Show the word replacement through printf. The strpos() function returns the position of the first occurrence. Then we compare “read” with “wordToBeFind” and if the result is true, we use “strcpy()” to replace “read” with “wordToBeReplacedWith”. You can use the PHP strpos() function to check if a string contains a specific word or not. Assuming there are several types of files in a directory you wish to search in, you can also. If you want to know the exact line where the string of text exist, include the -n option. If the word is not found, an error message must appear stating that the word was not in the list. The PHP script searches through the 50 words to find the correct word using a loop that runs until the word is found in the a. On the JavaScript side, a client types a random word in a text field and submits the word. Text file contains 50 words, each word is on 1 line. We run a loop till the end of file is reached and scan each word in the file and store it in a variable “read”. To ignore case distinctions employ the -i option as shown: grep -Riw /bin/ -e 'checkroot'. Write PHP script to search for a word in a text file (titled a.txt). enter key) also we just copy the null character of the string one position back so that the newline is replaced with “\0” As using fgets takes the input of new line character(i.e.
