Maximum lenght

[Maurice79]

I've a made a sum which calculate the procent of a value. To bad it is mostly a long result like 67.32857835 and i'm wondering if there is a code that remove all numbers or characters after the 5th. This means the above result would look like 76.32 and the word 'phpfreaks' would be 'phpfr'.

<?php
function str_trim($str)
{
echo substr($str, 0, 5);
}
?>

Tbh, a google search would have given you what you need.

if you're using numbers you can round that number using round()

 

so round(67.328578235, 2); would give you 67.33

Thanks both for the quik reply! BTW i used google before making this topic, google is  the first who i ask for help but i just didn't find it this time or better said i was not searhing for the correct words.

 

Honestly said i'm not a hero with php actualy just a noob and need a litle bit more help if it is possible.

 

Currenlty i have this.

$percentage = 100 / (($result->ban_length * 60) / ($date_and_ban - $now));

result is 76.123456789

 

Do i need to change it with this?

$percentage = round(100 / (($result->ban_length * 60) / ($date_and_ban - $now)), 2);

result will be 76.12

 

 

 

And i have this.

$player = $result->player_nick;

result is "the name of the player"

 

Actualy i don't know how to work with the below code.

$player = $result->player_nick;

function str_trim($str)

{

echo substr($str, 0, 10);

}

result is "the name of t"

Thanks both for the quik reply!

 

<?php

// the code you posted for this should work ok but I like to use extra parentheses to make things absolutely sure like this:

$percentage = round( ( 100 / ( ( $result->ban_length * 60 ) / ($date_and_ban - $now ) ) ), 2);

//and for this part:

$player = $result->player_nick;

$MaxLength = 10;  //this is the number you change to set the max length of your string

echo substr($player, 0, $MaxLength);   // this will echo this: "The name o"

$MaxLength = 19;

echo substr($player, 0, $MaxLength);   // this will echo this: "The name of the pla"

 

hope that helps
