[Resolved] [Resolved] strstr strrchr help

[helz]

right theres strstr to get the first occurance and strrchr to get the last occurance, but all them are used to get everything after the $needle, but i want to get everything before it..

using a simple divide on 2 numbers so when it gives something with a decimal, say:
433.432425621
instead of getting everthing after the decimal i want to get everything before it, in this example it will be 433

<?
$data="433.432425621";
$seperator = ".";
$output=substr($data,0,strpos($data, $seperator));
echo $output;
?>

[helz]

so the code you posted uses substr where haystack is $data it starts at the first and the length using the strpos would return 4 meaning the 3rd number in $data

thanks lord, i knew youd be the one to help 😃

[LordShryku]

No problem. Check the user comments in the manual on php.net also. I seem to get a lot of useful stuff outta there from time to time 🙂

[helz]

[LordShryku]

Mountain Dew will cure that for ya 😃
