Useful PHP Tools

[RickM]

On my 'localhost' I have a directory called 'tools' which contains a bunch of PHP scripts I've put together to perform a bunch of basic actions. Actions such as converting a string to MD5 or SHA1, encoding/decoding base64, password generators, hash generators, un/serialize, time, etc.

Basically a bunch of 'snippets' that make developing easier.

This thread is to be used to share your tools with others. As/when I make tools, I'll add them here. Feel free to improve on them and post them back!

MD5 Generator

This script is a simple textbox. Simply enter the string you wish to convert and hit the button. You are presented with a MD5 hash from your string.

The Code:

<?php

if(isset($_POST['submit']))
{
    $md5 = md5($_POST['md5']);
    echo $md5;
}
?>
<form action="" method="post">
    <input type="text" name="md5" /> <input type="submit" value="Gen MD5" name="submit" />
</form>

SHA1 Generator

(Note: Almost identical to the MD5 generator. You could even put the two together with 2 submit buttons - one for MD5 or one for SHA1)

This script is a simple textbox. Simply enter the string you wish to convert and hit the button. You are presented with a MD5 hash from your string.

The Code:

<?php

if(isset($_POST['submit']))
{
    $sha1 = sha1($_POST['sha1']);
    echo $sha1;
}
?>
<form action="" method="post">
    <input type="text" name="sha1" /> <input type="submit" value="Gen SHA1" name="submit" />
</form>

Base64 Encoder/Decoder

This script allows you to encode and decode base_64 strings.

The Code:

<?php 
// Setting str just to stop an undefined error
$str=null;

if(isset($_POST['decode'])) 
{
    $str = base64_decode($_POST['data']);
}
elseif(isset($_POST['encode'])) 
{
    $str = base64_encode($_POST['data']);
}
?>
<form action="" method="post">
<textarea rows="15" cols="80" name="data"><?php echo $str; ?></textarea>
<br />
<input type="submit" name="decode" value="Base64 Decode" /> | <input type="submit" name="encode" value="Base64 Encode" />
</form>

Current Unix Timestamp

A pretty simple one Just shows the current unix timestamp.

The Code:

<?php echo time(); ?>

[RickM]

Domain to IP

Works out and returns the IP address of a domain name.

The Code:

<?php

if($_POST['getdomainip_submit']) 
{
    $domain = htmlentities(addslashes($_POST['getdomainip_string']));
    $domainip = gethostbyname($domain);
    echo'The IP Address for the domain "'.$domain.'" is <input type="text" value="'.$domainip.'" />';
}
else 
{
?>
<form action="" method="post">
    <input type="text" name="getdomainip_string" /> <input type="submit" name="getdomainip_submit" value="Fetch Domain's IP" />
</form>
<?php } ?>

Random String Generator

Generates a long random string based on a list of characters. This first runs a bunch of random encryptions on a big, unique number then uses whirlpool hashing to create a long string.

Note: You can change the encryption from whirlpool to something else supported by php's hash() function.

The Code:

<?php
$str = (time()*rand(5, 15))*(time()*rand(5, 15))+(time()*rand(5, 15)*time());

$str = md5(sha1($str));
$str = hash('whirlpool', $str);

echo $str;
?>

Email Form

NOTE: This is designed for LOCAL use only (mainly to test if your mail server works) - This is not secure enough to use in a production environment! -- You have been warned! Please also note that this is old - its in a simple table - not designed to look pretty!

This email form allows you to send an email to any address, from any address. Designed mainly to test if a localhost can send emails.

The Code:

<?php
if(isset($_POST['submit'])) 
{

    $subject = htmlentities($_POST['subject']);
    $message = htmlentities($_POST['detail']);
    $mail_from = htmlentities($_POST['customer_mail']);
    $header="from: ".htmlentities($_POST['from'])." <".htmlentities($_POST['from']).">";
    $to = htmlentities($_POST['to']);
    $send_contact=mail($to,$subject,$message,$header);

    if($send_contact)
    {
        echo "Message Sent!";
    }
    else 
    {
        echo "Houston, we have a problem!";
    }
}

?>
<table width="400" border="0" align="center" cellpadding="3" cellspacing="1">
    <tr>
        <td><strong>Contact Form </strong></td>
    </tr>
</table>

<table width="400" border="0" align="center" cellpadding="0" cellspacing="1">

nice tutorial.

Image Resizing

This is upload only and requires you have the gd-lib installed.
set the $size_to to the size(du) and $target to the target path. you only need to set the path up to the file name, the extension is taken care of by $extension.

$size_to =100;
$imagename = $_FILES['new_image']['name'];
$source = $_FILES['new_image']['tmp_name'];
$imgtype = $_FILES['new_image']['type'];
$extensionfind = strpos($imgtype, "/" );
$extensionlock = ($extensionfind + 1 );
$extension = strtolower(substr("$imgtype", $extensionlock ));
$target = "path/to/file.$extension";
move_uploaded_file($source, $target);
$file = "$target"; 
$save = "$target";
list($width, $height) = getimagesize($file) ; 
if ($extension == "jpg" || $extension == "jpeg" || $extension == "png" || $extension == "gif")
{
$img_data_size = $_FILES['new_image']['size'];
if ($img_data_size < 8388608)
{
if ($width > $size_to)
{ 
$modwidth = $size_to; 
}
else
{
$modwidth = $width ;
}
$diff = $width / $modwidth;
$modheight = $height / $diff; 
$tn = imagecreatetruecolor($modwidth, $modheight) ; 
if( $extension == "jpg" || $extension == "jpeg" ) { $image = imagecreatefromjpeg ($file); }
if( $extension == "gif" ) { $image = imagecreatefromgif ($file);  }
if( $extension == "png" ) { $image = imagecreatefrompng ($file);  } 
imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; 
if( $extension == "jpg" || $extension == "jpeg" ) { imagejpeg($tn, $save, 100) ;  }
if( $extension == "gif" ) { imagegif($tn, $save, 100) ;  }
if( $extension == "png" ) { imagepng($tn, $save, 9) ;  }
}
else
{
$image_upload_error ="Images must be under: 8MB";
}
}
else
{
$image_upload_error ="Image was not an accepted format. Accepted types are jpg - jpeg - gif - png";
} 

if (isset($image_upload_error)){ echo "$image_upload_error"; }
