LEARN ABOUT PHP

substr_count

SUBSTR_COUNT(3) 							 1							   SUBSTR_COUNT(3)

substr_count - Count the number of substring occurrences

SYNOPSIS

       int substr_count (string  $haystack, string  $needle, [int  $offset], [int  $length])

DESCRIPTION

       substr_count(3)	returns  the number of times the $needle substring occurs in the $haystack string. Please note that $needle is case sensi-
       tive.

       Note

	       This function doesn't count overlapped substrings. See the example below!

PARAMETERS

	      o $haystack
		- The string to search in

	      o $needle
		- The substring to search for

	      o $offset
		- The offset where to start counting

	      o $length
		- The maximum length after the specified offset to search for the substring. It outputs a warning if the offset plus the length is
		greater than the $haystack length.

RETURN VALUES

	This function returns an integer.

       | 5.1.0	|						|

EXAMPLES

       Example #1

	      A substr_count(3) example

	      <?php
	      $text = 'This is a test';
	      echo strlen($text); // 14

	      echo substr_count($text, 'is'); // 2

	      // the string is reduced to 's is a test', so it prints 1
	      echo substr_count($text, 'is', 3);

	      // the text is reduced to 's i', so it prints 0
	      echo substr_count($text, 'is', 3, 3);

	      // generates a warning because 5+10 > 14
	      echo substr_count($text, 'is', 5, 10);

	      // prints only 1, because it doesn't count overlapped substrings
	      $text2 = 'gcdgcdgcd';
	      echo substr_count($text2, 'gcdgcd');
	      ?>
