[leon77]

hello everyone

anyone know why the first foreach statement
will not produce "12345678910"

im trying to imput my ranges
as variables

any help greatly appreciated thanks, .:leon:.

$range1 = "1";
$endRange1 = "10";

foreach(range($range1, $endRange1) as $number) {
echo $number; / this echo's "1" /
}

$range1 = "1";
$endRange1 = "10";

foreach(range(1, $endRange1) as $number) {
echo $number; / this echo's "12345678910" /
}

Hi
Interesting issue
I check your code on my server - the same
then I checked php manual - they don't use variables to input range function

then I do the following
first I remove "" in $range1 and $endRange variables definition - no result
then I tried to use 10 instead of $endRange1 - works

then I copy $endRange1 from varibale definition string and it start working

<?
$range1 = 1; 
$endRange1 = 10; 

foreach(range($range1, $endRange1) as $number) { 
echo $number; /* this echo's "1" */ 
} 
print "\n";

$range1 = "1"; 
$endRange1 = "10"; 

foreach(range(1, $endRange1) as $number) { 
echo $number; /* this echo's "12345678910" */ 
}
?>

and it start working
I don't know why:-)

you shouldnt use a foreach statement to do counting like this.

try/.

<?php
for ($i = 0; $i <= 10; $i++) {
print "we are currently on number #$i<br>\n";
}
?>

here is how a foreach should be used.

<?php
$numbers=Array("0","1","2","3","4","5","6","7","8","9");
foreach($numbers as $num){
print "we are currently on number #$num<br>\n";
}
?>

hope that helps/

i figured out why it worked for you,

when you defined you variables on the first set, you left off
the quotes. this must tell the range() that they are true int's.

works now,
cool,
thanks vvlad
