iconv is a computer program and a standardized API used to convert between different character encodings.
The iconv API is the standard programming interface for converting character strings from one character encoding to another in Unix-like operating systems. Initially appearing on the HP-UX operating system, it was standardized within XPG4 and is part of the Single UNIX Specification (SUS).
A hash function is any algorithm or subroutine that maps large data sets, called keys, to smaller data sets. For example, a single integer can serve as an index to an array (cf. associative array). The values returned by a hash function are called hash values, hash codes, hash sums, checksums or simply hashes.
Hash functions are mostly used to accelerate table lookup or data comparison tasks such as finding items in a database, detecting duplicated or similar records in a large file, finding similar stretches in DNA sequences, and so on.
The GD Graphics Library is a graphics software library by Thomas Boutell and others for dynamically manipulating images. Its native programming language is ANSI C, but it has interfaces for many other programming languages. It can create GIFs, JPEGs, PNGs, and WBMPs. Support for drawing GIFs was dropped in 1999 when Unisys revoked the royalty-free license granted to non-commercial software projects for the LZW compression method used by GIFs. When the Unisys patent expired worldwide on July 7, 2004, GIF support was subsequently re-enabled.
GD is extensively used with PHP, where a modified version supporting additional features is included by default as of PHP 4.3 and was an option before that. As of PHP 5.3, a system version of GD may be used as well, to get the additional features that were previously available only to the bundled version of gd.

$mail->send(“info@phpcodez.com”,”Test”,”Test” , “image1.jpg”,”../images/”,”newsletter@phpcodez.com”,”PHPCodez”,”newsletter@phpcodez.com”);
?>
It prints parsable string representation of a variable
Example
======
<?php
echo “<pre>”;
$array = array(“php”,”codez”, array(“1”, “1”, “7”),1,2);
var_export($array);
?>
Output
=====
array (
0 => ‘php’,
1 => ‘codez’,
2 =>
array (
0 => ‘1’,
1 => ‘1’,
2 => ‘7’,
),
3 => 1,
4 => 2,
)
