#PHP TRIM AFTER ARCHIVE#

There is no PHP function just to check only _if_ $needle occurs in $haystack strpos() tells you if it _doesn't_ by returning false, but, if it does occur, it tells you _where_ it occurs as an integer, which is 0 (zero) if $needle is the first part of $haystack, which is why testing if (strpos($needle, $haystack)=false) is the only way to know for sure if $needle is not part of $haystack. If $needle is the last character in $haystack, and testing $needle as a boolean by itself would evaluate to false, then testing strstr() as a boolean will evaluate to false (because, if successful, strstr() returns the first occurrence of $needle along with the rest of $haystack).Īlso, strstr() is far more memory-intensive than strpos(), especially with longer strings as your $haystack, so if you are not interested in the substring that strstr() returns, you shouldn't be using it anyway. So to cut to 30 characters we would use the following.

The first is the string, the second is where to start cutting from and the third is the amount of characters to cut to. Strstr() is not a way to avoid type-checking with strpos(). string 'This string is too long and will be cut short.' The substr () function has three parameters.
