Er, you are aware that you can reference strings as arrays in PHP, or if
needed convert a string to a real array in one line, right?
for ($i=0; $i < strlen($string); ++$i) {
print $string[$i] . "\n";
}
foreach (explode($string) as $char) {
print $char . "\n";
}
How do you tell PHP what the list delimiter is?
Actually Christopher mixed up the argument order for explode()[1]. It's:
explode("delimiter", $string);
Actually, explode isn't even the right function to use for what he's
demonstrating. The str_split function[2] is actually what you want.
foreach(str_split($string) as $char) {
print $char . "\n";
}

[2] http://us3.php.net/manual/en/function.str-split.php
<cfset str = "a,b,c,d|d,e,f,g*h,i,j,k|l,m,n,o">
I can then turn around and get the first element based on the asterisk
being the delimiter and then treat the result (a,b,c,d|d,e,f,g) as a new
list who's delimiter is the pipe and then end up with last list whose
delimiter is the comma.
<cfloop index="i" from ="1" to="#ListLen(str, '*')#">
<cfset str2 = ListGetAt(str, i, "*")>
<cfloop index="n" from="1" to="#ListLen(str2, '|')#">
<cfset str3 = ListGetAt(str2, n, "*")>
<cfloop index="j" from="1" to="#ListLen(str3)#">
<!--- do some stuff with the innermost elements of the
list --->
</cfloop>
</cfloop>
</cfloop>
Can you do that in php?
$str = "a,b,c,d|d,e,f,g*h,i,j,k|l,m,n,o";
foreach(explode("*", $str) as $half) {
foreach(explode("|", $half) as $quarter) {
foreach(explode(",", $quarter) as $letter) {
// Do something unbelivably cool
}
}
}
