A composer is a tool for dependency management in PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you.
Composer requires PHP 5.3.2+ to run. A few sensitive PHP settings and compile flags are also required, but when using the installer you will be warned about any incompatibilities.
To install packages from sources instead of simple zip archives, you will need git, svn, fossil or hg depending on how the package is version-controlled.
Composer is multi-platform and we strive to make it run equally well on Windows, Linux, and macOS.
1) Use PHP to download the composer installer, place it in the current directory, and name it composer-setup.php 2) Use PHP to check the hash of the file you downloaded and compare it to the known value of the hash. You can always find the current value of the hash for the installer on the Composer Public Keys / Signatures page. 3) Run the setup program to install the composer. This does more than just download the latest copy of the composer, it also sets up your local ~/.composer directory. This will install the composer into the current directory. You can add the –install-dir=DIR to specify where you want the composer installed. You can also specify –filename=composer to change the installed filename. You can use anything you like that doesn’t already exist in your specified directory, you don’t have to use the name composer. This is a great way to get rid of the .phar at the end of the name if you don’t like it. 4) Use PHP to remove the installer from the current directory.
To install composer for PHP you use PHP to download the installer, set a few options, and then actually perform the install.

Many times we need to create logs in our Web Applications to track any certain Errors or Response. We just need to put a bunch of code where you want to Create a log. In this post you will learn how to create logs using Php Code.
$log="User: ".$_SERVER['REMOTE_ADDR'].' - '.date("F j, Y, g:i a").PHP_EOL.
This code will check for the filename. If its available then it will write into the file and if code does not find the file it will create the new for of given name and will write the Logs. You can also use this code in any function you want.
There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config[‘index_page’] added to the address it creates. Presumably, this would be if you were using a media controller:
Additionally, an associative array can be passed to the img() function for complete control over all attributes and values. If an alt attribute is not provided, CodeIgniter will generate an empty string.
'alt'=>'Me, demonstrating how to eat 4 slices of pizza at one time',
'title'=>'That was quite a night',
