Insert text to particular position in a file

[ashly123]

Hi,

 

I am a newbie in string functions in php. I have a text file which contains some lines of text in a particular format.

I am using php to maniputlate this text file.

 

Text1 = This is my first line of text
Text2 = This is my second text
Text3 = This is my third text
Text5 = This is fifth line of text
Text10 = This is tenth line in the file
....
....

 

I would like to insert some missing text at the end or in between the existing lines. For example, I would like to write Text7 in the file in the exact place now. Can anyone please give me a solution for this?

 

After the insertion, the file should look like this:

 

Text1 = This is my first line of text
Text2 = This is my second text
Text3 = This is my third text
Text5 = This is fifth line of text
Text7 = This is seventh line in the file
Text10 = This is tenth line in the file
....
....
