how to explode or split or chunk in an efficient way

[Negin Nickparsa]

I have a string which always has "C" then a number which it's length can
change anytime and then "P" and then a space and then a word

like:

echo "C60P1 Unit";

is it anyway to split the string by type?

from the manual I did this:

function multiexplode ($delimiters,$string) {
$ary = explode($delimiters[0],$string);
array_shift($delimiters);
if($delimiters != NULL) {
foreach($ary as $key => $val) {
$ary[$key] = multiexplode($delimiters, $val);
}
}
return $ary;
}
echo "C60P1 Unit";
$str="C60P1 Unit";
$delimiters = Array("C","P"," ");
$res = multiexplode($delimiters,$str);
echo '<pre>';
print_r($res);
echo '</pre>';

but it seems to me it is so complex for such a small string
does anything for type exist which I don't know about to for example just
grab the numbers?because I just care about the numbers here 60 and 1
seperately

Your problem is best solved with regex. I'm not a user of such myself,
but someone will come along shortly I'm sure.

​Jomali yeah! yours is nice too
Jim I solved it with guidance of Jeffery! and yes preg_match thank you!

preg_match('/([a-z]+)(\d+)([a-z]+)(\d+)/i', $str, $matches);​

One method is to use regular expressions e.g.:
$pattern = '/C([0-9]+)P/';
preg_match($pattern, $str, $matches);

$matches is an array. $matches[1] contains the number you want.

preg_match_all('/\d+/', $str, $matches);

print_r($matches);

Or to make sure the delimiters are there:

preg_match('/C(\d+)P(\d+)/', $str, $matches);

Try this

<?php

$in = "C60P1 Unit";
$regex = "/C(?P<C>[0-9]+)P(?P<P>[0-9]+) (?P<D>.*)/";
preg_match($regex, $in, $m);
print_r($m);

?>

Array
(
[0] => C60P1 Unit
[C] => 60
[1] => 60
[P] => 1
[2] => 1
[D] => Unit
[3] => Unit
)

This doesn't match your description... there's a number after the 'P' :)

Sorry, I missed that you want the 60 and the 1... I think others have
done similarly but just to be different here's another take:

<?php

$str = 'C60P1 Unit';

list( $num1, $num2 ) =
explode( ':', preg_replace(
'#^[^[:digit:]]+([[:digit:]]+)[^[:digit:]]+([[:digit:]]+).*$#', '\1:\2',
$str ) );

echo $num1."\n";
echo $num2."\n";

?>

Cheers,
Rob.
