Merge Array of Characters into a single php variable

  • 772

I need to do what the subject title says, the detail is that it is an array that has a maximum size of 10, so I don't know when they will enter a different size, that is, 10 is not mandatory, but if it is the maximum, I am new to the language.

Go to the end of the code:

<?php
	
	function sevent(int $c){
	if(($c/7)>17)	
	return true;
	else
	return false;
	}

	function sprimo(int $b){
 	 $d=1;  $p=0;

	do{
	if($b % $d == 0)
	$p++;			
	$d++;
		}while($d < $b+1);

	if($p==2)	
	return true;
	else
	return false;
	}



function lenner(string $a)
	{
    $sz = strlen($a); 
	$vector; 
	$cat; 
	$b;
	$i;
    $x;

	for($i=0; $i<$sz; $i++)
		$vector[$i]=ord($a[$i]);
		
	for($i=0; $i<$sz; $i++){
		$x=$vector[$i];		
	if(sprimo($x)){
		$vector[$i]+=5;
		$cat[$i]=1;
		goto jump;
		}
	if(sevent($x)){
		$vector[$i]-=7;
		$cat[$i]=2;
		goto jump;
		}
	else{
		$vector[$i]+=9;
		$cat[$i]=3;
	}	
	jump:

	}
	for($i=0; $i<$sz; $i++)
		$b[$i]=chr($vector[$i]);

	$sub2 =  $b[0] . $b[1] . $b[2] . $b[3] . $b[4] . $b[5] . $b[6] . $b[7] . $b[8] . $b[9] ;
	
	return $sub2;
	}

A million thanks

  1. Use the sizeOf() function

    The simple solution to this is to loop the array size and values ​​to avoid only handling the 10 you mention.

    for($cont=0;$cont<sizeof($b);$cont++)
  $variable+=(string)$b[$cont];

    This at the end of your code. Likewise, each character in the array $bwill be emulated as a string and added to your $variable.

    Thank you all for helping me, I changed the conditions for my encryption function, the answer to my question is this:

    	for($i=0; $i<$sz; $i++){
		$b[$i]=chr($vector[$i]);
		$sub2 .=$b[$i];
	}
	return $sub2;
