[SOLVED] return true or false with stripos

[porta325]

Hey guys, can anyone tell me how can i do to stop execution of a loop if one value returns true ?

Here is my script:

$aaa = ("08408041333118");

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

 

for ($i=0; $i < count($bann);$i++){

 

if ($ban = stripos($aaa,$bann[$i])){

 

echo "-true";

}

else

{

echo "-false";

}

}

 

It returns -true-false-true-true , but i need the loop to stop when it finds the first occurence and only display "number found" only once outside the loop.

Use "break":

 

<?php

$aaa = ("08408041333118");
$bann = array("1","2","3","4");

for ($i=0; $i < count($bann);$i++)
{
if ($ban = stripos($aaa,$bann[$i]))
{
	echo "-true";
	break;
}
else
	echo "-false";
}

?>

 

 

Keep in mind that using breaks is not a very "clean" way to terminate a loop- it can be sometimes unclear to someone who looks at your code and tries to understand what you did.

In this case it's pretty clear tho.

Works nice, thanks.One more question though.

if ($ban = stripos($aaa,$bann[$i])){

$x="true";

break;

}

else

{

$x="false";

}

}

can i assign a variable to each case and then use it outside the loop like this ?

You can do the same thing this way:

 

<?php

$aaa = ("08408041333118");
$bann = array("1","2","3","4");

$x = FALSE;
for ($i=0; $i < count($bann);$i++)
{
if ($ban = stripos($aaa,$bann[$i]) !== FALSE)
{
	$x = TRUE;
	break;
}
}

?>

 

This also fixes the little bug you had in your if.

$aaa = ("08080");

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

 

$x = FALSE;

for ($i=0; $i < count($bann);$i++)

{

if ($ban = stripos($aaa,$bann[$i]) !== FALSE)

{

$x = TRUE;

break;

}

}

if ($x = false){

echo "false";

}

else

{

echo "true";

}

 

this returns true when it should return false. Can't figure out why.I removed the true values from the first string.

if ($x = false)

 

Should be

if ($x == false)

 

 

And remove the brackets around your string ($aaa).
