[PHP] Concatenate PHP code into a string
Dear List,
How can I include a dynamically generated array:
e.g. for($i=0; $isizeof($cols); $i++)
{ $cols[$i]= mysql_field_name($fields,$i); }
into a MySQL insert query of the type:
$sql= INSERT cols[0],cols[1],cols[2], ..., comment
INTO mytable SET
cols[0]= '$cols[0]',
cols[1]= '$cols[1]',
cols[2]= '$cols[2]',
cols[...]= '$cols[...]',
comment= '$comment';
The number of $cols is different for each table.
Thanks in advance for any help
Alberto Brea

If you have three vars:

$users = array(Peter,Michael);
This could be a problem:
echo $users hair is brown;
if what you ment was:
echo $string.s hair is brown; // Peters hair is brown

RE: [PHP] concatenate vars?
no, you need to do three different comparisons :
if( ... something ... )
(eregi("stuff1", $one) and eregi("stuff2", $two) and eregi("stuff3",
$three)) ? : do this : do that

Thanks,
do you know if making multiple statements to eregi in line 3 is possible?
1. if(...something...)
2.{
3. (eregi("stuff1", $one)("stuff2", $two)("stuff3", $three)) ?
4. do something : do something else;

[PHP] concatenate vars?
I need to combine two variables which are set to two form field values and
will be put into $from of mail(). Should it be $from = "$varOne . $varTwo"
?
also a way to make
if(.something)
(eregi("blah", $one)("blah2", $two)("blah3", $three));will this
work?
