\"HumanMathTest<\/p>\n

I’ve published my first contribution to the FOSS<\/a> community on github<\/a>: HumanMathTest<\/strong><\/a> implements a math test ‘bot deterrent PHP class for use in online forms.<\/p>\n

This class is used to create an image to be included in an online form that shows a simple math test the visitor must solve when submitting the form. The operands and operation are stored in the $_SESSION<\/span><\/strong> data for the page. After submitting the form, the visitor’s answer is checked by calling the verify()<\/span><\/strong> method to compare their entry vs. the session data. If an error is found, the form submission should be rejected.<\/p>\n

The demo page<\/a> illustrates many of the options available, and includes a link to download<\/a> the fully commented source code, including that of the demo and example pages.<\/p>\n
