php - Split a string by forward slash but ignore the <\ in the string -


i have string similar 

word1/word2/word3/<b>word3</b>

i want explode string forward slash. can following result.

array = ( [0] => 'word1', [1] => 'word2', [2] => 'word3', [3] => '<b>word3</b>' );

but i'm unable above result. instead i'm getting following result

array = (     [0] => 'word1',     [1] => 'word2',     [2] => 'word3',     [3] => '<b>word3<',     [4] => 'b>'     );

what regular expression should use use preg_split function achieve expected results?

with preg_split function , specific regex pattern:

$s = 'word1/word2/word3/<b>word3</b>'; $result = preg_split('~(?<!<)/~', $s); print_r($result);

  • ~ - treated regex expression separator

  • (?<!<)/ - negative lookbehind assertion, assures forward slash / not preceded <

the output:

array (     [0] => word1     [1] => word2     [2] => word3     [3] => <b>word3</b> )

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
