implode - Join array elements with a string

SYNOPSIS

       string implode (string  $glue, array  $pieces)

DESCRIPTION

       string implode (array  $pieces)

	Join array elements with a $glue string.

       Note

	      implode(3)  can,	for historical reasons, accept its parameters in either order. For consistency with explode(3), however, it may be
	      less confusing to use the documented order of arguments.

PARAMETERS

	      o $glue
		- Defaults to an empty string.

	      o $pieces
		- The array of strings to implode.

RETURN VALUES

	Returns a string containing a string representation of all the array elements in the same order, with the glue string  between	each  ele-
       ment.

EXAMPLES

       Example #1

	      implode(3) example

	      <?php

	      $array = array('lastname', 'email', 'phone');
	      $comma_separated = implode(",", $array);

	      echo $comma_separated; // lastname,email,phone

	      // Empty string when using an empty array:
	      var_dump(implode('hello', array())); // string(0) ""

	      ?>

NOTES

       Note

	      This function is binary-safe.

explode - Split a string by string

SYNOPSIS

       array explode (string  $delimiter, string  $string, [int  $limit])

DESCRIPTION

	Returns an array of strings, each of which is a substring of $string formed by splitting it on boundaries formed by the string $delimiter.

PARAMETERS

	      o $delimiter
		- The boundary string.

	      o $string
		- The input string.

	      o $limit
		- If $limit is set and positive, the returned array will contain a maximum of $limit elements with the last element containing the
		rest of $string.  If the $limit parameter is negative, all components except the last -$limit are returned.  If the $limit parame-
		ter is zero, then this is treated as 1.

       Note

	       Although implode(3) can, for historical reasons, accept its parameters in either order, explode(3) cannot. You must ensure that the
	      $delimiter argument comes before the $string argument.

RETURN VALUES

	Returns an array of strings created by splitting the $string parameter on boundaries formed by the $delimiter.

	If $delimiter is an empty string (""), explode(3) will return FALSE. If $delimiter contains a value that is not contained in $string and a
       negative $limit is used, then an empty array will be returned, otherwise an array containing $string will be returned.

EXAMPLES

       Example #1

	      explode(3) examples

	      <?php
	      // Example 1
	      $pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
	      $pieces = explode(" ", $pizza);
	      echo $pieces[0]; // piece1
	      echo $pieces[1]; // piece2

	      // Example 2
	      $data = "foo:*:1023:1000::/home/foo:/bin/sh";
	      list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);
	      echo $user; // foo
	      echo $pass; // *

	      ?>

       Example #2

	      explode(3) return examples

	      <?php
	      /*
		 A string that doesn't contain the delimiter will simply
		 return a one-length array of the original string.
	      */
	      $input1 = "hello";
	      $input2 = "hello,there";
	      var_dump( explode( ',', $input1 ) );
	      var_dump( explode( ',', $input2 ) );

	      ?>

	      The above example will output:

	      array(1)
	      (
		  [0] => string(5) "hello"
	      )
	      array(2)
	      (
		  [0] => string(5) "hello"
		  [1] => string(5) "there"
	      )

       Example #3

	      $limit parameter examples

	      <?php
	      $str = 'one|two|three|four';

	      // positive limit
	      print_r(explode('|', $str, 2));

	      // negative limit (since PHP 5.1)
	      print_r(explode('|', $str, -1));
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => one
		  [1] => two|three|four
	      )
	      Array
	      (
		  [0] => one
		  [1] => two
		  [2] => three
	      )

       Note

	      This function is binary-safe.
