looking for a string function

[michal317]

Hi!
I'm looking for a string function that is one string is found in another string (longer one) it will return TRUE.
for example:
look for xyz in abcxyzde
if it's found - than return TRUE.
thanks!

try

if($test = strpos("abcxyzde","xyz"))
{ echo "Found 'xyz'"; }
else { echo "Cannot find 'xyz'"; }

Not so fast!

if($test = strpos("abcxyzde","abc"))
{ echo "Found 'abc'"; }
else { echo "Cannot find 'abc'"; }

/* above code fails because PHP treats 0 as FALSE */

/* code below works because it checks for FALSE by using === */

if(FALSE === strpos("abcxyzde","abc"))
{ echo "Cannot find 'abc'"; }
else { echo "Found 'abc'"; }

Good catch...I wasn't thinking about it returning 0 (finding the string at the first position)...Thanks ;)

That mistake leads to a whole string of hard to track down bugs ;-)
