PHP STRISTR functions

For the Stristr () function, I'll just use an instance to illustrate:

Parameters	Description
String	The string that must be searched for
Search	The string that must be searched for
Before_search	Optional, default false, which returns the first occurrence of a string in string strings, itself and the remainder of its end, true, which returns the string portion of the string before the first occurrence

Note: the Stristr () function is not distinguished, the string case is case-sensitive, use the STRSTR () function

For Example:

One

echo stristr("google earch!!!",earch);

outputearch!!!

Both:

echo stristr("google earch!!!",earch,true);

outputgoogle 

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the PHP stristr function, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
