get text before symbol

[robkar32]

<?php

function func($text) {
	
	$array = explode(' ', $text);
	
	for($i = 0; $i < count($array, COUNT_RECURSIVE); $i++){
		$output = substr($array[$i], strpos($array[$i], "=") + 1);
		echo $output, '<br>';
	}
}
func("arg1=Test1 arg2=test1 arg3=test3");


?>

So this code obviously outputs test1, test2 and test3, which i want it to.

 

Now how do i get the arg's as well? 

 

This is what i want to do:

if(exists('arg1' || 'arg2' || 'arg3') {
	echo "args exists";
} else {
	echo "args don't exist";
}

Hope you understand, thanks!

Where does this weird input string come from? Why not use a proper data format like JSON?

You could use explode() again.

<?php
 
function func($text) {
    $array = explode(' ', $text);
    foreach($array as $currArg){
        $currArg = explode('=', $currArg);
        print '<pre>' . print_r($currArg, true) . '</pre>';
    }
}
func("arg1=Test1 arg2=test1 arg3=test3");
 
?>

Or you can use func_get_args() and not force the function parameter to be a randomly formatted string. Or, pass in an array of values and simply loop through them. Point being, unless you're tied to this data format for the function parameter, there are far easier ways to handle the situation.

Despite the previous concerns about why you are using this strange data format, if you simply stop using the substr function on the input you will get the arg values as well. Of course that is too easy so you muat want something else, but you didn't make that clear in your question.

Yes. I just want to split up the arg values, and the values assigned to them, or the "test" values in different arrays and know where they are. Only thought of a way to get the values, and not the args. Yeah, i'm pretty new to this, and by the way i am not using this code for something big that i even need to worry about the data format.

With a proper data format, this would be a 30-seconds job and not take 6 hours (and counting). So maybe you should care about your decisions.

 

If you're interested in learning PHP, I'm sure we can figure out a more reasonable approach after you've described the actual problem (where does the data come from etc.).

If you haven't already, you could try Reply #3.

You have the 'arg' value and the true value ('test') available to you in your function. If you can't figure out what to do from there, you need to stop working on this and go back to the book and do some learning.
