String comparing and replacing help

[gte806e]

Ok im trying to test if the name of the image beng uploaded already exists. If it does not then add its name to the image string.

$img1 = '02.gif';
$imgStr = '00.jpg,02.jpg,03.jpg';

However, the important part is its number. So lets remove the extension. Because we want to allow for the ability to change the image type.

$tmpImg = explode(".", $img1);

if( substr_count($imgStr, $tmpImg[0]) == 0 ){
    // Add new item no match was found.
}
else{
   // Check extension match was found
}

Now since we realize that 02 does infact exist. We need to check if its extension is the same as the entry in the $imgStr. If not replace the extension. What would be the best way to do this?

Thanks,

Jesse

Why not just put the names of the images in an array and then search through it. If the file type is going to be constant you don't have to put the extension in there.

Like so:

<?php

$img1 = "02.jpg";
$imgArr = array('00.jpg', '01.jpg', '03.jpg');

if (in_array($img1, $imgArr))
{
    echo "Element exists.";
}
else
{
   echo "Element does not exist.";
}

?>

RegExp !
😃

if (ereg("(.*)\\.(.*)", $filename,$regs)) {
   echo "Image name :".$regs[1];
   echo " extension : ".$regs[2];
}

The fiel name without extension is retained in $reg[1] and the extension in $regs[2].

Well, then you can just leave the extension in there. in_array() won't return true unless it is an exact match. I think in_array() is faster than regexp.
