Snippet in PHP for Unzipping a File



Using this below PHP snippet, you can be able to unzip a file on it whenever you rip with this code running through PHP. The initial unzip function checks the file to unzip and sees a location with an unlink action confirming the unzipping environment you execute. Making use of this coding process has better results you comply with as unzipping software’s are not reliable and might cause bad sectors on your hard disk.

function unzip($location,$newLocation)
{
        if(exec("unzip $location",$arr)){
            mkdir($newLocation);
            for($i = 1;$i< count($arr);$i++){
                $file = trim(preg_replace("~inflating: ~","",$arr[$i]));
                copy($location.'/'.$file,$newLocation.'/'.$file);
                unlink($location.'/'.$file);
            }
            return TRUE;
        }else{
            return FALSE;
        }
}
function unzip($location,$newLocation)
{
        if(exec("unzip $location",$arr)){
            mkdir($newLocation);
            for($i = 1;$i< count($arr);$i++){
                $file = trim(preg_replace("~inflating: ~","",$arr[$i]));
                copy($location.'/'.$file,$newLocation.'/'.$file);
                unlink($location.'/'.$file);
            }
            return TRUE;
        }else{
            return FALSE;
        }
}
<?php
unzip('test.zip','unziped/test'); //File would be unzipped in unziped/test folder
?>
<?php
unzip('test.zip','unziped/test'); //File would be unzipped in unziped/test folder
?>

Zipping a File in PHP

Using the below PHP snippet, you would be able to zip files instantly:

This code snippet is to zip files instantly and immediately, which has prominent advantages to cut down disk space where you store files, intended for recurrent use on your PC computer. Making initial declaration of how you want to zip file parameters defined through the first function and have a reliable stream of signals and characters compressed to zip a file you want with reduced space.

function create_zip($files = array(),$destination = '',$overwrite = false) { 
    //if the zip file already exists and overwrite is false, return false 
    if(file_exists($destination) && !$overwrite) { return false; }

                $valid_files[] = $file; 
            } 
        } 
    }

    if(count($valid_files)) { 
        //create the archive 
        $zip = new ZipArchive(); 
        if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) { 
            return false; 
        }

        }

PHP Snippets for Different Operations

PHP Snippet to Resize Image:

Sometimes clients can upload a large image, as you might want to resize it. Below PHP Development snippet would enable you to do that. Changing the size of an image is important when you are looking for fitting a visual or banner in a location having limited space, still promoting you further after you use this code snippet for the purpose.


function resize_image($filename, $tmpname, $xmax, $ymax) 
{ 
    $ext = explode(".", $filename); 
    $ext = $ext[count($ext)-1];
    if($ext == "jpg" || $ext == "jpeg") 
        $im = imagecreatefromjpeg($tmpname); 
    elseif($ext == "png")
        $im = imagecreatefrompng($tmpname); 
    elseif($ext == "gif") 
        $im = imagecreatefromgif($tmpname);   
    $x = imagesx($im); 
    $y = imagesy($im);     
    if($x <= $xmax && $y <= $ymax) 
        return $im; 
    if($x >= $y) { 
        $newx = $xmax; 
        $newy = $newx * $y / $x; 
    } 
    else { 
        $newy = $ymax; 
        $newx = $x / $y * $newy; 
    }      
    $im2 = imagecreatetruecolor($newx, $newy); 
    imagecopyresized($im2, $im, 0, 0, 0, 0, floor($newx), floor($newy), $x, $y); 
    return $im2;  
}
function resize_image($filename, $tmpname, $xmax, $ymax) 
{ 
    $ext = explode(".", $filename); 
    $ext = $ext[count($ext)-1];
    if($ext == "jpg" || $ext == "jpeg") 
        $im = imagecreatefromjpeg($tmpname); 
    elseif($ext == "png") 
        $im = imagecreatefrompng($tmpname); 
    elseif($ext == "gif") 
        $im = imagecreatefromgif($tmpname);
    $x = imagesx($im); 
    $y = imagesy($im); 
    if($x <= $xmax && $y <= $ymax) 
        return $im; 
    if($x >= $y) { 
        $newx = $xmax; 
        $newy = $newx * $y / $x; 
    } 
    else { 
        $newy = $ymax; 
        $newx = $x / $y * $newy; 
    } 
    $im2 = imagecreatetruecolor($newx, $newy); 
    imagecopyresized($im2, $im, 0, 0, 0, 0, floor($newx), floor($newy), $x, $y); 
    return $im2;  
}
