if inside foreach loop not working

[Stargate22]

Hello guys 

$myFile = "smt.txt";
$fh = fopen($myFile, 'r');
$all = fread($fh, filesize($myFile));
$cities = explode ("," , $all);

foreach ($cities as $city) {
        if(0 === strpos($city,'E')){
	    print_r($city);
	}
}

I want to print only the strings from the array $cities that start with E , my code does nothing, not an error, nothing.. if i remove the if and let the print it works.. but I need just thous that start with E.

Do you guys have any tips?

PS: in my array there are a lot of cities that start with E...

Thank you!

What does it show if you remove the if?

@requinix

if i remove the if and let the print_r  it is printing the array like: New York Los Angeles Edinburgh and so on...

[requinix]

Right. I was thinking more of the exact output. And while I'm at it, can you use var_dump() instead?

[hansford]

foreach ($cities as $city) {


        if($city[0] == 'E') {


	    print_r($city);

	}

}

Just show the output of this:

 

var_dump($cities);

 

We want to verify that there is a value that starts with 'E' (not 'e') and that the value doesn't start with a space or some other non-printable character.

Hello,

It prints the array cities like:

array (size=268)

0 => string 'Aboed' (length=5)

1 => string '

Ajold' (length=7)

2 => string '

Afed' (length=6)

3 => string '

... etc

Eugir' (length=7)

82 => string '

Eurtici' (length=9)

83 => string '

.. etc

foreach ($new as $city) {
	$findme = "E";
        $pos2 = strpos($city, $findme);
	#if($pos2 !== false){
             #echo "<li>$city</li>";		
        }
}

^-> above code prints all cities that start with E... but why is my initial code not workin`?

[hansford]

Then use this if you are not sure of the case:

foreach ($cities as $city) {

        if(strtoupper($city[0]) == 'E') {

	    print_r($city);
	}
}

82 => string '

Eurtici' (length=9)

 

Most of the cities in that sample begin with a space (or other non-printing character) and a "\n"

 

In the example I picked out the length is 9 when it should be only 7. You need to trim() the elements in your data

[Stargate22]

@Barand Yeap, because I did not trimmed them it did not work, I`m Blind o.O

Thank you guys for all the help.

@Hansford, thank you for the code!
