PHP eregi() Function

​

Hello dear readers! welcome back to another section of my tutorial on PHP. In this tutorial guide, we will be discussing about the PHP eregi() Function.

The PHP eregi() function searches throughout a string specified by pattern for a string specified by string. Search with this function is not case sensitive. The eregi() can be specifically very useful when checking for the validity of strings, such as password.

The optional input parameter regs contains an array of all matched expressions that were grouped by parentheses in the PHP's regular expression.
