This approach is mostly preferred because it is faster and demands less memory.Īssumptions: Let?s assume we have one string called $flashlight and another string called $flash. In our example, we will use the strpos() function technique to find whether a PHP string contains another string. This function uses the syntax char *strpbrk(const char *s1, const char *s2). strpbrk ? this is another inbuilt string function that returns a string from a character identical to any character specified in a PHP string.This function is commonly used as it is the easiest method to assist PHP find string in string. strpos ? the strpos() function returns the position of the first occurrence of a string in another string.The syntax for this function is char *strrchr(const char *str, int character) strrchr ? this C library function searches for the last occurrence of c (the character) in a string.It locates a pointer to the first occurrence without considering case sensitivity. stristr? the stristr function is similar to the strstr one, only that it is case-insensitive. The strstr( ) function uses the following syntax to enable PHP?to find a?string in another string:Ĭhar * strstr ( const char *, const char * ) Ĭhar * strstr ( char * str1, const char * str2 )
