Dropping words from a string in php

i have a string

showing 1 - 12 of 324 Results

i want to stip this string like

324 Results

or

324

only

Note that, 324 is figure that will change every time the string is obtained. it may be 2-figures (34), three or 4 figured.

currently i am at success only in droping showing word using code

'str_replace('Showing', '', $s)'

this gives out put as

1 - 12 of 324 Results

how can i use str_replace function to get my purpose? or i should use anyother function of PHP?

$results = explode('of', $str);
$results = (int)$results[1];

Use This So easy

$exampleString = "showing 1 - 12 of 324 Results";
$arrayResult   =explode(" ",$exampleString);

//output will be 324,according to the index the result will change
echo $arrayResult[5];

check this : 

$result = "showing 1 - 12 of 324 Results";
$buffer = substr( $result , strpos( $result , "of") + 2 , strlen($result));
//$buffer is : 324 Results

$buffer = explode(" ", $buffer);

// you have to block 1 : $buffer[0] ~ '324' AND 2 : $buffer[1] : 'result'

Alex's answer is good, maybe a regular expression needs more time to understand. You can explode the string and just get the element before the last one.

$arr = explode(' ', 'showing 1 - 12 of 324 Results');
$number = $arr[count($arr)-2];

This way you will get the number of total results. And whenever you want you can add the 'Results' word. Don't forget to trim() the string before the explode() is called.

One solution would be to split the strings at " of " and again at " Results". 

$temp = explode(' of ', $yourString);
$temp2 = explode(' Results', $temp[1]);
$totalResults = $temp2[0];

You can also use preg_match() as alex suggested, which is a more 'elegant' solution as it is done with one function call but may be difficult to understand if you are not familiar with regex.

This should work:

preg_replace('~^.*?(\d+\s+Results)$~i', '$1', 'showing 1 - 12 of 324 Results');

OR

preg_match('~\d+\s+Results$~i', 'showing 1 - 12 of 324 Results', $m);
var_dump ( $m[0] );

You could use preg_match().

preg_match('/(?P<results>\d+)\sResults$/', $str, $matches);

CodePad.

Then examine $matches['results'] for the number of results or $matches[0] for the number of results and the ' Results' substring.
