Get string in between certain characters

PHP
1

Hi guys

I need to get the number after each v and echo it out

$var="v9v10v11v12";

What would be the best way to do this?

Try str_replace(…) or implode(…) and explode(…) to get individual numbers into an array().

Example of explode …

<?php
$str="v9v10v11v12";
$arr=explode("v",$str);
foreach ($arr as $key=>$val) {
    echo $key ." is ". $val ."<br>";
}
?>

or

<?php
$str="v9v10v11v12";
$arr=explode("v",$str);
var_dump($arr);
?>

Just beware that the first element of your array will be empty if you use explode on a string that begins with v.
You can handle this by ignoring the first element, [FPHP]array_shift[/FPHP]'ing it off the front of the array, or by using [FPHP]preg_split[/FPHP] with the appropriate flag instead;


foreach ($arr as $key=>$val) {
    if($key != 0) { echo $key ." is ". $val ."<br>"; }
}



array_shift($arr);


$arr = preg_split("~v~",$str,-1,PREG_SPLIT_NO_EMPTY);
