I want to find the no of occurences of a sustring(pattern based) inside another string. For example:
$mystring = "|graboard='KERALA'||graboarded='KUSAT'||graboard='MG'";
I want to find the no of graboards present in the $mystring,
So I used the regex for this, But how will I find the no of occurrence?
If you must use a regex, preg_match_all() returns the number of matches.
Use preg_match_all:
$mystring = "|graboard='KERALA'||graboarded='KUSAT'||graboard='MG'";
preg_match_all("/(graboard)='(.+?)'/i", $mystring, $matches);
print_r($matches);
will yield:
Array
(
[0] => Array
(
[0] => graboard='KERALA'
[1] => graboard='MG'
)
[1] => Array
(
[0] => graboard
[1] => graboard
)
[2] => Array
(
[0] => KERALA
[1] => MG
)
)
So then you can use count($matches[1]) -- however, this regex may need to be modified to suit your needs, but this is just a basic example.
Just use preg_match_all():
// The string.
$mystring="|graboard='KERALA'||graboarded='KUSAT'||graboard='MG'";
// The `preg_match_all()`.
preg_match_all('/graboard/is', $mystring, $matches);
// Echo the count of `$matches` generated by `preg_match_all()`.
echo count($matches[0]);
// Dumping the content of `$matches` for verification.
echo '<pre>';
print_r($matches);
echo '</pre>';
