Contains, not equals..

[Anon]

Hi experts newbie to PHP :-)

Using "==" in an if statement to make a boolean value only works if both values are the same, but is there any way to find out whether the variable contains specific letters, e.g if someone typed in "Hello World.mp3" into an input box called file, and pressed submit, is there any way to make the if statement turn false if "$file" contains the characters ".mp3" amongst other characters?

yeah.. try something like this..

if(strstr($file, ".mp3")) {
// do stuff
} else {
// do other stuff
}

You can also use the != expression.

Example

#############

IF ($input != "wanted.mp3") {

statements

}else{

statements

}

Nevermind, did not read the thread correctly, sorry LOL.

or:

if ( ereg(".mp3$", $file) )
{ // it ends with .mp3
}
else
{ // doesn't end in .mp3
}
