Returning array from Function

[brooky]

I have looked at php.net and tried to find the solution but can't so I am seeking some help from kind people such as your selves. 😃

I have a function which builds an array... ( this is a non working example):

function make_array($array1){

 foreach($array as $key => $value){


 $array2[]=$value;


}
 print_r($array2); // it prints out the array here
}
print_r($array2); // it wont print array here

I have tried adding return $array but it wont work 🙁

It should work.

You'll have to give a non-working example that you think should work.

Here is the actual code I'm working with:

 function  stripos_words($haystack,$needles_array,$pos_as_key=true) 
        { 
        for ($iz=0;$iz<sizeof($needles_array);$iz++) 
            { 
            $needles=$needles_array[$iz]; 
            $idx=0; // Used if pos_as_key is false 

        // Convert full text to lower case to make this case insensitive 
        $haystack = strtolower($haystack); 

        // Split keywords and lowercase them 
        $needle=strtolower($needles); 


        // Get all occurences of this keyword 
        $i=0; $pos_cur=0; $pos_found=0; 
        while ( $pos_found !== false ) 
            { 
            // Get the strpos of this keyword (if thereis one) 
            $pos_found = strpos(substr($haystack,$pos_cur),$needle); 
            if ( $pos_found !== false ) 
                { 
                // Set up key for main array 
                $index = $pos_as_key ? $pos_found+$pos_cur : $idx++; 

                // Populate main array with this keywords positional data 
                $positions[$index]['start'] = $pos_found+$pos_cur; 
                $pos_cur += ($pos_found+strlen($needle)); 
                $positions[$index]['endish']  = $pos_cur; 
                // find the close of the > 
                $pos_cur = strpos($haystack, '>', $pos_cur);  
                $positions[$index]['end']  = $pos_cur; 
                // 
                $positions[$index]['word'] = $needle; 
                $i++; 

                $thechars[]=$positions[$index]['start']; 
				$thestring[]=strlen($needle);
				$num=$positions[$index]['start']; 

				//echo substr($haystack,$positions[$index]['start'],strlen($needle));

				 }

            } 

        } 
     // now we do something really special
	// The results will be ordered as follows arrayValue1,arrayValue1,arrayValue1,arrayValue2,arrayValue2,arrayValue2,
	// therefore we have to work out which key relates to which array value :-/ (Al shits the bed!)

	$amountKeys = count($thechars);
	for ($i = 0; $i <= (count($thechars)/2)-1; $i++) {

	$startPos = $thechars[$i]+$thestring[$i];
	// find key related to current key
	$endKey = ($amountKeys/2)+($i);

	$endPos = $thechars[$endKey]-$startPos;

	// lets make our attributes :)
	$formAttributes[] = substr($haystack,$startPos,$endPos);
	//echo "formAttributes = ".$formAttributes[$i]."<br>";
	$htmlVariables[] = substr($haystack,$startPos-$thestring[$i],$thestring[$i]+strlen($formAttributes[$i])+$thestring[$endKey]);
	//echo "htmlVariable = ".$htmlVariables[$i]."<br>";
	} 

	print_r($htmlVariables); // THIS LINE WORKS

}

stripos_words($html,array("[MULTI(n)]","[/MULTI]"),$pos_as_key=false);

print_r($htmlVariables); // THIS LINE DOES WORK 

Look at the print_r bits. I need to return the array out of the function to use further down the page.

[laserlight]

hmm... it looks like $htmlVariables is local to the function.

assuming that your implementation is correct, then you should

return $htmlVariables;

at the end of stripos_words()

Then use:

$htmlVariables = stripos_words($html,array("[MULTI(n)]","[/MULTI]"),false);

P.S.: I sense the evil Hungarian notation around somewhere :p

Yipiee it works and you taught me something!! 🙂
