[SOLVED] Problems with Array

[david212]

Hello! Im a newbie on php and I have a problem with arrays. I have  4 strings using arrays (something like this:

$a = array("nick","room","id","channel");

 

and i try to put on every first letter of this array strings the different color, for example, "color=red". I tried to do using for loop:

 

<?php

$a = array("nick","room","id","channel");

$s=sizeof($a);

for($i=0;$i<$s;$i++){

echo($a[$i]."<br>");

if($i%2==0)

{

echo("<span style="color:red;">".($a[$s])."</span>");

}

}

?>

and the result must be something like this:

nick

room

id

channel

but it does nothing! Can anyone help me?

Thanx

Sure

 

Your code does not work, because $s is not defined, so $i < $s in for loop always fails

There are also other issues with your code

 

I'd do it this way

 

$a = array("nick","room","id","channel");
foreach($a as $word) {
  echo "<span style=\"color:red;\">".substr($word,0,1)."</span>".substr($word,1);
}

 

should work, though I didn't test it.

See foreach and substr in manual to see how they work

Thank you

Thank you 

 

sorry, i have a question, why this code doesn't work?Could you tell me? I've tried to convert your function in for loop

 

 

<?php

 

 

$a = array("nick","room","idle","channel");

 

 

$s=sizeof($a);

 

for($i=0;$i<$s;$i++)

 

{

$s2=strlen($a[$i]);

if($s2%2==0){

echo("<span style=\"color:red;\">".$a[$i][($s2)-4]."</span>");

 

}

 

echo($a[$i]."<br>");

 

 

 

}

 

?>

 

the result i recieve is:

 

nnick

rroom

iidle

channel

 

and the result must be the same which in the function you created.

 

Thank you

I just have no idea why you're overcomplicating things like this....

 

This

echo($a[$i]."<br>");

displays whole word, but you need to drop the first letter, as you have already displayed it.

good luck
