count number of strings in variable

hi,

i've got a variable, e.g. $test = "re: re: test" and now i want to know how often a certain string is contained in that variable, i.e. "re:"

any suggestions?

You might want to check the PHP manual, the strings section.

I asked for this last night but no-one seemed to know so I wasn't sure it was possible.

gitarrenhaendler, heres the URL...

(Be aware if you count the number of times hello appears, the string Hello helloworld would give an output of two. Its also case-sensitive)

I just checked this worked...

$num_re = substr_count("$test", "re:");
echo $num_re;

will give the number of re: in the variable.
