r"=>'SsA');
echo mod_array2string($dd," = ",", ",true,"`");

out: `q` = `8`, `w` = `fgh`, `e` = `71`, `r` = `SsA`

looks pretty good..however description of the last function is totaly from the previous function ^^
ouch!
Danke!
 
What's wrong with serialize(), unserialize() functions???
 
Previous post was posted 17 years ago, in that time OP could know somebody, get married, have a child and the child could growth enough to be know that no one should reply to old threads such like this one
