php check if the string is real

I want to make a php function that handle a text string and path it to a special algorithm to detect if this text is meaningful or not, and rat开发者_如何学运维e the text from 0 to 100% readability score.

For example:

"skjg askjf akdjf akdjf " will take about 30%. "Hello guys" 90%. "ahdkjshdkjshdkljshdlksjdh" 10% or less.

I hope that make sense.

Here is something to check out: https://github.com/DaveChild/Text-Statistics

This project describes itself as:

The PHP Text Statistics class will help you to indentify issues with your website content, especially with readability. It allows you to measure the readability of text using common scoring systems, including:

• Flesch Kincaid Reading Ease
• Flesch Kincaid Grade Level
• Gunning Fog Score
• Coleman Liau Index
• SMOG Index
• Automated Reability Index

The code that generates the statistics is in a simple class structure. There are also several unit test classes to ensure that changes made don't break existing functionality. There is also a live version of this tool.
