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

Parameters
separator The boundary string.
string
The input string.
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 parameter is zero, then this is treated as 1.
Note: Prior to darkedeneurope.com 8.0, implode() accepted its parameters in either order. explode() has never supported this: you must ensure that the separator argument comes before the string argument.
Return Values
Returns an array of strings created by splitting the string parameter on boundaries formed by the separator.
If separator is an empty string (“”), explode() will return false. If separator 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() examples
//Example1$pizza=”piece1piece2piece3piece4piece5piece6″;$pieces=explode(“”,$pizza);echo$pieces<0>;//piece1echo$pieces<1>;//piece2//Example2$data=”foo:*:1023:1000::/home/foo:/bin/sh”;list($user,$pass,$uid,$gid,$gecos,$home,$shell)=explode(“:”,$data);echo$user;//fooecho$pass;//*?>
Example #2 explode() return examples
/*Astringthatdoesn”tcontainthedelimiterwillsimplyreturnaone-lengtharrayoftheoriginalstring.*/$input1=”hello”;$input2=”hello,there”;$input3=”,”;var_dump(explode(“,”,$input1));var_dump(explode(“,”,$input2));var_dump(explode(“,”,$input3));?>
The above example will output:
array(1)( <0> => string(5) “hello”)array(2)( <0> => string(5) “hello” <1> => string(5) “there”)array(2)( <0> => string(0) “” <1> => string(0) “”)
Example #3 limit parameter examples
$str=”one|two|three|four”;//positivelimitprint_r(explode(“|”,$str,2));//negativelimit(sincedarkedeneurope.com5.1)print_r(explode(“|”,$str,-1));?>
The above example will output:
Array( <0> => one <1> => two|three|four)Array( <0> => one <1> => two <2> => three)
