count of the elements

[amit_shetye]

hi,
all

one very basic question??

how should i count the particular elements in a string??

for example

$content="Mr.Bush, is the President of U.S."

in the above string i want to count "." so how should i proceed??

regards
amit

one method... and probabally not the best (I know extremely little PHP) is to store the length of the string in a variable..
next, replace "." with ".."
number of "."'s = current length of string minus the original length.

PHP Probabally has a native function to do this, but the above is one method.

the native function is substr_count, the php manual for this is here: http://uk2.php.net/substr_count
