Strings and arrays...?

[Patrick3002]

 

<?php
$var1="abcdefghij";
for ($i=0;$i<strlen($var1);$i++) {
     
 echo $var1[$i].'<br>';
}
?>

 

Using that code above... How would i select more than one letter at a time and put it into individual strings for example:

 

If i used that code and wanted to be able to so this:

 

echo $var1[abc]; ( outputs 'abc' )

echo $var1[def]; ( outputs 'def' )

echo $var1[ghij]; ( outputs 'ghij' )

 

 

How would i modify that script to do that?

Use str_split($var1, 3)...

You could make a function to do what you want, but it's much simpler to use str_split()...

But what if i wanted to choose which chars to display like...

 

if i wanted one var to be 'abc', one to be 'dac', or one to be 'hijb'?

[Orio]

I can't really see a pattern here... Define exactly what the function you are looking for should make.

Anyway, if you know what letters you want to display (IE- you dont need to display them by position or something), just output them directly...

I want to take a string i.e: $var1="abcdefghijklmnopqrstuvwxyz"; and create a function to where i can select w/e i want from that variable wether it be 'kl' or 'def' or w/e.

 

hopefully you understand its kinda weird

[Orio]

So if you want a variable that has kl in it, create $kl = "kl"... I just don't understand your point.

I want to be able to grab any part of a string and put it in another string

 

so if i had:

 

$image="custom/images/logo2.jpg";

 

i want to now echo image but i only want to echo /images/logo2.jpg i want to echo everything but custom

 

 

[Orio]

<?php

echo substr($image, strlen("custom"));

?>

 

Orio.

Ok, kewl.

 

Is there some kind of array function that looks like this:

 

$image[2];

 

That'll display the second array or something?

[Patrick3002]

Something like this....

 

 

$numbers = array("1","2","3","4","5");

echo $numbers[0]; (outputs 1)
echo $numbers[1]; (outputs 2)

etc...

 

But instead i can use strings in the array func... is that right??

 

so like this: array("$var1","$var2","$var3");

 

can i use vars in an array func??

The script in your second post will work, but I haven't understood you question.
