Ignore last data explode is taking? PHP

问题

let's say my code is.

<?php
$var = "1,2,3,4,5,6,";
$var_explode = explode(',', $var);
foreach ($var_explode as $number)
{
echo "$number test";
}
?>

And when it echos, it goes like, 1 test, 2 test, 3 test, 4 test, 5 test, 6 test, test. The last one is un-needed, I know its caused because I have a comma after the 6 in my variable, but I need that comma there, not going to remove it. Thanks!

回答1:

You can use trim($var, ",") to remove the last comma when passing the string to the explode.

$var_explode = explode(',', trim($var, ","));

回答2:

 <?php

$var = "1,2,3,4,5,6,";
$var_explode = explode(',', $var);
array_pop($var_explode); // removes last  
foreach ($var_explode as $number)
{
echo "$number test";
}
?>
