Converting an array to a string array is a very common task in PHP. This operation allows the program to manage data more efficiently, and multiple data items can be combined together for more complex operations. Some common methods are described below.
Method 1: Use the implode() function
PHP's implode() function can combine the string elements in the array into a string and separate them with specific delimiters. The following is an example:
$myArray = array("Hello", "World", "PHP", "is", "Great"); $string = implode(", ", $myArray); echo $string;
The above code output:
Hello, World, PHP, is, Great
Method 2: Use the join() function
Similar to the implode() function, the join() function can also be used Combines string elements in an array into a single string. The only difference is the order of its parameters. Here is an example:
$myArray = array("Hello", "World", "PHP", "is", "Great"); $string = join(", ", $myArray); echo $string;
The above code output:
Hello, World, PHP, is, Great
Although these two functions implement the same function, their parameter order is slightly different. Most of the time, programmers prefer using implode() function as it is more readable.
Method 3: Manually splicing strings
In PHP, manually splicing strings is a common method. You can use a loop to iterate over the array and add each element to the string. The following is an example:
$myArray = array("Hello", "World", "PHP", "is", "Great"); $string = ""; for($i = 0; $i <p>The above code output: </p><pre class="brush:php;toolbar:false">Hello, World, PHP, is, Great
This method can customize the format of the string through looping.
Summary
Converting an array to an array of strings is a task frequently used by PHP programmers. Fortunately, PHP provides several functions to accomplish this task. You can use the implode() or join() functions to form a string, or you can concatenate strings manually to give you complete control over the format of the output.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
