counting

[fishfin]

Is there any way to count the number of instances of a string inside of a longer string?

 

An example would be counting the number of 'e's in 'I like to eat sheep.'

[Daniel0]

echo substr_count('e', 'I like to eat sheep');

[fishfin]

Could I also do this?

 

$x = substr_count('e', 'I like to eat sheep');

 

And another thing, how would I tell it to count the number of <enter>'s in the string?

Yes.

\n means a new line, so you can do:

substr_count("\n", $string);

 

Note that it won't work if you use single quotes.

<?php
$string = "Twas brillig and the slithy toves
	Did gyre and gimble in the wabe
	All mimsy were the borogoves
	And the mome raths outgrabe";
$count = substr_count($string, "\n");                    // NOTE (haystack, needle)

echo $count;                           // --> 3
?>

Oh... it seems I got the order of the arguments wrong. Thanks, Barand.
