finding a certain space

[Anon]

hi i have a problem with string mainipulation:

$strStr = From: test tester something

i would like to get the integer position of the third space in the string. (after "tester").

has anybody an idea how i can do this ? I tried strpos but this function only gives me ther first occurence of a delimiter in a string.

thanks in advance

do a search for the first space
save that as $first.
Set $str2 = $strStr from $first to the end;
do a search for the first space in $str2
save that as $second.
Set $str3 = $strStr from $second to the end;
do a search for the first space in $str3
save that as $third.
Set $answer = $first +$second+ $third;

It kinda depends on what you know going into it. What is constant? Will it always be the third? or will it always be the space after tester?

Third Sample

<?php
$strStr = "From: test tester something";
for( $loop='0'; $loop=='3'; $loop++) {
$current_position = strpos( $strStr, " ", $current_position);
$current_position++;
}
$current_position--;
echo "The position of the third space is ".$current_position;
?>

tester Sample

<?php
$strStr = "From: test tester something";
$keyword = "tester";
$current_position = strpos( $strStr, $keyword);
$current_position + strlen($keyword);
echo "The position of the third space is ".$current_position;
?>

Hope that helps,
