Match for a word in a text with the PHP script

[Gabriel9999]

I have an applications developed with PHP. I have a big text file where I want to match for a word but this can be change in the feature. How can I match a word in PHP?

There are different functions and ways to match a word in PHP. Best way is using preg_match() function. In the following example we will search the forum word in the $bigtext content.

preg_match('/forum/',$bigtext)

should we have a dev php using linux sub forum ?

to simply confirm that a word exists but you don't want to do anything with it ; for instance maybe you want to run through a text string that was submitted POST from a contact form to check for spam then you can also use :

strpos($inputString, $keyword)

where $keyword is an array of key words

and something like :

foreach($this->keywords as $keyword)

{

if (strpos($inputString, $keyword) !== false) { do something }

}

captain-sensible, it's a nice solution, thanks for reminding. There are plenty of times, when I'm trying to implement features like that during simple stages of emr development and as you know, when you concentrate on some specific features and code parts - you can easily forget about other great techniques and code snippets.

Well once I had a reply from a guy called Stefan Mischook (k* php) in a conversation about rememebering concepts rather than exact code; he said : "i've forgotten more on code than i know now ! " thats always made me feel comfortable when i need to keep looking things up

if you want to see code in action and have a laugh i will give you a link to a dev/daughter live web site where i'm writing a light c.m.s on top of CodeIgniter4
