indexOf and lastIndexOf in PHP? -

in java, can use indexof , lastindexof. since functions don't exist in php, php equivalent of java code?

if(req_type.equals("rmt"))     pt_password = message.substring(message.indexof("-")+1); else      pt_password = message.substring(message.indexof("-")+1,message.lastindexof("-")); 

you need following functions in php:

strpos find position of first occurrence of substring in string

strrpos find position of last occurrence of substring in string

substr return part of string

here's signature of substr function:

string substr ( string $string , int $start [, int $length ] ) 

the signature of substring function (java) looks bit different:

string substring( int beginindex, int endindex ) 

substring (java) expects end-index last parameter, substr (php) expects length.

it's not hard, get end-index in php:

$sub = substr($str, $start, $end - $start); 

here working code

$start = strpos($message, '-') + 1; if ($req_type === 'rmt') {     $pt_password = substr($message, $start); } else {     $end = strrpos($message, '-');     $pt_password = substr($message, $start, $end - $start); }
