Strpos uses

[dotkpay]

Hello,

 

Am a little puzzled on how to effectively determine if a character exists in a string. I am trying to come to grips with the function strpos but its a little confusing.

 

If am searching for an underscore in a string and want to echo yes if the string contains an underscore, would the code below be right?

 

Would it be right to exclude booleans TRUE and FALSE

 

Example 1

<?php
$string = "Hello_World";

if(strpos($string, "_"))
{
echo "yes";
}

 

OR do I have to include the booleans TRUE/FALSE

 

Example 2

<?php
$string = "Hello_World";

if(strpos($string, "_") == TRUE)
{
echo "yes";
}

Yes.

You said yes, but to which example, the first or second?

Because strpos returns either an integer indicating the position in which the string was found (which may include 0), or FALSE if not found, use a strict comparison to NOT FALSE if you just want to see if the string is found.

 

<?php
$string = "Hello_World";

if( strpos($string, "_") !== FALSE ) {
     echo "yes";
}
