• PHP - Finding Strings Within Strings

  Posted on April 15th, 2009 admin No comments

  There are four functions you can use to find strings:

  - strstr()

  - strchr()

  - strrchr()

  - stristr()

  The first function: strstr() can be used to find a string inside another or longer string for example:

  if (strstr($string, ‘computer’))

  echo “The word computer is found”;

  This function is basically testing out whether or not the string ‘computer’ is in the variable $string. If the string is in variable $string it would output “The word computer is found” to the browser.

  The second function we could use is strchr(). This function is the nearly similiar to the first function but this one finds a specific character such as ‘@’ or any other character.

  The third function: strrchr() finds the last occurence of a character or string and then returns all the characters from that point onward. The last function is the stristr() function. This is the same as the strstr() function but it’s not case sensitive so you could find the string whether or not it’s in capitals or not (or both caps and not caps)
