The problem is that there is no space between the numbers. How do I add this space


Change echo $i + ""; to echo $i . " ";

I have this PHP code that displays values in an array:
$header->from[0]->mailbox . "#" . $header->from[0]->host;
whats the best way to loop round to get [1], [2], [3], etc...

You can do it through a foreach loop like this:
foreach ($header->from as $from){
echo $from->mailbox . "#" . $from->host;
}
If you want to process the first element outside the loop, then you can use array_shift:
$first_from = array_shift($header->from);
$first_from->mailbox . "#" . $first_from->host;
foreach ($header->from as $from){
echo $from->mailbox . "#" . $from->host;
}

Why can't I call this function with the function and increment it's argument?
It seems to loop endlessly without $i incrementing.
function loopy($i) {
loopy($i+1);
echo $i.'...';
if ($i >=5) return true;
}

Because the if statement needs to go before calling the function again to stop it beign an infinite loop:
function loopy($i) {
if ($i >=5) return true;
loopy($i+1);
echo $i.'...';
}

I want to see if the last two characters/digits in a filename are numbers in PHP.
if (CODE HERE) {
// runs script because last two characters are numbers
}
This should set it off:
http://www.nws.noaa.gov/weather/images/fcicons/hi_shwrs20.jpg
The last two digits are '20'
This should not:
http://www.nws.noaa.gov/weather/images/fcicons/skc.jpg
There are no last two digits

This should do the trick.
<?php
$filename = "http://www.nws.noaa.gov/weather/images/fcicons/skc23.jpg";
$posOfPeriod = strrpos($filename, ".");
$last2digits = substr($filename, $posOfPeriod -2, 2);
if (is_numeric($last2digits)) {
echo "Numeric: ".$last2digits;
}
else {
echo "Non-Numeric: ".$last2digits;
}
?>

$a='Would you like to have responses to your questions sent to you via email'
for($a as $b=>c){
}
Kindly give me the solution

<?php echo substr_count($a, 't'); ?>

Here's a solution, though not necessarily the best
$letterCount = array_count_values(
str_split(strtolower($a))
);
$tCount = (isset($letterCount['t'])) ? $letterCount['t'] : 0;

$count = preg_match_all('/t/', $str);

check this one
<?php
$a = 'Would you like to have responses to your questions sent to you via email';
$t_explod = explode('t', strtolower($a));
echo count($t_explod) - 1;
?>
